What is the most duct-tape thing you've done to Linux?

intel won't allow its linux drivers to work above wifi 4 speeds in ap mode, so i created a kvm virtual windows machine with pci pass through on the wifi nic plus ip masquerade and now i'm getting wifi 6 speeds in ap mode.

My control key was broken, but I found that when I used an app and held down the space bar key, the CPU would get abnormally hot.

So I wrote an Emacs interrupt to interpret a rapid CPU rise as "press the control button".

Unfortunately the dev pushed an update that broke space bar heating, which broke my workflow. I opened a bug report about it, though...

My mother uses some software that runs in the browser for her shop. It can print out receipts and scan items. To do these things it has a small "sattelite" application that runs on the system and interacts with the printer and scanner. This software only runs on Windows and Linux doesn't have drivers for the scanner.

When I switched her over to Linux and found this out in the process I wanted to stop, give up and install windows.

But then I had a stupid idea. I could run the sattelite program in a Windows VM and pass through the USB devices for receipt printer and scanner. The webapp uses requests to localhost:9998 to communicate with the sattelite so I set up a apache server that proxies these requests into the VM. I also prevented the VM from acessing the Interner so Windows doesn't update and screw everything up.

And it works. It has been in use for a week now and I've heard no complaints. I'm just praying to god it doesn't break

I like to use unclutter to hide my mouse pointer after a few seconds without being moved.

Now, the thing is, it doesn't just visually hide the cursor, it actually removes it, so UI elements triggered by hovering disappear. Sometimes that's great, other times it's infurriating, like when reading a tooltip or menu.

I mostly use a touchpad, and so I developed a habit to wiggle my finger while I'm intentionally hovering something, so that there was enough mouse movement for unclutter to not remove my pointer.

Then I found a setting for the jitter threshold of the touchpad. Basically, with the threshold on, it ignores tiny movements, because the hardware reports finger wiggling, even if you hold your finger perfectly still. Which is perfect for me to turn off.

Now when I have my finger on the touchpad, it automatically wiggles and allows me to read hover elements. If I take my finger off, it stops wiggling and removes the cursor.
It's almost like someone designed an OS with touchpads in mind, rather than them being an afterthought.

This certainly isn't of the same caliber as some of these other comments, but I found it to be fitting to the topic.

Last year I was having problems getting the game stellaris working on arch. (I use bazzite now, btw) My solution was the following:

download the game via steam.
switch it to use proton
switch it back to linux version
use the terminal to make the entire game folder read-only, so that steam couldn't touch the game anymore and screw it up.
add the exicutable to PATH
start the game via terminal

If any one of those step was left out, it didn't work. I'm no linux expert, so I didn't have the skills to actuality find the real problem.

I think this one beats them all.

My home server keeps a few services up, including an instance of Jitsi Meet. The server runs nixos and the nixos package for jitsi is incomplete to say the least and doesn't even support authentication, so I use the docker-compose version and I have a script that runs periodically to keep it updated. So far so good, right? Well, no.

Because the server is at home, I have a dynamic external IP address, so I have to use a DDNS provider, but jitsi doesn't expect this and uses a stun server at startup to determine the public IP of the server once, so if my connection goes down or is restarted and the IP changes, jitsi needs to be restarted or it won't work anymore.

The solution?

My router runs OpenWrt, so I am able to run a script that checks for external IP changes. When a change is detected, it uses SSH to connect to my server to restart jitsi
Because I don't want the router to just be able to run any command, I created a jitsi-restart user that has no shell
When the router tries to log in with its pubkey, sshd creates a file called restartasap in the jitsi folder and closes the connection
On the server, there's a systemd unit running a script as the jitsi user that periodically checks for that file, and if it exists it deletes it and restarts jitsi

I've been running this setup since mid 2020 and I expect this to continue until IPv6 becomes the norm.

I duct taped a Raspberry Pi to the back of a television once. Does that count?

I have an old laptop running some basic services.

I have taken it apart before to replace the hard drive with an SSD, but I never replaced the dead CMOS battery because you have to literally completely disassemble it to get at the battery.

So I have a cronjob that runs on startup to change the system clock to the right time-zone.

It just felt simpler than completely disassembling a hard-to-take-apart laptop.

I have a folder full of scripts tied to aliases that fix various things when they go wonky, and I've long since forgotten what any of them do. I just know if xxx app stops working, I type fix_xxx into the terminal and then it does a bunch of stuff and then it works again lol.

Also I have a bunch of aliases tied to common tasks, like e1 = reboot, e2 = shutdown etc. I have no idea where that habit came from.

Edit: ALSO, just the general mish-mash of apps. I won't have anything to do with Snaps, but the rest of it is an unholy combination of native apps, things from the AUR, flatpaks, Appimages, Docker containers and wine setups, mostly (but not all) in Bottles.

I had to use unity game engine for one of my assignments for school, but unity wouldn't generate files needed for the language server unless I set the code editor to vscode. I fixed this by creating a bash script with the path /usr/bin/code that opens neovim in konsole.

#!/usr/bin/env bash
konsole -e "nvim $@"

I'm using Gentoo with systemd and a customized kernel, and additionally I have the /usr partition LUKS encrypted. Because /usr is absolutely essential for systemd to function, I configured dracut to make a specially crafted initrd which activates the luks lvm and prompts for the password to decrypt and mount /usr on startup before systemd init tries to run.

About a year or two ago, some update to dracut or some other dependency (assumption) caused the dracut generated initrd's to kernel panic. After multiple days of troubleshooting, I discovered that just copying forward an older initrd in /boot and naming it to match the new kernel, e.g. initramfs-6.6.38-gentoo.img , allows the system to boot normally .

So, my Gentoo is booting a kernel 6.6.something with a ramdisk generated in the 5.9 kernel era. I am dreading the day when this behavior breaks and I can no longer update my kernel 😳

Had a Centos VM that kept slipping time. Every week it would loose about 30min. No amount of NTP syncing got the time correct until manual intervention.
Msp couldn't work it out, couldn't rebuild the server for infrastructure reasons, and only that server had the issue. The other 3 VMs on that host were fine.

Cron job on one server took it current time, sshed to the dodgy server and configured the correct time.

An old (now decommissioned) notebook of mine had a broken headphone jack. I didn't have BT headphones then. Audio output worked technically but the detection whether headphones were plugged in or not did no longer work.

I wrote a very short amixer script to force unmute the jack, set the volume to 50 or so percent and set the speaker volume to 0% but not "mute" state. I could then use my wired headphones again.

sssd didn’t work well with my company’s AD server, which would cause repeated authentication failures until I restarted sssd. I rigged up a bash script which would restart sssd any time xscreensaver logged an auth fail.

On my previous laptop, the trackpad had a bug that made it spam interrupts after waking up from sleep. It ruined battery life and basically kept one core at 100% permanently.

So I duct-taped a systemd script that unbound and bound the trackpad after each wake up.

#!/bin/sh
case "$1" in
        post)
                echo -n "i2c_designware.0" > /sys/bus/platform/drivers/i2c_designware/unbind
                echo -n "i2c_designware.0" > /sys/bus/platform/drivers/i2c_designware/bind
        ;;
esac

I ran out of crtcs, but I wanted another monitor. I widened a virtual display, and drew the left portion of it on one monitor, like regular. Then I had a crown job that would copy chunks of it into the frame buffer of a USB to DVI-d adapter. It could do 5 fps redrawing the whole screen, but I chose things to put there where it wouldn't matter too much. The only painful thing was arranging the windows on that monitor, with the mouse updating very infrequently, and routinely being drawn 2 or more places in the frame buffer.

Youtube doesn't seem to inhibit idle for me for some reason, so my screen would always turn off with swayidle while watching youtube videos. So I made my lockscreen script (which is called by swayidle)

if [ "$(playerctl status)" = "Playing" ]; then
    exit 0
else
    exec "/path/to/lockscreen/script"
fi

(lockscreen script was just swaylock called with a bunch of arguments)

Not super crazy compared to some of the things people are saying in the comments, but also definitely not how you're meant to handle idle inhibition when media is playing lol

I have a Logitech mouse with extra buttons, I used Piper to set one of those buttons to be Play/Pause media button. It worked well, however for some reason it only worked when the mouse was connected via the dongle, via Bluetooth the button did nothing. So I configured to a random shortcut (don't remember what it is now, something like super+p) and configured that to call playctl play/pause.

Not as creative or duct tapey as others but it's what I remember now, pretty sure there are many others too hahaha

holy shit i was about to post about how i have automatic login and lock to start a program that refuses to work correctly on boot through systemd.

but then you guys are here casually posting some of the worst duct tape shit ive heard of so far. im not sure if i should reprimand or congratulate you for that jankiness.

So I use a surface device with the Linux surface kernel, and there was (and probably still is) an issue where the type cover doesn't properly rebind after being detached and re-attatched. To make matters worse, connecting other USB devices disconnected the type cover. My solution was to make a udev rule that detected if the keyboard is "removed" and then try to rebind it, effectively unplugging it and plugging it back in again in software.

I made a systemd script that fires when going to / waking up from sleep - it checks how long the sleep was and if it was just a few seconds, it puts the computer back to sleep.

In hindsight, I think the thing that made it work was bluetooth was somehow responsible for the initial failed suspend. The second shot at sleep happened before bluetooth came back up, so it succeeded.

I have a hardware malfunction with my secondary hard drive. Every once in the while it locks itself into read-only mode and corrupts a log file that crashes my system. My solution is to reboot Fn + Alt + Sysrq + 'b' and periodically delete the log files that exacerbate the issue. I need to replace the drive but that requires money and a backup solution, neither of which i currently have. It's been an ongoing issue for at least 4 years now.

I regularly recommend configurations to peers that are arguably impossible for normal humans. (Not on purpose! Sorry Dave!)

I love to run stuff on Raspberry Pi, and I fear no gcc compile flag. (Ok. That's a bold faced lie, even I fear a couple of them.) So I frequently forget the bullshit I had to do to get something weird running on a random Pi.

Some years ago, I had a client with a really fucked up set of requirements:

Must run Gentoo Linux. (No, I don't know why. But it was written into the project specs and everybody who had to sign off did.)
Must use LUKS for FDE.
Login (loosely interpreted as "booting up") must have MFA.

This was during the days when booting into a LUKS encrypted Gentoo install involved copy-and-pasting a shell script out of the Gentoo wiki and adding it to the initrd. I want to say late 2006 or early 2007.

I remember creating a /boot partition, a tiny little LUKS partition (512 megs, at most) after it, and the rest of the drive was the LUKS encrypted root partition. The encrypted root partition had a randomly generated keyfile as its unlocker; it was symmetrically encrypted using gnupg and a passphrase before being stored in the tiny partition. The tiny partition had a passphrase to unlock it. gnupg was in the initrd. I think the workflow went something like this:

System boots up.
Script in the initrd prompted the user for the passphrase for the tiny LUKS partition. (first authentication step)
User entered passphrase.
Script in the initrd unlocked the tiny partition and prompted the user for the passphrase to decrypt the root partition's keyfile stored therein.
User entered the symmetric passphrase for keyfile. (second authentication step_
Script used the passphrase to decrypt the keyfile to stdout, piped into an evocation of cryptsetup to unlock the root partition.
/dev/mapper/root mounted, /boot mounted, boot process continued.
User logged into the box.

I don't miss those days.

Side of the case fell off.

For me it's probably the way I self-host overleaf, a online LaTeX editor. The community version has a docker image that's horribly maintained (because they want to sell enterprise, I reckon), and instead relies on a horrendous amalgamation of setup scripts that wrap docker compose.

What I have is a Dockerfile that pulls the image, manually installs a second version of TeX with the right dependencies, unlinks the old one and links the second one. Then for the database, it uses Mongo replsets, which be to be manually initialized. So I wrote a health check for the container that checks if the repl set is initialized, and if that fails the health check initializes it.

It's horrendous, it's disgusting, and it's an all-in-one compose file to get overleaf running. Good enough.

I've set Raspberry Pis to auto-reboot themselves at night if they are being used for headless network services that need to be available 24/7, just to clear out memory leaks or other things that may have gotten locked up. Not sure if that's duct tape or just a standard practice. They aren't the most stable things sometimes. They're known for power supply and SD card issues.

I created an SMS to Email gateway back in 2011 when data was still expensive on phones and I was trying to see if I could turn an iPod Touch into an iPhone. (I was a poor student at the time, was trying to find ways to save money 😅)

Basically I had a 3G modem plugged into a Linux server that could receive the messages, a prepaid SIM card with a long life credit expiry, a domain name set up with unknown email address capturing, and some tools to handle the actual SMS part.

At the time I published the scripts I used online and apparently they're still online 😅 This is on Whirlpool which is an Australian telecommunications forum.

Well it was more like a temporary duct tape, but I "installed" a copy of Ubuntu in RAM from the running Ubuntu system so that I could "boot" (pivot_root) into it without restarting it

All because I didn't want to wait on a ticket for my dedicated server provider to hook in a KVM LOL

(See my meme post I posted to c/linuxmemes a few weeks back for more info)

I keep a small local knowledge base with common fixes for problems I find recurrently (over and over again in some cases).

It has a bit over 1,300 lines of markdown files split by category of problem. It saves me the trouble of finding that exact solution in stack overflow that fixed this exact problem 5 months ago.

I one crossgraded a debian server from x86 to x86_64.

You guys will probably groan but lots of people in this comment section should look into NixOS. My old Ubuntu machine was loaded with hacks I got from stack overflow to get certain things working (a script that runs at boot and shutdown to mount and unmount some network drives I wanted to appear natively). But now, I just use NixOS and there’s nothing on my machines that is even remotely hackey now. I just declare the drives as I want them and when I boot they are there and work as needed.

Not me personally, but in one of my past project, my boss was running a bunch of "services" by leaving it on GNU screen terminal sessions and detaching from them.

Everytime I went in to debug something, I'd need to go thru a list of sessions, attach to one hoping that it's the right one (sometimes they'd name 'em), then see the console output.

Got fed up of Pipewire suspending (old receiver takes ~2 sec to work again after spdif stream is cut) that now I auto-run aplay to play a silent .wav on loop

Wow, Lotta smart people here doin some.hacky shit

I got an Orange Pi 5 Plus to play with smallish AIs (because it has an NPU) and I normally access it remotely, so I have to know its IP address to do it.

In order to easilly know the IP address of it, I've wired a little 128x64 monochrome OLED screen to it (Orange PIs, like Raspberry PIs have a pin connector giving access to GPIO and interfaces like I2C, Serial and SPI) which talks via I2C.

Turns out those interfactes aren't active in Linux by default (I.e. no /dev/i2c-x), so I figured out that I had to add a kernel overlay to activate that specific interface (unlike with the Raspberry PI whose Linux version has a neat program for doing it, in the Orange Pi you have to know how the low level details of activating those things), which I did.

To actually render characters on that screen I went with an ARM Linux port of a graphics library for those screens I used before with Arduino, called u8g2)

Then I made a program in C that just scans all network interfaces and prints their names and IP addresses on that screen, and installed it as a Cron job running once a minute.

Now, as it turns out when you shutdown your Linux on that board, if you don't disconnect it from power there is actually still power flowing through the pin connector to any devices you wire there, so after shutdown my screen would remain ON and showing the last thing I had put there, but because the OS was down it would naturally not get updated.

So the last thing I did was another small C program which just sends to that screen the command for it to go into power saving mode, shutting it down. This program was then installed as a Systemd Service to run when Linux is shutting down.

The result is now that there is a little screen hanging from the box were I put this board with Linux which lists its IP addresses and the info is updated if it connects other interfaces or reconnects and gets a new IP address. Curiously I've actually been using that feature because it's genuinely useful, not just a funny little project.

Prior to switching (upgrading?) to Wayland, Debian KDE crashed under X11 regularly when waking from hibernation and the taskbar would disappear. Restarting the plasma shell made it operable again, so I created an alias and regularly rebooted the DE shell 2-3x a day:

alias damnTaskbar='killall plasmashell ; kstart plasmashell &'

Building a custom Buildroot Linux for a Pentium 2 laptop that can fit on a CD so I could back up a 2.5" IDE drive to a USB drive, probably.

On another note, last night, I had to get a Google TV set up on my dorm Wi-Fi, which requires me to either go through a portal to set it up or to go into my account and add the device's MAC address. The TV (which was brand new and doing OOBE stuff) wouldn't let me go to settings to get the MAC address without a network connection. Even more infuriating, there was a button in the Google Home app that said "Show MAC address", but when I pushed it, it would say "Can't get MAC address." What I ended up doing to get around that crap was setting up my Debian Thinkpad (which I am writing from now) to share its internet connection over ethernet to finish the setup process so I could get to settings and get the MAC address.

On one hand, a funny experience, but on the other hand, I'm simultaneously both mad at Google and my dorm internet provider.

I had to upgrade some OL6 VMs to OL7 VMs running Oracle DBs and Apps (on OVMM no less). There was no appetite for buying additional storage, or restoring the environments with RMAN. Luckily, everything had been installed under /u01 which was on its own virtual disk.

So I built a new VM as OL7 (same hostname, etc.), installed the pre-req RPMs for Oracle DB, disconnected the virtual disk from the OL6 and attached it to the new OL7, synced users and home dirs - and it only bloody worked.

Had a zfs array on an adaptec raid card. On reboot the partition table would get trashed and block the zfs pool from coming up, but running fdisk against the disk would recover it from the backup.

Had a script to run on reboot that just ran "fdisk -l" on every disk, then brought up the zfs pool. Worked great for years until I finally did a kernel upgrade that resolved it.

I ran chmod 777 /dev/uinput so AntiMicroX worked on Wayland. The PC was intented to be used as an HTPC. A Dualshock 3 would be the remote and KDE Plasma Bigscreen would be used to launch Linux native apps ie. Firefox and Android apps via Waydroid, hence the Wayland requirement. AntiMicroX would bind gamepad inputs to arrow keys, enter, ESC, volume up/down, mouse navigation, left/right click etc. The whole setup was duct tape, user unfriendly and it ultimately did not solve the problem that sent me down this rabbit hole: Internet was unstable even with an ethernet cable so it had no advantage over the crappy Android TV stick that had trouble streaming anything but Chromecast. A close contender is having to disable Internet when launching a specific online only game otherwise performance halves. There is also a guide I uploaded to Reddit that describes how to import ringtones from Linux to iOS that has 8 steps and involves rebooting your phone. And another guide to run 2 games at once and stream one of thrm while playing the other locally.

I have a problem with half working duct tape solıtions.

I had an external hard drive enclosure that I stored my Plex content on before I built a nas, and the enclosure would go to sleep after 15 minutes and take the drives offline. So i had a cron script write a 1 kb file to each drive every 14 minutes. Worked well enough

I was trying to customize shit and accidentally deleted my entire task bar. I couldn't figure out how I did it so I just installed a different one which needed to boot on startup.

My Nvidia card won't properly resume the display after suspend with the default suspend script, but if I correct the script file, every time aptitude updates the nvidia drivers, it restores the bad version of the configuration file. If you set the file immutable with chattr, aptitude throws a fit and goes into a broken state when it can't overwrite the file on a driver update.

So I keep a good copy of the script file in the directory, and in my pre-suspend script file I overwrite the main suspend script with the good version. Every single time.

Couldn’t figure out how to access my headless server’s desktop environment via VNC without a monitor connected and turned on. I bought a hardware displayport dummy adapter to pretend to be a real display to get it to work.

A hardware solution to a software problem… felt really wrong.

I’ve since wrapped my head around tmux and managing all my services via command-line or web-ui so I have no need for it anymore.

I'm not technically inclined at all, so the most duct tapey thing I can remember was hacking Gnome to use Nemo as my file browser instead of Gnome's default file browser once.

not sure if duct tape or brute force but if I can't stop a file from getting overwritten like resolv.conf I just make it immutable with chattr

sometime ago I had my home directory managed by systemd-homed on Fedora (before 38 even afaik). the SELinux policy wasn't configured properly for it though, so I had to keep setting it to permissive mode. for some stupid reason I remember running the command to do that on every. single. boot. lol

Fixes the fucking clipboard in citrix, no, I cannot figure out a better solution.

the move to aquamarine with hyprland mostly resolved this... but not completely and i'm going to have to write a new duct tape solution for that.

If you're wondering why I launch alacritty... it doesn't work without alacritty, wayland needs the window to be in focus, if alacritty isn't there there's no in focus window and it doesn't update the clipboard.

Not exactly mine but I've used it. I have a fast but data-limited internet connection and a slower unlimited connection. When I need the faster connection to do something I connect to it through wifi while staying connected to the other through Ethernet. Then use this project to bind a specific app to wifi while everything else keeps using Ethernet. It uses LD_PRELOAD to link its own version of network connect that calls the real method. There's definitely a better way to do this with iptables but it's a good enough patch for when needed.

I'm rebooting my router every week via a crontab because some dynamic dns update process fails from time to time and I find it hanging. No time to debug the actual problem.

Actually really few instances of jerry rigging, but I do remember during my distro-hopping days where I used a binary gcc package to compile a more optimized binary of gcc. At the time, that felt pretty weird, but looking back I see why.

Possibly my light/dark mode scripts. They change my Plasma theme, which is honestly most of the job, but also set the matching GTK theme, set the new theme in running Konsole sessions, do a bunch of manual sed edits on conf files for applications that don't follow system theming, finally restarting plasmashell to clean up the occasional edge case where a tray icon is supposed to follow the theme but doesn't.

something kept messing with my dns and i’m too lazy to find out why so i hardcoded etc/resolv.conf and chmod +i on it

Did a physical-to-virtual-to-physical conversion to upgrade and unbreak a webserver that had been messed up by simultaneously installing packages from Debian and Ubuntu.

I wrote a systemd unit file to force my wireless keyboard to always switch the fn key to normal F-keys.

I really needed to run a compositor from an arch chroot and systemd's udev is straight up broken in chroot, so I used libudev-zero and made sure that every time systemd updated I would delete the libudev .so file and plunk libudev-zero ontop of it, no i've moved on to greener pastures (Artix) but hey, it did work.

I used to have a bug with my KVM switch muting my audio devices when I switch. Tried so many things but ended up running a login script that continuously runs unmute command on loop every 100ms.

I wrote a script to turn the power of the the Wifi+Bluetooth chip off, then enumerate the PCIe bus again to start it back up.

The chip sometimes hung itself when using both. I looked for the bug and even found an Intel engineer on some mailing list admitting that they had issues with coexistance mode.

Just turning the wireless off and back on wasn't enough I needed to reeinitialize the hardware and that was the best way I knew.

It makes me mad to see the current state sway is in, I even bought an AMD GPU for nothing.

In the earlier days of Plasma 6, it would crash on me when waking from sleep, so I had a small script that would basically restart plasmashell when waking so I didn't have to wait the several seconds for the system to realize that it was frozen before I had a functional desktop.

On the client side of a relayd-based wireless bridge using OpenWrt, I discovered there was a bug in that relayd version which made the process hang after it moved so many gigs of data. I made a cron job that pings the network relayd makes accessible. If the ping fails, it nukes relayd. Of course this relies on a live machine to ping. If this machine dies for some reason, the cron job would just keep killing relayd over and over again. 🥹

gtk3-classic still doesn't work properly on Wayland and I doubt it will ever be fixed so I include WAYLAND_DISPLAY=0 in each shortcut file to force them into xwayland.

Bootstraping.

This is in my Home Manager configuration. I don't think this is that bad, it's just kinda messy. If you can't tell, it's a script for taking screenshots, embedded in my configuration.

I made a script to add a middle click scroll function with a toggle. I can share the script, it's a really bash script

God my current setup is patched together and hanging by a thread. Not super tech savvy so it usually takes a dedicated deep dive for me to set everything up (and all the focus and motivation that entails). So if something goes wrong while I'm trying to work, I'm more likely to find a quick workaround and make a note to fix things later.

Except five years later I haven't truly fixed anything lmao. Gonna just do a clean install one of these days, if I can decide on a distro.

Don't remember the specifics but I had a key combo setup to force a soft reset in my DE. Occasionally a kernel or driver update would fuck up my video and make the system unusable but still live. I try to avoid hard resets.

Here's a few of the micro-hacks that I've hacked up in the past.

A 2-line script to chroot into Debian when logging in as a certain user on FreeBSD.

#!/bin/sh  

clear  
doas chroot /linux /bin/login

I didn't have an IDE, so I just made a script called ```ide``` which runs Vim, and then compiles the code and makes it executable.

This thing, called ```demoronize```, which does what it says in the comments

#Convert DOS line endings to Unix ones and add a final newline if there isn't one,

#and replace "smart" quotes with normal ones

I just keep those ones for historical value, but there's one hack I use every day. My keyboard doesn't have a function key (Fn), so I use the Super/Windows key instead.
I have xdotool keyup Super_L keyup Super_R keyup F4 key XF86Sleep bound to a custom keyboard shortcut. It unpresses the keys used for the shortcut (Super + F4), then presses the sleep key.

About a decade ago I was playing a game on Linux and the game crashed and took the entire DE with it. So I went to a different tty and started a fresh x desktop session and started playing again until the game crashed again (I was running a bunch of mods so it would crash every couple of hours or so) and still didn't feel like rebooting so I went to yet another tty and started yet another x desktop session. I did this about 3 times in total before I finally went "I should probably actually reboot because this has to be making a bigger mess of things"

I converted a custom raspberry pi distribution (some kind of a debian I think) into an Arch Linux ARM without a reinstall.

I’ll leave this one here for someone:

You can tunnel L2 over OpenVPN. Just bridge your interfaces in both sides and it works.

That way if you need to provision a VOIP phone or just have something NetBoot remotely. Not that I recommend doing that…

When installing an encrypted Arch system, I couldn't figure out how to change the keymap in GRUB stage 1, which asks for the passphrase and then decrypts /boot. I just entered my passphrase with the default en-us keymap without really knowing what characters it outputs.

Hmm. Maybe systemctl enable rc-local because I was too lazy to get the service order correct and I just wanted something to happen last and be done with it.
