What's the best light desktop env to install in a Linux distro?

I usually go with Xfce.

@Crying4625 If you don't mind use Xorg, go with XFCE
I personally prefer LXQT, specially since Wayland development is already work in progress

PSA no matter how light your distro, any modern app or webpage will use all that power

That's fast enough to run the latest Linux Mint with Cinnamon. I have two laptops with the exact same cpu speed (passmark score) and 4 GB of ram. With 2 GB swap file you will be in business.

I'm running Kubuntu on less than that on a desktop and it works just fine.

If you are still using X, get Fluxbox, very lightweight, requires some config, but that is fairly easy.

If you don’t need a full desktop environment, check-out IceWM.

I recently checked-out Trinity ( essentially KDE 3 modernized ) and was surprised how decent it was. I used it in Q4OS but it may be available in your distro.

LXQt, XFCE Or a window manager, they’re all lightweight.

• the big guns: Gnome or Plasma
• the middle tier: Xfce or LXQt
• the lightweights: tiling window managers (and there’s a LOT to choose from)
• the alternative crowd: Mate, Cinnamon, Regolith

Technically not a DE, but I like plain openbox.

Its fairly difficult to find "up-to-date" performance / RAM comparisons of Linux Desktop environments, but here's a decent one from 2019 comparing memory usage of different Ubuntu flavors.

The most surprising thing is that despite KDE Plasma's reputation as being more ram-hungry, it actually used less ram than XFCE, meaning its developers have been making performance a focus.

A window manager like i3 or Openbox. If you are curious what that's like, then try out Bunsenlab Linux. (XFWM4 is also a great choice, but it requires some know how to properly rip out the rest of Xfce, like the relatively heavy desktop and the panel)

Does Xfce count as light? It's got plenty of features. Should fit in 4gb well enough though.

I love OB with tint2 and conky , no de needed.

Xfce

Does not answer your question, and someone already mentioned it in a thread, but don't forget zram when only 4GBs are available.

Moksha Desktop environment Bodhi Linux

I have a thumb drive with Mint Mate installed on it and it runs fine on a 4gb i5 - 3rd gen.

There are many options, but I'd say on those specs anything will run more or less fine with some tweaks/settings.

Personally I would go with KDE Plasma, because I feel most comfortable with it. It can be pretty light on system ressources when configured properly. Disable all the visual stuff (animations, blur, anti aliasing) and some of it's background modules (baloo and some other stuff that you personally don't need).

But you should take the one you are familiar with and find out how you can tweak it to be more light. Cheers

XFCE or LxQT but i have a preference for XFCE if it is for normal use.

I would go mx linux fluxbox

I'd go with XFCE

Probably lxqt. https://lxqt-project.org/ Very lightweight yet a full-on DE (minus bells and whistles). Found on most Linux distros repositories.

For something with that little memory, I would use a minimal window manager; you'll want every megabyte of memory if you want to have any chance at running something like a javascript-capable browser without constantly hammering swap. fvwm, cwm, jwm, and ratpoison are all small window managers I enjoy; but do your own research into what window manager is the best for you.

Your biggest problem is going to be the 4 GB of RAM. Saving a few hundred megs on the DE will help but not much. If you run a web browser ( and I cannot imagine using a computer without one ) that RAM is going to fill up fast.

Honestly, I would use a 32 bit distro on that hardware.

Q4OS with Trinity, Antix, Adelie, and DSL are all pretty decent options.

KDE plasma. From my experience it uses less resources than lxqt and xfce and works out of the box while lxqt and xfce required extra work to get wifi, screen brightness controls and audio working. I can have 10+ tabs in a chromium based browser open without lag on an old laptop with 2GB ram and 1.33 - 1.83GHz 4 core intel atom from 10 years ago.

Xfce, LXQt or just install JWM and enjoy the 30 Mb idle RAM usage

honestly they are all pretty good at this point. start with the default ur distro supports. if that isn't to your taste try kde/plasma, gnome or lxde

Is the A6 from 2017/18? Should be fine with anything. My wife's laptop is from 2010/11. I tried all the DEs because of the lightness claims, I found GNOME worked the best, and it is super peppy running NixOS.

I asked online why GNOME would perform better than what is assumed a lighter DE, and a comouter dude says GNOME goes and gets everything it needs and caches it when you launch something so retrieval is faster in the app, KDE loads stuff on demand as it is asked for so a alow CPU and HDD hinderes KDE for me.

if you can afford it, by 4 more gigs of RAM

LXQt, XFCE, Maté, TDE. Any of them will do. Which you choose depends on personal preference and how large an ecosystem you want—LXQt has only a few basic applications, TDE has pretty much everything that was in KDE3, the others are somewhere in between.

You could try Niri. I have tested it with a ~10 year old notebook with a 1st gen Core i5 cpu.

But, even newest Gnome runs smooth on this machine.

That's a reasonable machine. You probably could use anything but if you want lighter weight you could use Xfce4. If it is a laptop you could use stock gnome with some swap as a backup to prevent OOM

In my experiments with a similar setup and integrated graphics, full-wayland Kubuntu feels much more responsive than Xorg-Lubuntu, for what it's worth

Moksha Heck, just install Bodhi Linux 7, your choice between Ubuntu based or Debian based.

river or sway

If the PC has an SSD, install anything you want, the PC will handle it fine.

Ironically, ChromeOS Flex would run smooth on those specs, since it does so on my dogshit Samsung Chromebook 3 with shittier specs.
