I just switched to Pop OS, any tips on what I should do next?

I’ve installed Pop!_OS on many machines over the years, and my standard process is:

• Install PopOS
  • rare for PopOS, but, depending on specialized hardware (some legacy Nvidia cards), a little driver rejiggering might be called for. Or a weird network printer setup that CUPS doesn’t like.
• sudo apt update && sudo apt install -y apt-fast && sudo apt -y upgrade
  • pee, smoke weed, feed kitty…
• set up my custom zsh/bash profile for the terminal
• enable firewall
• configure SSH and whichever remote management tools I need (I happen to deploy remote machines frequently)
• sudo apt install gnome-tweaks & a few other UI tweaking tools (obviously, this step will no longer exist soon)
• tweak UI/UX
• search through gnome extensions website for extension I want to install. There’s usually a Top 10 or Top 20 gnome extensions list you can google (eg: “best gnome extensions 2024”)
• make sure I have all appropriate media codecs installed and updated.
• set up pip-/pip3-installer.

After that, it’s setting up/configuring whatever software that particular machine needs.

Edit: there’s probably a lot that I’ve skipped/missed, and a lot that others will do along their way through these steps. This is just a basic outline of some of my post-install processes (developed over time), and I hope this answers your question.

Also, you can google for post-install guides for Ubuntu and they’ll largely be applicable to PopOS since it’s based on Ubuntu.
