I've been using PopOS for a few months now, and I'm interested in Arch, but I'm worried about whether or not I have enough experience to do that successfully. Also, I have an Nvidia GPU until I start a new build in the next year or so. I don't know if that'll be a problem in Arch. It was a major issue with Fedora for me.
I'm willing to learn the terminal, but right now I'm still pretty dependent on tutorials to do more than basic things, like installing software. Most of those are catered to Ubuntu-based distros, so I'm concerned I won't have the luxury of guides to more complex terminal stuff.
Am I overthinking this? Or should I wait longer (maybe even until I build a new PC)?
How difficult is the transition from Ubuntu-based to Arch?
Installation is a breeze with archinstall and the wiki makes most tinkering/ problem solving fairly easy. Having used mint and Ubuntu for a short time previously, I personally find it easier to tinker in arch than either of them.
Archinstall should offer installing the proprietary drivers once it detects your gpu. Other nvidia gpu problems depend on your de/wm choice. I use Wayland on kde with an Nvidia gpu and the biggest problem I have is some xwayland windows flickering, other than that it's just small nuisances.
For installing and updating packages get yourself an aur wrapper and enable the optional repos.
