Yeah, you have Vulkan and Mesa and the GPU drivers are in the kernel. That’s the whole stack (along with Proton).
Before reinstalling completely, run a full system upgrade, I took this from system76s support page:
sudo apt update
# configure any packages partially setup
sudo dpkg --configure -a
# fix any missing package dependency
sudo apt install -f
# upgrade all packages and dependencies to newest in release
sudo apt full-upgrade
# make sure the `pop-desktop` meta package is installed
sudo apt install pop-desktop
You’re also likely using some flatpak applications, so:
flatpak update
Then reboot.
They want you to reinstall because walking you through a fresh install is just more time efficient for their support staff than trying to troubleshoot system configuration problems (imagine the possible things a random user could change x.x).
Dude, the number of times I’ve resorted to a reinstall are innumerable. You know a bit more than you did yesterday and that isn’t nothing.
If you want to try a new project that’ll need tinkering with (but won’t break your existing install) look at gamescope.
Currently it’s the only way to get HDR and variable refresh rate to work. It’s what Valve made to get those features into the Steamdeck.
You just run it with
In your steam launch options. You’ll need to look up the options (otherwise it defaults to 720p@60hz). Ex:
For 4k. There’s a switch for HDR too but I don’t remember it without looking it up. You can use gamescope to enable FSR in any game, it can apply reshade shaders (so, things like anti aliasing in games that don’t have it natively).
Other than that, any issues you have with a particular game can usually be solved by looking at protondb.com
Keep using the GE-Proton builds of proton for best results.
Have fun 🤓
