OS Update: Ubuntu 20.04 → 22.04

Hello! I have recently updated my OS in hopes to get this issue solved. The results are... well, the same. Updating my Operating System did not change the error at all; I still get a Errror 303. I have tried using non-beta SteamVR, linux v_1.14 SteamVR, and also have tried forcing Photon Experimental with no avail.

Here is what my screen looks like today:

...And here are my updated OS information (the kernel, drivers should be the same)

System Information

• Distribution: Ubuntu 22.04.1 LTS (Jammy Jellyfish) ←updated
• SteamVR version: beta 1.25.2 ←updated

↑¿what the... for some reason, this command no longer outputs wrong ELF class: ELFCLASS32 Error.

After a while of tweaking, it seems that every time I unplug and replug the tethering cable together, SteamVR would always give me a Error -203. And when I restart headset, the Error will go back to 303.

Error 303

Removing the word "beta" because I have tested on non-beta SteamVR as well as non-beta Proton experimental with the same problem.

I have the same issue with steamvr beta 2.1.7: https://github.com/ValveSoftware/SteamVR-for-Linux/issues/639#issuecomment-1826775962 (that post contains a temporary workaround)

Just throwing this out there, do you have the DRI3 extension enabled?

$ xdpyinfo
...
number of extensions:    28
...
    DRI2
    DRI3  ← need this
...

The amdgpu xorg driver silently disables it if the mesa libraries don't match the ones it was built with exactly. Well, not exactly silently, it does log a message in your xorg log file, but good luck noticing that.

Without DRI3, SteamVR gives all sort of strange and variable error messages.

Works in SteamVR 2.1.8 :) https://github.com/ValveSoftware/SteamVR-for-Linux/issues/553#issuecomment-1833110353 , I have DRI3 but I had the issue at the time I posted it.
