Possible bug in plasma 6.2.5 Wayland with nvidia 550.144.03 and GLX_VENDOR_LIBRARY_NAME profile

Help

Hi !
I’m not sure where I should post this, but I’ve experienced and solved what looks like a recent bug touching my opensuse Tumbleweed installation.

I did a zypper dup saturday 01/18 which installed the 550.144.03-30.1 version of nvidia G06 driver. After rebooting, I have not been able to start plasma wayland with my default user (SDDM → black screen for a few seconds → SDDM).

But Gnome wayland was working seemlessy, and plasma X11 too. The other weird behaviour was that I was able to launch plasma wayland for any new user I could create. But deleting all plasma configuration files for my main user didn’t change anything.

After having tried many options, I finally found that I was able to launch a plasma session after deleting the .profile file and all the /run/user processes for this user. Trying to fine-tune this solution, I’ve found 2 lines in .profile, that I might have added a long time ago while fine-tuning my wayland installation (that’s old…) :
export GBM_BACKEND=nvidia-drm
export __GLX_VENDOR_LIBRARY_NAME=nvidia

Putting a # before the second one solved the problem. Any attempt to get it back caused the bug again.

So it looks like something between plasma and this nvidia driver (and maybe only the opensuse Package) have stopped handling correctly the GLX_VENDOR_LIBRARY_NAME

I could track this as a bug but I’m not really able to diagnose more and I’m not sure if i belongs to plasma, nvidia or opensuse… Maybe someone here will be able to test it and tell me ?

Thanks :slight_smile:

Hi lc_lol.

I’m on Tumbleweed here.

What are you trying to achieve by setting this variable? It seems like if you added it and it broke stuff, then you shouldn’t add it :wink:

I had it in my profile too, and it caused problems too, so I removed it (not related to your update, this was a long time ago).

Hi pallaswept :slight_smile:

Thanks for your kind answear.

I’ve got rid of these variables, can’t remember how and why they were put there (certainly by myself, but that was almost three years ago). The only info about it in my .profile file is a comment saying “# Tweaks mostly from: [archlinux wiki page about wayland]”

Glad to see they’re not useful anymore. I also posted because I thought that someone could get the same problem. Maybe this post will help them solving it :slight_smile:
