Hello @kordax, the NVIDIA proprietary driver requires that the that the video driver's running kernel module, 32 bit userspace libraries, and 64 bit userspace libraries are all installed and exactly the same version to work properly.
Your system information tells us that your system is configured to run X on the NVIDIA proprietary driver, but you have no 32 bit userspace libraries installed for the NVIDIA proprietary driver. That is also causing Steam to fallback to llvmpipe (mesa's faster CPU renderer) for it to run at all.
On Ubuntu, this is generally found in the libnvidia-gl-525:i386 system package for the 525 series NVIDIA driver.
Closing because this is a system config issue, not a Proton issue.
Thank you for your assistance, btw, how did you figure out that it's falling back to LVM?
Compatibility Report
All games don't work.
System Information
I confirm:
Symptoms
None of the games work anymore after updating, looks like the NVIDIA driver messed up the display mapping/vdpau library.
Everything worked previously before manually installing 525.89.02
Tried to reinstall all the drivers, and check debsums of the packages.
Reproduction
Checking vulkan output gives me this:
~/.local/share/Steam/ubuntu12_32/steam-runtime/usr/libexec/steam-runtime-tools-0/x86_64-linux-gnu-check-vulkan
va-api also fails with error, but not sure if it should affect my games:
~/.local/share/Steam/ubuntu12_32/steam-runtime/usr/libexec/steam-runtime-tools-0/x86_64-linux-gnu-check-va-api
Any help is appreciated.
