Hello @Galaxy0419, does any 32 bit opengl application like glxinfo32 from lib32-mesa-demos work? Swrast is mesa's slower software renderer, and the fact steam is trying to use it hints that you're trying to use mesa's libGL.so with the nvidia proprietary driver, which is incompatible. Please check if lib32-nvidia-390xx-utils is installed on your system.
Installing lib32-nvidia-390xx-utils solves the issue.
So Ubuntu Steam is only compatible with 32-bit driver and applications?
Nothing extracted yet.
