Hello @stuartlangridge, can you verify that any 32 bit opengl application like glxinfo from mesa-utils:i386 works?
@kisak-valve I can't test that specific example (because installing mesa-utils:i386 will remove mesa-utils and mate-tweak), but I've tried running the i386 version of a game (not from Steam; TheMaitreD, built with Unity), and that worked fine (as did its x86_64 version).
After a reboot, this problem seems to have resolved itself; I appreciate that this isn't very helpful, though. I'll close this issue, but if there's any more information I can provide then do reopen it and I'll try to.
Your system information
steam-launcher deb 1.0.0.52
Ubuntu 18.04
I'm not sure. I'm in the beta to get Proton, but I don't know if that's the client beta
Yes
Please describe your issue in as much detail as possible:
Launching steam from the command line prints an error and exits:
I've tried moving
pinned_libsout of the way, as per @kisak-valve's suggestion in https://github.com/ValveSoftware/steam-for-linux/issues/5463, but it didn't help.
