After installing the official ATI linux drivers (Gmod gave an “OpenGL outdated” error with the default fglrx packages on Ubuntu 12.04), gmod ran and loaded a map with no problems at all with all my addons enabled, which was pretty astonishing. But then the AA was disabled so I tried to set it up to 2x and it froze, now when I start gmod I get a steam popup box with an error message that says:
And then I press “OK” and it closes. I’ve tried what’s on the steam page to no avail, so how do I disable anti aliasing in the config/config.cfg or with the launch options? I’ve tried clearing my addons folder, deleting my config folder, verifying game cache, putting mat_antialias “0” and mat_aaquality “0” into the config.cfg, putting -dxlevel 81 in the launch options and using the dev branch with no effect. There are no .mdmp files anywhere.
Sorry if this is the wrong forum.
