Black screen when starting Portal (or any HL2 game) on Linux
I've recently started having probs with Portal, HL2 etc. On launch, all I get is a black screen. I've seen loads of posts about this issue from a couple of months ago, and solutions then seem to stem back to video drivers.
openSUSE 12.3 64 bit with KDE4.10 with OpenGL compositing (not XRender)
Kernel = 3.7.10-1.16-desktop
Video = nvidia 660Ti, using proprietary drivers version 319.32 - verified that the drivers are in use, and Nouveau is blacklisted/not running
Other OpenGL based games launch fine, and Portal/HL2 was working 100% up until recently.
I have completely removed all Steam files,config files, and reinstalled from scratch with no change in results.
I've created a brand new user and started Steam under the new user with no change in results.
So... now what? Any suggestions?
