Sounds like a video driver problem. Are you using one of the proprietary video drivers (ati-drivers, nvidia-drivers, etc)? If yes, you could try: #eselect opengl list Available OpenGL implementations: [1] ati * [2] xorg-x11 My ati-drivers need the proprietary version of opengl and sometimes this setting is wrong after updating the opensource mesa package. Otherwise I'd just try re-emerging your video drivers as an experiment :)
