Created attachment 74957 [details] lspci, xorg log and glxinfo With my VTX3D Radeon HD 6570 card the entire screen content is corrupted, see the images and video. The proprietary AMD driver works fine. This problem is nothing new, I've seen it since I got the card with Ubuntu 12.04, 12.10 and now 13.04 (+xorg-edgers-ppa). http://steve-m.de/pics/radeon_artifacts.png http://steve-m.de/pics/radeon_corruption.ogv Also see the attached logfiles.
