For an example see http://askubuntu.com/questions/310161/broken-graphics- after-suspend-resume I have had this issue ever since changing from the closed source fglrx driver to the open source driver in 12.04, and it's still present in 13.10. I've also reported the issue with the xf86-video-ati maintainers, but I haven't been able to solve the problem yet. https://bugs.freedesktop.org/show_bug.cgi?id=70735 My version of package xserver-xorg-video-ati is 1:7.2.0-0ubuntu10 ProblemType: Bug DistroRelease: Ubuntu 13.10 Package: xorg 1:7.7+1ubuntu6 ProcVersionSignature: Ubuntu 3.11.0-14.21-generic 3.11.7 Uname: Linux 3.11.0-14-generic x86_64 NonfreeKernelModules: wl .tmp.unity.support.test.0: ApportVersion: 2.12.5-0ubuntu2.1 Architecture: amd64 CompizPlugins: [core,composite,opengl,compiztoolbox,decor,vpswitch,snap,mousepoll,resize,place,move,wall,grid,regex,imgpng,session,gnomecompat,animation,fade,unitymtgrabhandles,workarounds,scale,expo,ezoom,unityshell] CompositorRunning: compiz CompositorUnredirectDriverBlacklist: '(nouveau|Intel).*Mesa 8.0' CompositorUnredirectFSW: true Date: Wed Jan 8 14:23:09 2014 DistUpgraded: Fresh install DistroCodename: saucy DistroVariant: ubuntu DkmsStatus: bcmwl, 6.30.223.141+bdcom, 3.11.0-12-generic, x86_64: installed bcmwl, 6.30.223.141+bdcom, 3.11.0-13-generic, x86_64: installed bcmwl, 6.30.223.141+bdcom, 3.11.0-14-generic, x86_64: installed virtualbox, 4.2.16, 3.11.0-14-generic, x86_64: installed DpkgLog: ExtraDebuggingInterest: Yes GraphicsCard: Advanced Micro Devices, Inc.
