** Description changed: - I've looked at the page at - https://wiki.ubuntu.com/X/Troubleshooting/Freeze and can reproduce the - bug at will by entering the command + I've got Xorg freezes from time to time. Previously, I was able to + reproduce it with sleep 1; xset s activate - that's mentioned on the page. The freeze occurs when the screen content - reappears after moving the cursor. Cursor is still movable but clicking - has no effect. + as described at https://wiki.ubuntu.com/X/Troubleshooting/Freeze . + That's no longer possible. + + However, freezes happen from time to time when I try to use the computer + after the screen has been deactivated. + + I suspect it's a kernel problem because changing the kernel makes a difference: + - on some kernels it doesn't seem to occur at all (e.g. 4.0.3 from mainline-crack) or the frequency is just so low that I haven't seen it yet + - on newer kernels (e.g. 4.5 rc* and later, including the 4.5 release), the system restores the screen but Xorg freezes up almost instantly afterwards + - on some kernels, the system doesn't properly restore the screen, there's a pattern with stripes or a single color (e.g. 4.0.4 from mainline-crack) ProblemType: Bug DistroRelease: Ubuntu 15.10 Package: xorg 1:7.7+7ubuntu4 ProcVersionSignature: Ubuntu 4.2.0-25.30-generic 4.2.6 Uname: Linux 4.2.0-25-generic x86_64 .tmp.unity.support.test.0: - + ApportVersion: 2.19.1-0ubuntu5 Architecture: amd64 CompizPlugins: [core,composite,opengl,compiztoolbox,decor,vpswitch,snap,mousepoll,resize,place,move,wall,grid,regex,imgpng,session,gnomecompat,animation,fade,workarounds,scale,expo,ezoom] CompositorRunning: None CurrentDesktop: XFCE Date: Wed Jan 27 21:37:53 2016 DistUpgraded: 2016-01-11 19:25:27,198 ERROR got error from PostInstallScript ./xorg_fix_proprietary.py (g-exec-error-quark: Failed to execute child process "./xorg_fix_proprietary.py" (No such file or directory) (8)) DistroCodename: wily DistroVariant: ubuntu ExtraDebuggingInterest: Yes, including running git bisection searches GpuHangFrequency: Several times a week GpuHangReproducibility: Yes, I can easily reproduce it GpuHangStarted: Immediately after installing this version of Ubuntu GraphicsCard: - Advanced Micro Devices, Inc.
