** Description changed: - Used Precise for weeks, with external monitor sometimes plugged, everything ok. - (Small drawback: boot fails with external monitor attached. Another issue.) + After batch software update on 2011-05-21, X started to freeze (as + defined on https://wiki.ubuntu.com/X/Troubleshooting/Freeze ) within + minutes when running with an external monitor attached (desktop extends + on both laptop LCD and monitor via VGA output). - Today I applied system update. + In the meantime, I observed that the freeze also occurs without external + monitor attached but with a much higher delay, say a few times per + month. - Now, whenever I plug in external monitor, desktop extends correctly on it. - After a moment (minutes), the bug happens. + Per https://wiki.ubuntu.com/X/Troubleshooting/Freeze : - * Mouse pointer moves but... - * Clicking anywhere does nothing. - * *No* update anywhere on screen (e.g. no more CPU activity graph scrolling every second) - * Music from X client rhythmbox continues playing for about a minute or so then stops. - * Ctrl-Alt-F1 does not switch to text console - * Ssh into machine works. Killing some X clients does not change display. + > Have you experienced just one lockup, or have you had a series of + these lockups? - One of the times, to get back control of the laptop screen, I had no choice but reboot. - The last time, killall Xorg succeeded (a new Xorg was launched by lightdm) and I'm using that session while typing this. + A series. - Bug happens reproductibly a while after external monitor plugged. - *Does not happen when external monitor is not plugged.* + > If you've had several, how often does it occur? Every few + hours? Once or twice a day? Couple times a week? + + With external monitor, within minutes. + Without external monitor, within weeks. + + > When did you first notice it? + > Shortly after upgrading? + > After updating? + + 2012-05-21, hours after an upgrade, when plugging an external monitor + (had not done that for a week or a few weeks, but had definitely done + that in the past with 12.04 without this problem). + + > After changing compositing (Desktop Effects) settings? + + No, compositing is disabled at all times. + + > Under what conditions does it seem most likely to reproduce? (...) + > When changing resolution or enabling/disabling monitors + + With external monitor, within minutes. + Without external monitor, within weeks. - ##### History - - * I'm not definitely sure that the bug was technically triggered by the update today, but - * the problem definitely never happened before today. - - * I applied software update on 13h14m. - * First bug occurrence at about 16h07m. - * Second bug occurrence at about 16h14m. - * Third bug occurrence at about 17h10m. - - (then used machine on battery without external screen until out of - energy) ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: xorg 1:7.6+12ubuntu1 ProcVersionSignature: Ubuntu 3.2.0-24.37-generic 3.2.14 Uname: Linux 3.2.0-24-generic x86_64 .tmp.unity.support.test.0: - + ApportVersion: 2.0.1-0ubuntu7 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 Date: Mon May 21 18:46:13 2012 DistUpgraded: Fresh install DistroCodename: precise DistroVariant: ubuntu ExtraDebuggingInterest: Yes, if not too technical GpuHangFrequency: Several times a day GpuHangReproducibility: Occurs more often under certain circumstances GpuHangStarted: Today GraphicsCard: - Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0116] (rev 09) (prog-if 00 [VGA controller]) - Subsystem: ASUSTeK Computer Inc.
