foogod, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .
If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report: apport-collect -p linux <replace-with-bug-number> Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the kernel in the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested and remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream-VERSION-NUMBER', where VERSION-NUMBER is the version number of the kernel you tested. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream-VERSION-NUMBER', where VERSION-NUMBER is the version number of the kernel you tested. If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the tag: 'kernel-unable- to-test-upstream'. Please let us know your results. Thank you for your understanding.

It works fine if I boot up with the monitor connected, but if I start without it and then plug it in while the X server is running, it completely locks up X. When I remove the monitor, X starts working again and I can continue as if nothing had happened. I have tested things while only running a basic X server/xterm and the problem still happens as soon as the monitor is plugged in. I have tested the following scenarios: X running --> plug-in monitor = freeze X running --> plug-in monitor --> (freeze) --> unplug monitor = unfreezes X stopped --> plug-in monitor = works (monitor mirrors text console) X stopped --> plug-in monitor --> start X = works (mirroring/separate/different resolutions/etc all work fine via gnome settings) (freeze) --> unplug --> (unfreeze) --> stop X --> plug-in --> start X = works (freeze/unfreeze does not appear to have any lasting effects on behavior) - Please let me know if there's any additional info I can provide that - would be of assistance. + WORKAROUND: I do not encounter the lockup if I connect the monitor to + the DisplayPort using a passive DP->DVI (pass-through) adapter, it only + seems to occur when using the native DisplayPort output mode + (unfortunately, however, the passive DVI adapter cannot support my + monitor's full resolution) ProblemType: Bug DistroRelease: Ubuntu 11.10 Package: xorg 1:7.6+7ubuntu7 ProcVersionSignature: Ubuntu 3.0.0-14.23-generic 3.0.9 Uname: Linux 3.0.0-14-generic i686 NonfreeKernelModules: wl .tmp.unity.support.test.0: - + ApportVersion: 1.23-0ubuntu4 Architecture: i386 CompizPlugins: [core,bailer,detection,composite,opengl,decor,imgpng,snap,move,compiztoolbox,resize,gnomecompat,regex,mousepoll,vpswitch,unitymtgrabhandles,grid,place,session,animation,wall,workarounds,expo,fade,scale,ezoom,unityshell] CompositorRunning: None Date: Thu Dec 15 16:25:42 2011 DistUpgraded: Fresh install DistroCodename: oneiric DistroVariant: ubuntu DkmsStatus: - bcmwl, 5.100.82.38+bdcom, 3.0.0-12-generic, i686: installed - bcmwl, 5.100.82.38+bdcom, 3.0.0-13-generic, i686: installed - bcmwl, 5.100.82.38+bdcom, 3.0.0-14-generic, i686: installed + bcmwl, 5.100.82.38+bdcom, 3.0.0-12-generic, i686: installed + bcmwl, 5.100.82.38+bdcom, 3.0.0-13-generic, i686: installed + bcmwl, 5.100.82.38+bdcom, 3.0.0-14-generic, i686: installed ExtraDebuggingInterest: Yes, whatever it takes to get this fixed in Ubuntu GpuHangFrequency: I don't know GpuHangReproducibility: Yes, I can easily reproduce it GpuHangStarted: Today GraphicsCard: - Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller [8086:2a42] (rev 07) (prog-if 00 [VGA controller]) - Subsystem: Dell Device [1028:0233] - Subsystem: Dell Device [1028:0233] + Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller [8086:2a42] (rev 07) (prog-if 00 [VGA controller]) + Subsystem: Dell Device [1028:0233] + Subsystem: Dell Device [1028:0233] InstallationMedia: Ubuntu 11.10 "Oneiric Ocelot" - Release i386 (20111012) MachineType: Dell Inc.
