Public bug reported: I had a crash last Monday on Xubuntu 12.04.1 LTS. It happened after browsing with Firefox for some hours IIRC. I did a kernel update from linux-image-3.2.0-29-generic:amd64 to linux-image-3.2.0-33-generic:amd64 the previous Thursday, so it might have been introduced then.
The mouse pointer was movable, everything else was still, clicking had no effect, keyboard had no effect (e.g. tried ctrl+alt+f1, I didn't know about alt+sysrq before now) The laptop is a Thinkpad X220 with a hardware switch to turn off and on all radio (wifi, bluetooth, 3G) so I tried that, it had no effect. Then I tried ssh-ing into the machine, and apparantly network-manager was still running and had managed to connect after I switched wifi off and on again. From within ssh everything seemed just fine. I tried killing firefox and restarting lightdm, this had no effect though (how does one restart X in Xubuntu?). I will collect more info if it happens again (saw https://help.ubuntu.com/community/DebuggingSystemCrash after I had rebooted), but for now I've pasted the relevant bits from /var/log/syslog* at http://pastebin.ubuntu.com/1393943/ (all the way down to where I hit the radio switch). Please let me know if there's any more info I can collect, I don't know how to provoke the bug though. $ apt-cache policy xorg xorg: Installert: 1:7.6+12ubuntu1 Kandidat: 1:7.6+12ubuntu1 Versjonstabell: *** 1:7.6+12ubuntu1 0 500 http://no.archive.ubuntu.com/ubuntu/ precise/main amd64 Packages 100 /var/lib/dpkg/status ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: xorg 1:7.6+12ubuntu1 ProcVersionSignature: Ubuntu 3.2.0-33.52-generic 3.2.31 Uname: Linux 3.2.0-33-generic x86_64 ApportVersion: 2.0.1-0ubuntu15 Architecture: amd64 Date: Thu Nov 29 09:26:05 2012 InstallationMedia: Xubuntu 11.10 "Oneiric Ocelot" - Release amd64 (20111012) MarkForUpload: True ProcEnviron: LANGUAGE=nn:en TERM=screen PATH=(custom, user) LANG=nn_NO.UTF-8 SHELL=/bin/bash SourcePackage: xorg UpgradeStatus: Upgraded to precise on 2012-05-11 (201 days ago) ** Affects: xorg (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug precise -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1084434 Title: [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed...
