Public bug reported:
I inquired about this on #ubuntu, so I'll just copy the log here: (04:02:57 PM) _hc: hey all, I'm a long time Debian (since '98) and Ubuntu (since '06) user and I'm having a maddening issue with my Oneiric setup. Basically, every 30-300 minutes, something freaks out and I cannot move or select windows with my mouse, I can sometimes alt-tab between windows when this happens but not always. Sometimes it goes away, mostly I have to reboot to fix it. This happens in GNOME Classic/gnome-wm, GNOME Classic/compiz, Unity 2D, and GNOME sessions. I can't figure it out, its driving me crazy (04:06:22 PM) rigved: _hc: i think that there nothing common between all those sessions, other than X itself. (04:06:32 PM) _hc: rigved: compiz? (04:06:54 PM) _hc: rigved: no, I guess not, since I used gnome-wm... that's why its driving me so crazy (04:08:27 PM) rigved: _hc: you mean that you are using gdm and not lightdm? (04:08:49 PM) _hc: rigved: I'm using lightdm (04:08:49 PM) rigved: _hc: i thought that Unity 2D does not use compiz... (04:09:17 PM) _hc: rigved: right, nevermind, in my original GNOME Classic session, I was using gnome-wm with no compiz (04:09:56 PM) _hc: rigved: then I changed it to use compiz, and the bug is still there, but a little different: basically I can't alt-tab thru the windows after it freaks out with GNOME-Classic/compiz (04:10:37 PM) rigved: _hc: when you say freak out, you mean that mouse is disabled, right? (04:10:47 PM) _hc: nope mouse works fine (04:10:59 PM) _hc: its just clicking on things mostly doesn't work (04:11:53 PM) _hc: rigved: everything continues to run and work fine, I just can't use the mouse to move windows, select windows, or click things in windows that do not have focus (04:12:28 PM) rigved: _hc: ok. (04:12:29 PM) _hc: often, if a window has focus after the freakout, I can still close it with the mouse (04:13:12 PM) rigved: _hc: and is this machine a laptop? (04:13:23 PM) rigved: _hc: ok. (04:13:26 PM) _hc: yes, Macbook Pro 3rd gen (04:13:42 PM) _hc: I was running maverick on it very nicely, then upgraded to natty then oneiric in a day (04:13:45 PM) _hc: then this started happening (04:15:10 PM) rigved: _hc: this looks like a bug. maybe it has got something to do with the upgrade. maverick to oneiric is a gnome 2 to gnome 3 upgrade. (04:15:42 PM) _hc: rigved: yeah, seems likely. I didn't have natty on long enough to know if this happened there (04:16:51 PM) rigved: _hc: i think you should file a bug report against lightdm, cause that seems common to all. (04:17:29 PM) _hc: rigved: Ok, will do (04:17:38 PM) _hc: rigved: any troubleshotting ideas? (04:18:21 PM) rigved: _hc: i can only think of looking through the logs to find any culprit application (04:18:59 PM) _hc: rigved: I've tried running without certain applications, at this point it would have to be gnome-terminal or firefox, since those are the only two that I really always run hans@palatschinken ~ $ lsb_release -rd Description: Ubuntu 11.10 Release: 11.10 hans@palatschinken ~ $ apt-cache policy lightdm lightdm: Installed: 1.0.6-0ubuntu1.2 Candidate: 1.0.6-0ubuntu1.2 Version table: *** 1.0.6-0ubuntu1.2 0 500 http://mirror.anl.gov/pub/ubuntu/ oneiric-updates/main i386 Packages 100 /var/lib/dpkg/status 1.0.6-0ubuntu1.1 0 500 http://security.ubuntu.com/ubuntu/ oneiric-security/main i386 Packages 1.0.1-0ubuntu6 0 500 http://mirror.anl.gov/pub/ubuntu/ oneiric/main i386 Packages ProblemType: Bug DistroRelease: Ubuntu 11.10 Package: lightdm 1.0.6-0ubuntu1.2 ProcVersionSignature: Ubuntu 3.0.0-15.26-generic-pae 3.0.13 Uname: Linux 3.0.0-15-generic-pae i686 ApportVersion: 1.23-0ubuntu4 Architecture: i386 Date: Thu Feb 2 16:24:56 2012 ProcEnviron: SHELL=/bin/bash PATH=(custom, no user) LANG=en_US.UTF-8 SourcePackage: lightdm UpgradeStatus: Upgraded to oneiric on 2011-10-19 (105 days ago) ** Affects: lightdm (Ubuntu) Importance: Undecided Status: New ** Tags: apport-bug i386 oneiric -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/925743 Title: windows stop intermittently responding to mouse control Status in “lightdm” package in Ubuntu: New Bug description: I inquired about this on #ubuntu, so I'll just copy the log here: (04:02:57 PM) _hc: hey all, I'm a long time Debian (since '98) and Ubuntu (since '06) user and I'm having a maddening issue with my Oneiric setup.
