I'm currently stuck in the state described. I can quit/close whatever window is on top, and it'll take me to the next window. That's how I got to this browser window. The keyboard focus works, but the mouse clicking doesn't do anything, even tho the mouse pointer works fine. I had to tab thru all the links on this page to get to this text field in order to type and paste stuff into it.
I found a clue, when this bug hit, I had emacs on top that I had launched from Terminal. Clicking in the emacs window didn't cause any messages to be sent to the Terminal, but clicking anywhere outside of the topmost emacs window caused these messages to print in the Terminal (emacs:11780): Gdk-CRITICAL **: IA__gdk_window_get_events: assertion `GDK_IS_WINDOW (window)' failed (emacs:11780): GLib-GObject-CRITICAL **: g_object_ref: assertion `G_IS_OBJECT (object)' failed (emacs:11780): GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)' failed (emacs:11780): Gdk-CRITICAL **: IA__gdk_window_get_events: assertion `GDK_IS_WINDOW (window)' failed (emacs:11780): GLib-GObject-CRITICAL **: g_object_ref: assertion `G_IS_OBJECT (object)' failed (emacs:11780): GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)' failed (emacs:11780): Gdk-CRITICAL **: IA__gdk_window_get_events: assertion `GDK_IS_WINDOW (window)' failed (emacs:11780): GLib-GObject-CRITICAL **: g_object_ref: assertion `G_IS_OBJECT (object)' failed (emacs:11780): GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)' failed (emacs:11780): Gdk-CRITICAL **: IA__gdk_window_get_events: assertion `GDK_IS_WINDOW (window)' failed (emacs:11780): GLib-GObject-CRITICAL **: g_object_ref: assertion `G_IS_OBJECT (object)' failed (emacs:11780): GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)' failed (emacs:11780): Gdk-CRITICAL **: IA__gdk_window_get_events: assertion `GDK_IS_WINDOW (window)' failed (emacs:11780): GLib-GObject-CRITICAL **: g_object_ref: assertion `G_IS_OBJECT (object)' failed (emacs:11780): GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)' failed (emacs:11780): Gdk-CRITICAL **: IA__gdk_window_get_events: assertion `GDK_IS_WINDOW (window)' failed (emacs:11780): GLib-GObject-CRITICAL **: g_object_ref: assertion `G_IS_OBJECT (object)' failed (emacs:11780): GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)' failed (emacs:11780): Gdk-CRITICAL **: IA__gdk_window_get_events: assertion `GDK_IS_WINDOW (window)' failed (emacs:11780): GLib-GObject-CRITICAL **: g_object_ref: assertion `G_IS_OBJECT (object)' failed (emacs:11780): GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)' failed (emacs:11780): Gdk-CRITICAL **: IA__gdk_window_get_events: assertion `GDK_IS_WINDOW (window)' failed (emacs:11780): GLib-GObject-CRITICAL **: g_object_ref: assertion `G_IS_OBJECT (object)' failed (emacs:11780): GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)' failed (emacs:11780): Gdk-CRITICAL **: IA__gdk_window_get_events: assertion `GDK_IS_WINDOW (window)' failed (emacs:11780): GLib-GObject-CRITICAL **: g_object_ref: assertion `G_IS_OBJECT (object)' failed (emacs:11780): GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)' failed (emacs:11780): Gdk-CRITICAL **: IA__gdk_window_get_events: assertion `GDK_IS_WINDOW (window)' failed (emacs:11780): GLib-GObject-CRITICAL **: g_object_ref: assertion `G_IS_OBJECT (object)' failed (emacs:11780): GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)' failed (emacs:11780): Gdk-CRITICAL **: IA__gdk_window_get_events: assertion `GDK_IS_WINDOW (window)' failed (emacs:11780): GLib-GObject-CRITICAL **: g_object_ref: assertion `G_IS_OBJECT (object)' failed (emacs:11780): GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)' failed (emacs:11780): Gdk-CRITICAL **: IA__gdk_window_get_events: assertion `GDK_IS_WINDOW (window)' failed (emacs:11780): GLib-GObject-CRITICAL **: g_object_ref: assertion `G_IS_OBJECT (object)' failed (emacs:11780): GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)' failed -- 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. 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) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/925743/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
