Title:
windows stop intermittently responding to mouse control
Status in “lightdm” package in Ubuntu:
Incomplete
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
