GNOME Bugzilla – Bug 92102
Intermittent Desktop Hang
Last modified: 2009-08-15 18:40:50 UTC
Package: metacity Product: metacity Synopsis: Intermittent Desktop Hang Severity: critical Priority: Immeadiate Bugzilla-Product: metacity BugBuddy-GnomeVersion: 2.0 Sun Gnome2.0 Beta2 Build_5 This is an intermittent Desktop hang that renders the Desktop unusable. A number of people have come across this, commencing from build_4. Basically at random points the Desktop focus stay with a given application, all mouse clicks fail. Actions with the focus applications are still sometimes possible. The last time I had this problem, gnome-terminal had focus. However, I could use the "Open" Sun keyboard key to minimise gnome-terminal - but due to a bug this actually causes a "Shade" activity to take place. When I did this the Desktop was usable again. A subsequent "Unshade" rendered it virtually unusuable again. brett.muir@sun.com 2002-08-29 I've run into this problem about every other day since installing Beta2_04. However, I've not been able to track down exactly what is causing the problem - I can't spend much time because its on my desktop and I need to get the system back. (To recover, I log into the system from another machine and kill 'gnome-session' which will exit the hung desktop and put it back at the login screen.) Brett Muir brett.muir@sun.com 2002-08-29 It may not help much, but ... It just happened to me again after I opened a terminal window (one of many). Since I had focus in that terminal when the desktop hung, I was able to continue working in it. Rather than blowing away everything via killing 'gnome-session' as mentioned above, I just killed 'gnome-terminal'. Granted all my terminals ceased to exist, but my desktop unfroze and all other apps appeared to be ok.

Some more commentary I've come across this a couple of times since installimg Sun Gnome2.0 Beta2 build4 yesterday. I found that a double click on another window sorted it out for me. I'll see if I can narrow down the cause of it and let you know. The few times it happened I was using netscape 7 from /usr/dist/share/netscape,v7.0/beta/
Adding gnome-bugs@wipro.com and gnome_bugs@sun.com in the CC list.
This paricular problem seems to relate to metacity fucusing problem. I have logout and login and one of the program crashed, then it hanged at gnome_segv dialog. I had also seen this happened when I started up apps from the applications menu and fairly quickly click on something else. The one workaround is that one can use Alt-Tab to get a terminal window into focus and then pkill the application that hanged. You should then get back to normal.
The thing to do is probably to run metacity with env variables METACITY_VERBOSE=1 METACITY_USE_LOGFILE=1 and after the hang, attach the last chunks of the log file. Those should record what happened or at least give some clues.
Karl, Prabhut, was this verified as being a sun-patch specific problem?
This looks like sun-patches specific problem. By backing out a patch against src/display.c change which was given by metacity/318-83357-w.diff, one of the grab problems I constantly experienced with Netscape7 stops happening. Bug 83557 is "Modal Dialog behaviour is broken". which sounds really likely.
oops, it's Bug 83357. putting this in dependencies.
sorry to have not updated on this bug a little earlier, it seemed to have caused by a specific patch in sun patches directory which was not initializing a variable and hence the intermittent hang. this has been fixed and the new patch uploaded to sun patches directory. Its been caused by a patch which is not as such visible in the community. Jeyasudha can you please update this bug.
Sorry the problem is due to modal dialog patch and i recreated the patch and uploaded in sun-patches. I have added the new patch in Bug 83357 also. Please check the same.
Closing.
