I am currently testing GNOME 3.8 and often the UI freezes. This does not seem to be related to some special actions by the user because it happens sometimes when I am working at the computer but also sometimes after idle when I come back to keyboard. Also, sometimes I am able to change to the text console and restart gdm but sometimes i can only cold reboot the machine. I am not sure whether this is a bug in gnome, mutter, xorg or something else so I am using GNOME as component first, because it does not happen with Xfce for example. I looked in to the logs (syslog, dmesg, xorg, gdm log) but could not find anything helpful. Please give me a hint on how to debug this. Please let me know if you need more information.

I think it's: https://bugzilla.gnome.org/show_bug.cgi?id=704646 that should be solved as soon as any of us is able to apply that reversion patch from gnome-3.8 branch that is causing lots of problems

I agree that the upstream issue could be my problem. I will try the patch later to see if it solves my problems. Is there a problem in applying the patch or did nobody from Gentoo try it?
Feel free to go ahead and apply it (you will need to restart gnome-shell after that, probably gdm too)
(In reply to Pacho Ramos from comment #3) > Feel free to go ahead and apply it (you will need to restart gnome-shell > after that, probably gdm too) Done. Applied the patch as follows: 1.) Download https://bugzilla.gnome.org/attachment.cgi?id=251832 2.) Copy it to /etc/portage/patches/gnome-base/gnome-shell-3.8.4/Revert-background-fix-asynchronous-management-of-b.patch 3.) emerge -1 gnome-shell 3.) Restart gnome-shell I will now test it for 2 days and see if any freeze occurs.
please ensure you see the patch being applied at prepare phase when "emerge -1 gnome-shell"
(In reply to Pacho Ramos from comment #5) > please ensure you see the patch being applied at prepare phase when "emerge > -1 gnome-shell" Yes, it has been applied.
I'm definitely having a similar issue which forces me to SIGKILL gnome-shell every now and then. I'll try the patch, time permitting.
So.. my observation after 2 days of heavy use with the gnome-shell patch applied is as follows: The number of freezes was drastically reduced to 1. This freeze was after waking up from suspend and I could only perform a cold reboot to regain access. My assumption is that this is a bug in xorg (I recently upgraded my system to xorg-server-1.14.2 to see if it fixed gnome-shell freezes, stable list #475480). I will downgrade to stable xorg and see if all lockups are gone afterwards.
Usually bumping mesa helps (or changes things)... but it's a separate problem (the problem with gnome-shell crashers/hangs is that they can be caused by many different things :S)
So far, no freezes after an evening of heavy use. Looks promising.
(In reply to Pacho Ramos from comment #9) > Usually bumping mesa helps (or changes things)... but it's a separate > problem (the problem with gnome-shell crashers/hangs is that they can be > caused by many different things :S) Yeah. What I wanted to say was: The patch fixes the bug in gnome-shell but I have another bug in xorg or something on my system.

Oops, I forgot you thank you on ChangeLog :@ Sorry a lot. Anyway, thanks for reporting and testing :)
