I'm experiencing the same issue as mentioned as in several comments, specifically #13, #14, #39, that is using gnome-shell on 11.10; I especially get a freeze of the shell when scrolling (w/ mouse wheel or by pressing middle button and dragging the document) through a PDF in evince, but I also got it once in firefox. I can go to a VT and usually I restart the lightdm service to get back to my desktop. I am now on the v3.3-rc6-precise kernel and I could still reproduce the freeze by grabbing a PDF document in evince with the middle mouse button and then shifting it around like a maniac. Some other remarks: . My laptop has an ATI Mobility Radeon X2300 (ATI was also mentioned earlier in this report so I wonder why only intel drivers have been tagged here). . I really don't see how this is a duplicate of #808384, it seems like a completely different issue, except that there's an error message in kern.log: [drm:drm_mode_getfb] *ERROR* invalid framebuffer id. This error sometimes, not always, occurs in kern.log right after a freeze. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/783993 Title: unity freezing periodicly [drm:drm_mode_getfb] *ERROR* invalid framebuffer id To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/783993/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
