I'm trying to get as deep as I can in gdb, but I don't have much time to play with this, so if someone is interested may be I can get some help ;) (or may be it's not useful, just let me know). gdb output attached. I'm using xserver-xorg-video-intel_2.1.1~git20071004-0ubuntu1_i386.deb, so no compiz.
Steps I did to get this gdb output: 1. Clean boot, no compiz. 2. Try to set normal visual effects in gnome-appearance-properties, but it's not possible. 3. Switch to VT1, switch back to VT7. 4. Attach X to gdb through ssh. 5. Play ~/Examples/Experience\ ubuntu.ogg (totem + xv). 6. Switch to VT1 while video is playing. 7. In gdb, when SIGUSR1 is detected, get a backtrace full, then try to finish all frames. After the last finish command, you can see the gray blocks, and networking hangs. May be we can get deeper if we do steps instead of the last finish. ** Attachment added: "gdb-X.txt" http://launchpadlibrarian.net/9846058/gdb-X.txt -- laptop hangs when switching video mode https://bugs.launchpad.net/bugs/127101 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
