Jerry, I think you may have two different bugs in your logs. Some of them show a backtrace at the end of Xorg.0.log which means that Xorg crashed. Some do not have this and you report that the mouse cursor can be moved but everything else is frozen along with messages in dmesg about the GPU being wedged [1]. For crashes we need a full backtrace, and how to get one is described at [2]. I suggest we focus on the crash and not the GPU hang/freeze here. There is some general information about freeze bugs and especially how to get a batchbuffer dump at [3].
[1]: These messages have been removed from recent kernels as they flood the logs and the message just before that is likely to be more useful: https://bugs.freedesktop.org/show_bug.cgi?id=25477 [2]: https://wiki.ubuntu.com/X/Backtracing [3]: https://wiki.ubuntu.com/X/Troubleshooting/Freeze ** Bug watch added: freedesktop.org Bugzilla #25477 https://bugs.freedesktop.org/show_bug.cgi?id=25477 ** Summary changed: - kernel 2-6-32-9 xorg black screen intel video + [i845g] kernel 2-6-32-9 xorg black screen intel video -- [i845g] kernel 2-6-32-9 xorg black screen intel video https://bugs.launchpad.net/bugs/499102 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
