With lockup bugs, usually what's happening is the GPU has hung due to some bad register setting.
There is a tool for taking a snapshot of the GPU's register settings, `intel_reg_dumper`, which is available as part of the xserver-xorg- video-intel-dbg package. So install that, and then run this tool in two cases: 1. With the display working properly sudo intel_reg_dumper > reg_good.txt 2. After reproducing the lockup (you'll need to ssh into the box from a 2nd machine): sudo intel_reg_dumper > reg_bad.txt Then attach both files to this bug report. We can send the report upstream for there to see if a fix can be identified. -- [i945GM] Display locks-up in various circumstances https://bugs.launchpad.net/bugs/353898 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
