I have also entered a bug in the bugzilla at freedesktop.org. This bug is number 58594. I was advised in response to that bug that many changes have been made in related software recently and I should try a "drm- intel" daily build of kernel 3.7.0 plus the entire suite of "xorg- edgers" updates.
I was able to do this; more details are available at the freedesktop bug. But there was no change in behavior. I think it is noteworthy that both my computer and mikesmithv's computer use the same i954 chips even though they are otherwise different. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1079440 Title: Random complete freeze using dual monitors To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/1079440/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
