Matthew, Can you attach the following files: uname -a > uname-a.log cat /proc/version_signature > version.log sudo lspci -vvnn > lspci-vvnn.log
Also, please attach a complete dmesg log which includes the error point (ie. the point at which your PC display sleeps & then lock-up occurs). Thanks. ** Changed in: ubuntu Status: New => Incomplete ** Summary changed: - When display goes to sleep, it won't wake up again + [Gutsy regression] When display goes to sleep, it won't wake up again -- [Gutsy regression] When display goes to sleep, it won't wake up again https://bugs.launchpad.net/bugs/151513 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
