So the latest patch doesn't help for the VGA monitor not going off? Please attach the output of xrandr --verbose when both monitors are enabled. It doesn't matter whether or not any of my patches are enabled when you do that.
The kernel panic is a kernel bug and probably not directly related to my patches or your issues. It may indicate that Xorg crashed though; was there anything interesting in Xorg.0.log.old after it happened? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1577170 Title: screen cannot be turned back on after being switched off after some time of inactivity To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/1577170/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
