Same problem with this patch. Well in fact, it's even worse as I got a kernel panic when trying to switch from 2 screens to only one (see picture attached).
I attached the output of xrandr before and after the black screen (but before the complete crash). The black screen when changing between one and two monitors also appears without the patch. -- 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
