[Bug 1501941] Re: Screen turned off after X server exits
I've uploaded this change to wily. There is a possibility that there might be a regression for some users with DPMS but I think that is less severe than the effect on those who are left with the screen off.

[Bug 1501941] [NEW] Screen turned off after X server exits
Public bug reported: When the X server exits, the screen turns off and doesn't seem to re- enable. The system is still running (i.e. can SSH in). To reproduce: 1. Log into a session 2. Switch to the greeter (using indicators or running "dm-tool switch-to-greeter" from a terminal") 3. Log back into session Expected result: You return to the session Observed result: Screen goes black This appears to be an issue in the Intel drivers, it occurs with the current wily (2:2.99.917+git20150808-0ubuntu2). It does not occur when downgrading to the vivid version (2:2.99.917-1~exp1ubuntu2.2 with some patches to compile in wily). ** Affects: xserver-xorg-video-intel (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1501941 Title: Screen turned off after X server exits To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1501941/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I've put a patched version of the Intel driver in ppa:robert-ancell/xorg [1].
