dmesg after killing X
7d9a746 - (refs/bisect/bad) sna: Be robust in handling DPMS failures (3 months
ago) <Chris Wilson>
This commit starts causing problems with my laptop's Intel card. If I close an
X session by letting xinitrc finish, then I'm returned to the login screen
without problem. If I kill the X process or stop it via systemctl, then my
laptop display turns off and won't turn back on short of a reboot: starting X
again, and closing the lid, don't help. (I didn't try suspending.)
The laptop's built-in display is seen as eDP1. If there are other displays
attached via HDMI or DP, they continue functioning normally, in console mode
and X. I don't see anything out of the ordinary in the logs.
Machine:
$ uname -a
Linux mikasa 3.18.21 #1-NixOS SMP Thu Jan 1 00:00:01 UTC 1970 x86_64 GNU/Linux
- X Server version 1.17.2
- ASUS N550JK with dual Intel and NVIDIA graphics (only Intel active).
- The xrandr output is from a normally functioning session (from the commit
prior to this bad one).</pre>
