I'm running Ubuntu 14.04 with xmonad on a relatively new retina MacBook Pro. During normal computing, my screen will turn black every once in a while. Moving the mouse, clicking, or pressing any key turns it back on.
I am running xscreensaver
but there's nothing in the xscreensaver
log file about the blackout event. In Xorg.0.log
, I see:
[ 30821.541] (II) intel(0): switch to mode [email protected] on eDP1 using pipe 0, position (0, 0), rotation normal, reflection none
When I'm watching full-screen media in e.g. VLC, the screen does not do this. I think that running xset -dpms; xset dpms
every minute also prevents the problem.
How do I prevent this from happening in a way that doesn't interfere with normal xscreensaver
behavior?
