2 title: Blank DELL on DisplayPort
9 I've been struggling since ever with my DELL U3014 on the DisplayPort
10 saying there's no signal after a power cycle of the monitor.
12 I just found a solution to bring the monitor back to life without rebooting
13 the box; just ssh into and issue:
16 $ DISPLAY=:0 xset dpms force off
17 $ DISPLAY=:0 xset dpms force on
20 I'm running Gnome3 on Arch Linux, so YMMV.
