   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:
  14
  15 ```shell
  16 $ DISPLAY=:0 xset dpms force off
  17 $ DISPLAY=:0 xset dpms force on
  18 ```

  20 I'm running Gnome3 on Arch Linux, so YMMV.
