Title:
[Dell XPS 13 (L321X)] External monitor does not wake up after sleep
Status in “linux” package in Ubuntu:
Confirmed
Bug description:
The problem started after I upgraded from kubuntu 13.10 to 14.04.
the monitor is connected to my laptop via a VGA mini display port.
At boot, it works correctly, but if the screen goes blank after some
inactivity, then it stays black forever.
WORKAROUND: If I unplug the VGA adapter, and plug it back, it works
again.
