The problem started happening immediately after I upgraded to kubuntu 14.04. (from 13.10)
ck
the monitor is connected to my laptop (DELL XPS 13) via a VGA mini display port.
At boot, it works correctly, but if the screen goes to sleep after some inactivity, then it stays black forever.
(whereas my laptop screen still works), and some error is reported in dmesg.
Notice that I'm talking about screen blacking out after inactivity, *not* a full system suspend: the laptop stays awake.
The bug is similar to https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1314213
If I unplug the VGA adapter, and plug it back, it works again.
