Summary Sometimes External Monitor stays black after resuming from suspend
Product DRI
Version unspecified
Hardware x86-64 (AMD64)

Sometimes my external monitor (Acer X223W) stays black (powersave mode) when
resuming from suspend. I'm using a HP ProBook 6465b (Llano/Sumo, AMD A6-APU,
Radeon HD6520G). The Monitor is connected to the DVI port of my HP docking
station (P/N: VB044AV).

My Desktop Environment (GNOME 3) still thinks it's connected, so some windows
aren't visible anymore.

Workarounds:
- Press WIN+P to disable the second monitor and use the Laptop screen only
- Power off the external monitor and then switch it on again. It then starts to
work again.
