            Bug ID: 421782
           Summary: Dual Monitor support

  Target Milestone: ---

SUMMARY:

Have a strange issue with Plasma not wanting to remember which monitor I set as
the main monitor, the built in monitor of the Lenovo T520 or the Auria monitor
connected to the T520 via DP.

Seems to happen after I sleep the system or do a restart.

One morning is set the Auria monitor to 30Hz refresh rate that at first made me
think my vision or monitor was on its last leg.

Seems to be a very random issue as this morning it came out of sleep just fine
with the monitors settings perfectly intact...

One time it came out off Sleep in the morning but this time it would only let
me choose between 20 or 30 hurts and resolution was maxed at 1920 x 1080 until
after I rebooted the system then it would let me select 60Hz and the true max
res of the monitor of 2560 x 1440

I really have no idea why one day it sleeps and wakes just fine and other days
it just messes up the external monitor?


STEPS TO REPRODUCE
1. Connect second monitor to DP output of T520 Laptop
2. Sleep or restart PC
3. Task bar will move back to laptop display and or resolution and refresh will
be wrong on second display
