Hypothesis is, that using xrandr on the command line is more robust than
using gnome-display-properties:

Series of 10 tests,
this sequence repeated 5 times per test:
xrandr -s 1024x768 --rate 60
xrandr -s 1920x1200

Results:
working: x x x xxxx
broken :  X X X
          broke during 3rd attempt when going to 1024x768, flickering screen
            broke during 2nd attempt when going to 1024x768, flickering screen
              broke during 5th attempt when going to 1920x1200, display slept

Observation: after resolution change to 1920x1200 pixel errors where observed 
on the lower right screen, looking like a gradient developing from lower right
to center of screen. This happened some, but not all times.

Series of 5 tests,
using gnome-display-properties

Results:
working:
broken:  XXXXX
         broke during 1st attempt when going to 1024x768, flickering screen
          same as 1st test
           same as 1st test
            same as 1st test
             same as 1st test
