Quick check yesterday: X keeps running, but the screen switchs to black.
(the same black as if starting without VGA cable connected.)
Switching back to 59.9 was not possible for me, but i had only 5 minutes to
try this. What is the Correct command for this. (run on ttyN)

I _think_ i have seen the monitor running a useable X with 60, but im
really not shure about this, i've seen too many different outputs of
xrandr during my tests before writing this bugreport.
