Hi,
this patch breaks X on my box - it is fully responsive and I can log in
into it from another machine but both monitors are black and show this:
"The current input timing is not supported by the monitor display. Please
change your input timing to 1920x1200@60Hz or any other monitor
listed timing as per the monitor specifications."
Reverting it fixes the issue.
Thx.
