Re: Fixing X220 Video The Right Way

hw.acpi.reset_video used to send this machine X220 into a reboot loop,
with flashing thinklight. Interesting that it no longer causes this
problem. I kind of paused since the trackpad sucks so much in X.

I think since ssh still works, that just the display or graphics port
is off.

It may be worth trying to do some acpi_calls via ssh to try to hack
the display back on...
