For HDMI radomly flicker issue, I can duplicate it and I debug it for 2 days,
no result. Or more accurately, this issue only occur on DVI->HDMI card, if I
attach the monitor to HDMI on board directly, 1920x1200 works well, no flicker.

To be more precise, if monitor is connected to DVI->HDMI card, even 1280x1024,
monitor will flicker also on a low repetition rate.

So I think maybe it's related to DVI->HDMI card, anyway, in Windows it works
well.
