Re: After Yum update X no longer works
I see your problem. The EDID in your display is badly broken:
(--) NVIDIA(0): Valid HSync Range : 1442kHz - 80kHz
(--) NVIDIA(0): Valid VRefresh Range : 640Hz - 120Hz
and as a result, you're getting:
Mode pool is empty
What kind of a display are you using?
You should be able to work around this by adding the IgnoreEDID X option.
