Re: Can not start X : Input/output error on /dev/nvidia0
I am having the exact same issue with a Panasonic PT-AX200E projector + XFX nForce-630i+GF7150 mobo.
I have not yet attempted a driver / bios update, but I get the exact same symptom. Found your thread googling on "NVRM: RmInitAdapter failed! (0x31:0xffffffff:1004)".
VGA works great though. but not DVI-D nor HDMI.
Keep me posted!
