This MB has three video outputs (RGB, DVI and HDMI). Ubuntu detects both the RGB and DVI monitors properly, but doesn't show anything on the DVI. I can tell it is trying to display something, because the DVI monitor displays a "no signal" message when the system is in power-save mode and immediately goes black when I move the mouse.
My processor is a i3 540.
I have the BIOS set to IDG+PCE. I tried all the other options too (PCI wasn't a good idea, since I don't have a graphics card, but I tried it anyway).
So, what is it that I am missing?
