Can't get Intel GMA 950 (KPC K48) to work on DVI

[mixersoft]

I have mythbuntu 8.04.1 installed on my KPC K48. Works fine on the analog/VGA connection, but not on the DVI connection.

On power-up using DVI, I can see the GRUB loader and Mythbuntu splash screen, then it blacks out. It sounds like a driver is being loaded up wrong somewhere, but I'm not sure how/where to look.

TIA.

I'm having a very similar problem with the same graphics card. My S-video out works fine but my DVI doesnt. Unfortunately, I dont have a VGA out.
