I just installed Ubuntu 12.10. For some reason I can not get the DVI to work. The monitor says: Cable not connected. The VGA cable works, but the everything looks blurry. The resolution is fine 1920 x 1200 and it even knows that I have BenQ 24".
I have 2 video cards.
- AH3450/HTP/256M (ATI Radeon HD 3450) AGP (ports: VGA:ok DVI:not working).
- EN7600GT/2DHT/256M (nVidia®’s GeForce 7600GT) PCI-Express (ports: DVI:not working DVI:not working)
What should I do to get my DVI:s to work?
