DVI output on Ubuntu fails

Mononofu · 02-23-10, 02:33 PM

Two days ago, my monitor just stayed black when I booted up my laptop. Additionally, it's also black in the BIOS, so basically the whole time. I then tried Win 7 and Mac OS X, and both worked fine (read: when the OS was loaded, my monitor turned on and worked normally)

VGA still works normally (my laptop has only a DVI-I port for which I have a VGA adapter), but just looks ugly at 1920x1200.

I don't have any idea why the behavior of my laptop changed - before, DVI worked the whole time. There are no BIOS options relating to graphics, so I can't do anything there.

Do you have any ideas what I could do about that?

If not even BIOS is showing on DVI then it obviously can't be Ubuntu or any OS or any driver or configuration. It seems to me that's a hardware issue. DVI cable broken or the DVI jack on screen or on videocard side has a broken pin or such.

Again, DVI works fine on Windows 7 and Mac OS X, therefore it can't be a hardware defect. It's only not working on Ubuntu and in the BIOS.
