[g45] DVI not detected
Last modified: 2009-07-29 19:03:17 UTC
Forwarding this bug from Ubuntu reporter w074n:
Driver detects all outputs as disabled when VGA port being used. Works okay with vesa.
I've got a Intel G45 chipset with a X4500HD. It was installed with the vesa driver as already the desktop install cd failed to use the intel driver.
So I tried to use the intel driver manually, which always resulted in the X server not starting up giving this error message: "(EE) intel(0): No valid modes.". Because of that i thought it might be related with bug #194760. Therefore I added the information about the modes to xorg.conf and still it gave the same error.
Then I connected the display via VGA, not DVI and everything is working just fine.
$lspci -nn | grep VGA
