Description Bryce Harrington 2009-07-27 19:59:31 UTC
Forwarding this bug from Ubuntu reporter w074n:

Driver detects all outputs as disabled when VGA port being used.  Works okay with vesa.

[Original Description]
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
