Bug Description

Binary package hint: xserver-xorg-video-intel

As you can seen on the automatically generated bug report, xrandr lists 3 outputs, one VGA which works perfectly, plus 2 HDMI outputs. This board however only has 2 DVI outputs. One is DVI-I which I use with a VGA adaptor. The other one is a DVI-D which was connected to another monitor with DVI-D input.

Only the analog output of the first DVI-output works, the rest doesn't seem to work. To be fair it might be a problem with my monitor as it neither works on the BIOS setup screens. The monitor is fairly old, but once worked with an old ATI card.

[This is an automatic notification.]

A new major version of the -intel driver is now available in Karmic.

This version includes a major reworking of the acceleration
architecture, which resolves a huge number of issues. We do not know
whether it resolves the issue you reported.

Would you mind testing Karmic Alpha-2 and seeing if it is still a
problem? CD ISO images are available here:


If the issue can still be reproduced on karmic, please report here with
your findings, and attach a fresh Xorg.0.log from your test, and we will
be able to forward the bug upstream.

Otherwise, if the bug no longer exists in Karmic, let us know that as

In the off chance you encounter different bugs while attempting to test
Karmic, please report those as new bug reports.

Marking this as a duplicate of bug 384660 as it seems they will be resolved by the same kernel patch. Please continue to track this issue at that report. Thanks.

I think the duplicate status is wrong. The fix doesn't fix my problem, it only changes it. Now xrandr reports:
