Bug Description

Binary package hint: xserver-xorg-video-intel

This was working well based on Beta with the maximum resolution of the monitor being supported.

 I did an update last night and since then I am unable to use a higher resolution than 1024 x 768. The screen also shows as 'unknown' make in the graphical chooser.

Afaik we did not post any X.org updates yesterday (we're frozen for beta). Perhaps there was a kernel change causing this.

Can you please attach your /var/log/dpkg.log ?

Also, try booting an earlier kernel (hold down the left shift key during boot to get into grub, then select an earlier kernel version).

Okay, well my assumption is this is a kernel drm bug, since with KMS it now is responsible for setting up outputs and selecting appropriate resolutions for the given monitor. My guess is that a kernel update may have introduced a regression or something.

Hi Chris,

If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.
