Screen corruption on ATI RV370 with multiple monitors

[Baard Johansen]

Binary package hint: xorg

When attaching a second monitor to my laptop using VGA and launching 'gnome-display-manager' both screens shows a corrupted image. Restarting GDM switches to a mirrored, non-corrupted image. The default resolution on the laptop-screen in 1400x1050 with no xorg.conf

I've also noticed that switching from X to VT1 back to X when adding "Virtual 2424 1050" to xorg.conf freezes the laptop. Not sure if it is related.

Also noticed that resume (after suspend) freezes the computer if I'm using multiple monitors.

I suspect this is a KMS issue.

Just tried http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.33.3-lucid/linux-image-2.6.33-02063303-generic_2.6.33-02063303_i386.deb and everything seems to work!

Hi Baard,

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.
