In some cases, it works correctly if you first set a low resolution and then gradually step up, but this does not work reliably. I can reproduce this in the current build from http://kernel.ubuntu.com /~kernel-ppa/mainline/drm-intel-next/2012-01-05-precise/ Linux joy 3.2.0-997-generic #201201050433 SMP Thu Jan 5 09:34:48 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux Reply at: https://bugs.launchpad.net/xserver-xorg-video- intel/+bug/745112/comments/118 ------------------------------------------------------------------------ On 2012-01-25T09:13:33+00:00 Martin Pool wrote: I'm very happy to test or debug things here, if someone gives me a pointer where to start.
