Jesse, is this a missing feature in KMS? If so, is this on your todo list? No, this should be fixed now, but you may need a new X server. Keith? (In reply to comment #6) > No, this should be fixed now, but you may need a new X server. Keith? You mean newer than xorg-server 1.6.2? I don't know what happened, but it's not working for me either. It worked briefly a few months ago... Ok, the necessary patches didn't get into X server 1.6.2 or xf86-video-intel 2.8.0 I've pushed the (trivial) patch to xf86-video-intel and cherry-picked the patches to server-1.6-branch. I'll do a 1.6.3 release and ask Carl to consider a 2.8.1 release so we can get 'official' versions of the necessary bits released.

Ideally we will be able to take your 1.6.3 release. Best, -Guy |
