Created attachment 30985 [details] dmesg log I did a bisect and found that the commit 8a9832e89ff1bc7a039c8f966f07101570be3d5e (disable D1VGA and D2VGA if enabled) has caused a regression for me. That commit caused my secondary display to not display anything with KMS enabled, but the primary display works fine. Xorg seemed to think that the display is there though, since I can move windows off screen; I just can't see them. Attaching dmesg log. Thanks.
Looks like I forgot to mention that this commit is in airlied's drm-next kernel branch.
Wierd, can you retry with latest drm-next?
Pulled drm-next, and the problem is still there. I looked a little more closely at the commit, and I found it's in rv515.c, but I have an rv770. So I don't know why it affected me at all. Maybe I'm just a really bad bisecter; I'll try again and see if I get the same result.
Yep, I got the same result. Additionally from the current HEAD I reverted 8a9832 and it's working fine. So maybe the real question is why a file for rv515 affecting my rv770?

hmm .. have the same problem and i've bisected it to the same commit. radeon 4800 (r700 i think) here. should have looked into bugzilla first :)
i'm sorry to bug you, but as i read the pull request i wonder what's the plan with this known regression.
Fixed for me by 8ccb5075a99434f88b4445723970f1402e13c26c It's currently in the drm-radeon-testing branch. @Florian - This commit is not in the drm-linus branch, so Linus won't be pulling this commit this time. I'm going to close this bug because it works for me, and it apparently works for Dave since he committed it after all.
hmm .. according to http://git.kernel.org/?p=linux/kernel/git/airlied/drm-2.6.git;a=shortlog;h=refs/heads/drm-linus it is in drm-linus. will test the fix soon ..
