Hi, I got the same problem. I have an ati HD5770 and tried with xorg 1.8, kernel 2.6.34, xf86-video-ati (don't know which version it was...) and catalyst 10.7 . But since it works for me without kms i didn't care much about it... 2010/8/29 Waylls <waylls@lavabit.com>

So, such a problem.

With 2.6.35(and, it starts from 2.6.34.3) with enabled KMS(ati videocard, HD4570) i can't run X with both xorg 1.8 and xorg 1.9. Now, i have mesa,libgl,ati-dri,xorg-* packages, xf86-video-ati from testing, 2.6.35.4 from here to and still nothing. With enabled KMS screen just freezes at startx(i'm using ion3, no DE) and that's it. No messages in log. No troubles in dmesg too, KMS starts normaly.

Software versions:

kernel: 2.6.35.4 (testing) X: xorg 1.9(testing) drivers: xf86-video-ati 6.13.1-2 (testing) libgl: 7.8.2-3 (testing) mesa: 7.8.2-3 (testing)
