[SOLVED] xf86-video-ati 7.0.0: X doesn't start any more

I enabled KMS for my system quite a while ago, and it worked without problems. After a long pause, I did a full system update today, and Xorg is telling me this: http://sprunge.us/FIYA

(As an observation, KMS doesn't seem to be active since the resolution doesn't change during booting, which it used to do.)

I have a Radeon HD 6770.

Downgrading to 6.14 didn't help at all: KMS was apparently disabled, KDE started, but with both displays in clone mode (which couldn't be changed), and X crashed when changing to tty and back to X.

There are a couple of threads reporting problems with the update, but I don't get a segfault, just the error message "no screens found".

Fix KMS. UMS isn't supported anymore.

KMS early start is enabled. I followed the instructions in https://wiki.archlinux.org/index.php/Ra … _KMS_start.

linux video depends on more things then the xf86-video-* drivers.
Others with similar problems found that using the 3.7.1-2 kernel from [testing] repo solved problems on similar radeon cards as yours.

Try switching to that kernel.


Booting with apg Openrc, NOT systemd.
Automounting : not needed, i prefer pmount
Aur helpers : makepkg + my own local repo === rarely need them

I tried to wait until 3.7 hit 'core', but now I tried using it from 'testing'. I upgraded 'linux' and 'linux-headers' and the error persists.

Turns out it was indeed my fault. I had a file in modprobe.d which disabled KMS, but I don't know how it got there (it was there for quite a while – maybe I just didn't notice it). Removing it solved the problem.
