No xserver with ATI Radeon HD 6800

Hi Everyone!

I just installed arch on a new pc and having trouble getting xserver to run. The main problem is that the kernel states that KMS is activated but xorg doesn't recorgnize it:

those are the only messages relating KMS/drm in dmesg:

[drm] Initialized drm 1.1.0 20060810
[drm] radeon kernel modesetting enabled.

When I try to start X:

grep EE Xorg.0.log
[    60.300] Current Operating System: Linux Bigox 2.6.37-ARCH #1 SMP PREEMPT Fri Mar 25 15:10:00 CET 2011 x86_64
        (WW) warning, (EE) error, (NI) not implemented, (??) unknown.
[    60.483] (II) Loading extension MIT-SCREEN-SAVER
[    60.584] (EE) Failed to load module "vesa" (module does not exist, 0)
[    60.584] (EE) Failed to load module "fbdev" (module does not exist, 0)
[    60.601] (EE) RADEON(0): Chipset: "AMD Radeon HD 6800 Series" (ChipID = 0x6738) requires KMS
[    60.601] (EE) Screen(s) found, but none have a usable configuration.

Honestly I don't what went wrong - so may one of you guys know what to do. If you need more information let me know!

Best,
smax

Re: No xserver with ATI Radeon HD 6800

Just to provide more information:

I did choose the early start method for KMS and did put the radeon module in the mkinitcpio.conf and rebuilt the initramfs. I also added the kernel parameters in grub. But when I start arch linux the screen resolution of the console doesn't change at all.

It goes without saying that without the KMS the xserver wont start either.

Should I try the original ATI/AMD drivers?

Best,
smax

May need to install  xf86-video-ati  . so do a pacman -Ss xf86-video for a list of drivers and type the ati one . by the way i use catalyst with my setup is only a 5770 but works realy good. or just follow

Also do not forget to make sure you have hal installed  and running in daemon from the /etc/rc.conf file.

According to this page (http://xorg.freedesktop.org/wiki/RadeonFeature) the 6800 series wasn't supported with the open source radeon driver until kernel 2.6.38, which is currently still in testing. Until that update goes through, you'll need to use the Catalyst drivers.
