[SOLVED] ATI 4850s problem

I am having a problem getting my X working properly on my desktp.

The desktop specs gpu wise are 2 ATI 4850's in crossfire configuration (I'm wondering if that may be the problem) and I am only trying this on one one monitor to limit factors.

I am using the radeon driver (xf86-video-ati), and KDE for the DE. I can get into kde fine, but doing anything graphically, such as moving windows, is very slow and jumpy.

I have tried with and without an xorg.conf (haven't tried enabling KMS yet, not sure if that could help or not), and the results are the same.

when i create the xorg.conf file via

Xorg -configure

the following error gets spit out  (EE) RADEON(1): Cannot read V_BIOS (3) Input/output error. When i actually startx, the xorg log shows:

(EE) RADEON(0) [dri] DRIScreenInit failed. Disabling DRI.
(EE) RADEON(0) Acceleration initialization failed.

This is a new build, but i previously had the same problem on an old build (where the hard drive eventually gave way) with both the radeon and radeonhd drivers using openbox. Any thoughts or advice?

ps here is my Xorg.conf file

That's probably it. I'm not positive but pretty sure crossfire isn't supported by the open source driver, you'll have to use the radeon one.

Re: [SOLVED] ATI 4850s problem

I have taken out the crossfire bridges, and tried again with and without an xorg.conf, and still isn't liking the dri. Anybody have any other advice? I would like to be able to avoid the catalyst drivers if possible, sense they only supporg xorg < 1.65

EDIT: saw in the xorg log (WW) RADEON(o): Direct rendering is not supported when VGA arb is necessary for the device. Did some googling and in theory KMS fixes the DRI issue. Ill give it a shot and post back

Re: [SOLVED] ATI 4850s problem

Any other ideas?

I got KMS working, but now whenever i try to startx it just stays at a black screen. I have tried radeon, radeonhd, and radeonhd-git drivers (with and without xorg.conf) with no luck. I would try radeon-git, but the makepkg fail.

Any other ideas on how i can get my system running short of removing on the cards or buying a new card? Any help at all would be greatly appricated.

Cheers

Re: [SOLVED] ATI 4850s problem

Solved.

I finally got xf86-video-ati-git working (thanks to a new comment in the AUR, perfect timing!! ). That combined with KMS has everything up and running.

Cheers.
