Arch Linux

I also had problems with this release: I couldn't start X.
The log said: "[dri] RADEONDRIGetVersion failed because of a version mismatch.".
I solved it by installing the Git version.

I also couldn't start X after updating to this version. X starts again after downgrading to previous version.

Can you attach outputs of dmesg and /var/log/Xorg.0.log(.old) that belongs to the failed driver?
Regarding git: the 6.14.4 is current git master, so there should be no differences between the released driver and a git snapshot, unless it's an outdated git snapshot you're using.

Had the same problem, X was falling back to vesa and was plain black.
Removing vesa to force radeon I had an error about RADEON wanting to be used on KMS driver even though my kernel was run with a kms radeon drm.
I downgraded to 6.13-2.

Exact same problem here. Downgrade to 6.14.3-2 solved the problem

Confirming this. I also downgraded to 6.14.3-2.

Same issue here. Unable to startx. Downgrade to xf86-video-ati-6.14.3-2 fixed the issue.

Confirm this. I can't start X with xf86-video-ati-6.14.4-1-i686 installed. Downgrade to xf86-video-ati-6.14.3-2-i686 solved the problem

I can also confirm this, x cannot start with 6.14.4-1 , reverted to 6.14.3-2(64 bit packages).

Same here with similar configuration. Added 'nomodeset' to kernel boot parameter as workaround.

Confirm this. Using fbdev as fallback. And fbdev works fine: correct screen resolution over HDMI output, quite fast and so on... That shows kernel modesetting is operational

Maintainer, JFYI, libdrm must be built _before_ xf86-video-ati.
Simple driver rebuild will solve this problem.

Looks like this driver was compiled without KMS support, so it always starts in UMS mode now. A recompile with latets libdrm should fix that.

I can confirm this bug also. I agree with Jan de Groot: looks like the driver was build with KMS disabled. More details in bug #29178. This seems to be a duplicate of that bug.

After I update xf86-video-ati, I got this in my log file.

Then I install an older version from cache, this problem goes.

I rebuild xf86-video-ati locally via abs and now it works again :)

This is a duplicate of 29178.

On my computer Xorg server will no longer start up. Error says:

Down grading to xf86-video-ati-6.14.3-2-x86_64.pkg.tar.xz fixes problem.

should be fixed in 6.14.4-2

> should be fixed in 6.14.4-2

Yes, thx!
