[Solved] Artifacts with ATI Radeon HD 6670 and open source driver

Hey folks,

I use the xf86-video-ati driver and have a lot of artifacts on my screen.

Here my Xorg and dmesg log:

Dmesg: http://pastebin.com/AF8AmJfP
Xorg: http://pastebin.com/8rnQS0sa

My kernel version: 3.8.8-2-ARCH

My /etc/X11/xorg.conf.d/20-radeon.conf:

Section "Device"
    Identifier "Radeon"
    Driver "radeon"
    Option "EXAPixmaps" "off"
    Option "AccelDFS" "off"
EndSection

I tried to use the linux-lts kernel and the mesa-git repository but nothing happend...

KMS is enabled, if I disable it Xorg only works with vesa but very slow and with a bad resolution.

All other framebuffers devices are disabled.

I hope someone can help me...

[    36.785] (WW) RADEON(0): Option "AccelDFS" is not used

have you tried with EXAPixmaps and AccelDFS lines commented out ?

Yes I have...no changes...

I could use the ati catalyst driver to solve this problem but I hate this slow driver.

EDIT:

I also have artifacts on my virtual console...

Change /sys/class/drm/card0/device/power_profile from default to high fix my problems...

Re: [Solved] Artifacts with ATI Radeon HD 6670 and open source driver

then your card is probably initialised in low power mode by bios / (U)Efi , and thus uses lower clocks.
In that mode, it's doesn't seem to have enough power to drive your system without artifacts.

I have artifacts with Dynamic frequency switching and Profile-based frequency switching in default mode.

I have no problems with the power profiles low, mid and high.
