DRI extension is not enabled when the server is configured to use 'EXA" acceleration method. The system becomes flaky and most of the applications work slowly (especially OpenOffice). Reproducible: Always Actual Results: DRI is not used the system works slowly under X
Did turning off kernel mode-setting, as recommended in http://bugs.archlinux.org/task/16691, end up solving this problem?
@Tomáš, what say you? :)
We would need some additional informations, like xorg-server version.
At least Xorg.0.log would be necessary to determine the cause

Sorry for the delayed answer...
And there is a warning that "(WW) RADEON(0): Direct rendering disabled".
Your actual problem is this: drmOpenDevice: node name is /dev/dri/card0 [drm] failed to load kernel module "radeon" (EE) RADEON(0): [dri] RADEONDRIGetVersion failed to open the DRM [dri] Disabling DRI. Probably your kernel is missing DRM_RADEON support.
Sorry, my bug report is absolutely wrong. The kernel compilation was broken in some way and the radeon DRM had not been compiled correctly.
Thank you, Chí-Thanh! (:
