Thank you for your answer.

This last line says direct rendering is enable so I assume this is when
you run as root? What does the non-root log say?
The answer for the first question is yes. The Xorg server is started under root account via statement gdm_enable="YES"in /etc/rc.conf. When I disable it and try to run Xorg via startx under non-root account the log output is:

Also, how are you starting X, with startx? If so, is /usr/X11R6/Xorg
setuid root?
/usr/X11R6/bin/Xorg is setuid root.

Do you load the radeon.ko and drm.ko kernel modules from
/boot/loader.conf?
Originally no. I have added it there, but there is no change in behaviour.

Any other ideas?

Many thanks,
Ladislav
