I add a similar problem too.
Using sddm with xfce4.
Login agent 'sddm' with same symptoms as yours.
I fixed it by :
A downgraded xf86-video-ati to previous version,
Adjusted screen set-up to xorg default ( change from 1600x1200 @75hz to 60hz
which is the default set-up for all distro on that machine)
Removed all config in radeon at /etc/X11/xorg.conf.d/10-radeon.conf
Reboot @ upgrade xf86-video-ati to 7.10
Upgraded successfully !
Customized radeon with previous set-up
Hope this work for you if you try !</pre>
