I have compiled xf86-video-intel with --enable-debug=full but it makes crash
kde-plasma desktop. 
I'm trying to start app with other window managers or without any (xinit +
shell script with xrandr) but in both cases I only get visual artifacts, (giant
fragments of gears).
There has to be something missing in X startup sequence/permissions.

Thanks.
