Now I have the problem them (not 100% reproducable but happens quite often) that I have no accelerated GL in X11 after boot. This is quite bad even in desktop mode because I get tearing with the kwin compositer in Xrender mode.
The interesting part from the log (attached):
[     9.295] (II) xfree86: Adding drm device (/dev/dri/card0)[     9.295] (EE) /dev/dri/card0: failed to set DRM interface version 1.4: Permission denied
This doesn't happen when I logout again, press Alt+e (to restart the Xserver) and test again. But of course my compositer settings are all bogus again and I have manually change back to OpenGL compositing each time this happened.
