Indeed!:

root at blackrider:~# lsof /dev/dri/card0 
COMMAND    PID USER   FD   TYPE DEVICE SIZE NODE NAME
dbus-daem 2195 rene    4u   CHR  226,0      6988 /dev/dri/card0

How the heck does this gonna happen?!?!? Killing it away gives me
DRI and thus a pretty 3D desktop back.

If the error message would not have been -EPERM but -EBUSY (or so) I
would have noticed weeks ago, but with -EPERM I basically thought "what
the heck" is going on in the kernel, ...

Anyone any idea why this dbus-daemon open the device?

Yours,
