... you were right. thanks for the hint - is the xgl server wich causes the problemes. after creating the directory "home/user/.config/xserver-xgl" with an empty file named "disabled" in it, the session starts without the xgl-server. now direct rendering works fine. of course there are no desktop effects possible so far. maybe i can fix this with help of the links you sent.
