advises follow:
- entirely remove the dri-section
- try adding a
SubSection \"extmod\"
Option \"omit xfree86-dga\" # don\'t initialise the DGA extension
EndSubSection
to the modules-section. if the problems extend with this, omit it

- add a bit more config to your device-section, perhaps also modify some environment-variables. see /usr/share/doc/nvidia-glx/README.txt.gz for further information
- run a system-update, because x.org just entered testing, i think. if you use x.org, the config-file has to be /etc/X11/xorg.conf
- try to use the latest drivers from the sources i posted above. it\'s the personal repository of the official maintainer of the debian-nvidia-packages. this way you always get the latest drivers as soon, as they are packaged

but beware: there is currently a bug in nvidia-glx-dev
- run \"./updater -auto\" in you planeshift-directory. sorry if i annoy you with this, but you didn\'t yet say you ran the updater
