Hmm, not really what we want ...

can you run this (in a console) and send the transcript?

ls -l /dev/nvidia*
invoke-rc.d gdm3 stop
rmmod nvidia
lsmod | grep nvidia
ls -l /dev/nvidia*
modprobe -v nvidia
ls -l /dev/nvidia*
invoke-rc.d gdm3 start

If gdm3 fails to start now, stop here

How does this look with the nvidia packages from jessie-backports?
(340.93-3~bpo8+1)
I'm afraid we could hit the 'adduser *dm video' bug here ... (don't fix
it this way).
