The NVIDIA proprietary driver blacklists the nouveau driver by creating a file in /etc/modprobe.d IIRC the file name is nouveau.conf, but I could be wrong there.
If you want to revert to using nouveau you will have to: (i) remove that file (ii) run sudo depmod -a (iii) rebuild initramfs by running sudo update-intramfs -u -k all (iv) reboot Hope this helps -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
