1) Install debian nvidia pkgs using your favorite method (aptitude, synaptic, apt-get...)
these 3 packages should pull in all the required dependancies:
2) blacklist the nouveau module
edit /etc/modprobe.d/blacklist.conf (create it if it doesn't exist) and add these lines
blacklist nouveau
options nouveau modeset=0
The first line prevents the module from being loaded at boot; second line prevents the nouveau module from doing a kernel modeset if it somehow gets loaded otherwise.
3) This may be unnecessary, but I do it for completeness, in case the nouveau module might get loaded during boot by the initramfs:
~# sudo update-initramfs -u -k all

This comes up with 8 lines something like this:
W: possible missing firmware /lib/firmware/rt1_nic/rt18168f-2.fw

all lines end in that rt18168 except one which is rt18105e

~# sudo update-grub
This, of course, assumes you use grub to boot, so if you use lilo or something else, you will have to make sure it is properly updated as to the location of the initramfs file.
This is often hard coded by the boot loader.
3) Reboot and even if something tries to load the nouveau module, the 'modeset=0' line will enable you to properly unload the module.

So still no joy (actually less than before as I did not back up the xconf that was working but I think it was xrandr but it doesn't want to work now so things are a wee bit fubared at present.

Any ideas - please?
