(1) To reproduce this:

Set up:

* Install nvidia-current (I used Synaptic).

* Ensure that /etc/X11/xorg.conf does not exist (delete it if necessary).

* Reboot and login in. At this boot you should be using the nouveau driver because xorg.conf is not specifying nvidia. Confirm that the nvidia module is loaded with:

lsmod | grep nvidia

Reproduction of problem:

* Run gnome-display-properties, either from the command line, or via the System / Prefs / Display menu option.

(2) What should happen:

gnome-display-properties should display its standard window and allow you to change screen resolution, etc, as it does after a fresh installation.

(3) What actually happens:

gnome-display-properties says:

"It appears your graphics driver does not support the necessary extensions to use this tool. Do you want to use your graphics driver vendor's tool instead? No / Yes."

This is the message it normally displays when you *are* running the nvidia module.

Note that it tells the truth - if you select 'No' and continue to use gnome-display-properties, it does not detect monitors or change screen resolution.

However, if you select 'Yes' and have it run nvidia-settings, nvidia-settings says you aren't using the nvidia module and it can't do anything either.
