C’est une très bonne idée.
J’ai installé manuellement nvidia-settings, via un .deb. En exécutant nvidia-settings, je reçois le message ``You do not appear to be using the NVIDIA X driver. Please edit your X configuration file (just run nvidia-xconfig as root), and restart the X server.’’ Le problème, c’est que ça ne me reconna^it pas la commande, lorsque je tape nvidia-xconfig. Du coup, je me suis dit qu’il était peut-^etre bien d’installer nvidia-glx. Ce n’est pas si simple, puisque # dpkg -i nvidia-glx_173.14.09-5_i386.deb
Selecting previously deselected package nvidia-glx.
(Reading database ... 174311 files and directories currently installed.)
Unpacking nvidia-glx (from nvidia-glx_173.14.09-5_i386.deb) ...
dpkg: dependency problems prevent configuration of nvidia-glx:
nvidia-glx depends on nvidia-kernel-173.14.09; however:
Package nvidia-kernel-173.14.09 is not installed.
Pas un problème: [code]
apt-get -s install nvidia-kernel-173.14.09
Reading package lists… Done
Building dependency tree
Reading state information… Done
Package nvidia-kernel-173.14.09 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
[/code]
Il faut rester calme! 
Je télécharge nvidia-kernel-173.14.09. Pas de chance, il faut nvidia-kernel-common. Je l’installe. J’installe tout, dans le sens inverse, forcément. Tout va bien, mais [code]
nvidia-xconfig
bash: nvidia-xconfig: command not found
[/code]
Il fallait simplement installer nvidia-xconfig. Je l’installe. Du coup,
# nvidia-xconfig
Using X configuration file: "/etc/X11/xorg.conf".
VALIDATION ERROR: Data incomplete in file /etc/X11/xorg.conf.
At least one Device section is required.
Backed up file '/etc/X11/xorg.conf' as '/etc/X11/xorg.conf.backup'

Est-ce positif? Cela étant, toujours le m^eme message de la part de nvidia-settings. Pourtant,
[code]
cat xorg.conf

Mon intuition m’a dit de redémarrer, et, en redémarrant, tout a fonctionné. Merci!
