How do I configure xorg for Nvidia: using KDE 4.4.5
 

Using Debian Squeeze.
KDE 4.4.5

I have downloaded a driver from Nvidia:
NVIDIA-Linux-x86-71.86.14-pkg1.run

I don't see an /etc/xorg.conf file. How do I configure xorg after I install the driver?

Thanks

Step1: delete the file "NVIDIA-Linux-x86-71.86.14-pkg1.run"

Step2: install dkms, nvidia-settings and nvidia-xconfig
(you will need Debian contrib and non-free repositories to do so)

Step3: install nvidia-kernel-dkms
In case you use synaptic, make sure you can see the console output of the install procedure. dkms is meant to auto-compile proprietary modules like "nvidia" for any new kernel installed. For me, this didn't work out of the box - dkms complained about something missing ... I think it were the kernel headers or something like that. Nothing to complicated, but keep an eye on it. If dkms complains, install whatever dkms misses, remove nvidia-kernel-dkms and install it again.

Step4: run nvidia-xconfig as root

Step5: restart your X server and run nvidia-settings

maybe you want to install nvidia-glx for 3D acceleration and nvidia-vdpau-driver for video decoding.

the file is located at /etc/X11/xorg.conf
