After a recent update the nVidia driver stopped working and now I get the following error message:

NVRM: The NVIDIA GeForce2 MX/MX 400 GPU installed in this system is
NVRM: supported through the NVIDIA 1.0-96xx Legacy drivers. Please
NVRM: visit http://www.nvidia.com/object/unix.html for more
NVRM: information. The 1.0-9755 NVIDIA driver will ignore
NVRM: this GPU. Continuing probe...
NVRM: No NVIDIA graphics adapter found!
FATAL: Error inserting nvidia (/lib/modules/2.6.18-4-k7/nvidia/nvidia.ko): No such device

I installed the nvidia-kernel-legacy but now glx doesn't work. Is there anything I can do to fix this?

Are you using "nv" or "nvidia" in your xorg.conf? For "nvidia" go to the nvidia site and get driver 9631 from the archives and install that. For "nv" I dunno.

Looking at this line,

FATAL: Error inserting nvidia (/lib/modules/2.6.18-4-k7/nvidia/nvidia.ko): No such device

i would guestimate that you're running the nvidia drivers from the site or you have the nvidia kernel modules installed.
Another assumption would be that the update you did included a linux-image package for your machine (2.6.18-4-k7).
If you did run the nvidia drivers from the site, rerun them after linux image package updates as the new image will generally delete the old kernel directories and replace them with new ones from the linux-image and linux-headers/sources package. This deletes the old installed nvidia files needed for the kernel.
If you installed nvidia the debian way, uninstall the nvidia kernel packages first and then re-install them.

Hope this helps.

Re looking at all of the errors tells me that you have installed the wrong drivers as well, you should be using nvidia legacy drivers, not the normal build used for newer video cards. Somewhere on your system is leftovers from the 1.0-9755 series driver which is causing even more problems for you.
The 1.0-9755 NVIDIA driver will ignore this GPU. Continuing probe...
