Comment 17 for bug 300476

Sadly, I don't have any cards that are supported by both drivers.

I see there is an older version of nvidia-glx-96 available
( http://packages.ubuntu.com/intrepid/nvidia-glx-96
vs. http://packages.ubuntu.com/intrepid-updates/nvidia-glx-96 )
but I can't figure out how to install it; I tried downloading
its three files and doing
  sudo dpkg -i nvidia-96-kernel-source_96.43.05-0ubuntu10_i386.deb nvidia-glx-96-dev_96.43.05-0ubuntu10_i386.deb nvidia-glx-96_96.43.05-0ubuntu10_i386.deb
but this failed with
 Error! Bad return status for module build on kernel: 2.6.27-7-generic (i686)
 Consult the make.log in the build directory
 /var/lib/dkms/nvidia/96.43.05/build/ for more information.
That file had lots of compile errors, e.g.
In file included from /var/lib/dkms/nvidia/96.43.05/build/nv.c:14:
 /var/lib/dkms/nvidia/96.43.05/build/nv-linux.h: In function ‘nv_execute_on_all_cpus’:
 /var/lib/dkms/nvidia/96.43.05/build/nv-linux.h:620: error: too many arguments to function ‘on_each_cpu’

So I guess the easiest path would be to try a fresh install of
*non-updated* Intrepid. If that doesn't have the problem,
then the likely culprit is the newer nvidia-96 version in intrepid updates.
