Tried to install old nVidia 173 drivers over 177.82 version.

Ubuntu 8.10

Attempting to resolve a continual signal 11 error bug that crashes Wolfenstein: Enemy Territory, I upgraded to the newest stable release of nVidia drivers (177.82). Since this did not fix the problem, I decided to try an older nvidia driver (173), but the application failed and did not show any error output.
