Can't install CUDA 2.3 driver


I have the following configuration:

GPU: GForce 8500 GT
OS: UBUNTU 9.04 32 bit
Linux Kernel: 2.6.28-15-generic

I took the following steps:

  1. Downloaded the CUDA 2.3 NVIDA driver 190.18 from This gave me the file
  2. Stopped my window manager.
  3. Ran the driver installer successfully.

But when I went to restart my window manager, the driver crashed. Any idea why this is happening?
