Installing CUDA capable driver for Quadro FX 5800

I am trying to install a CUDA capable driver on 64-bit ubuntu 8.04 with an LCD monitor connected to a Quadro FX 5800. I’ve tried it with different LCD monitors (Samsung SyncMaster 245BW, Samsung SyncMaster 206BW, and a Dell monitor), but they are unable to sync with the Quadro. When I connect a CRT to the Quadro, it works fine.

Here’s what I’ve done:

  • add DISABLED_MODULES=“nv” to /etc/default/linux-restricted-modules-common

  • /etc/init.d/gdm stop

  • install

  • /etc/init.d/gdm start

The computer hangs here and tries to go into Low Graphics Mode

nvida-xconfig provides me with the following /etc/X11/xorg.conf:

I’ve tried changing it to:

Can anyone help me with this?

Thanks in advance.


The display works now.
I think what I did was:

  • remove all nvidia related drivers/modules
  • uninstall glx
  • connect the monitor to the bottom VGI
talks about a lot of this.
