Getting the Display to Work

Warning: The Nouveau driver doesn't support multiple video cards.

With previous versions of Fedora, especially Fedora 8 and earlier, it was found that there was a need to install the appropriate graphics driver to allow the ability to “span” the desktop across multiple screens and also allow 3D acceleration.  Note that 3D support isn't as good when compared to the nvidia drivers (glxgears provides an example for framerate comparsion).

With Nouveau being tightly integrated into Fedora 13, there appears that it might be acceptable to use in some cases. For more information on nouveau, see http://nouveau.freedesktop.org/wiki/. Additionally it has been found that there are a few minor issues with using the nvidia drivers.

Some that have be issues tested and confirmed include:

  • Using gnome remote desktop (vin0-server), the nvidia drivers have problems and only "refreshes" the primary screen.

Nvidia Display Drivers (Advance Users Only)

  • Ensure you have the RPM Fusion repo installed, as given on "Update of Fedora Linux for latest Software and Patches".
  • Start up a terminal, and as "Super User", issue the command yum install akmod-nvidia (For very old nvidia cards, you might have to use the akmod-nvidia-96xx package).
  • Note that installing the above package, the following arguements are added to the kernel line within the /etc/grub.conf file, these being nouveau.modeset=0 rdblacklist=nouveau
  • Once installed, a reboot of the machine is recommended to allow the nvidia kernel modules to load.

Adjusting the Resolution and other Display Properties

If using a NVIDIA display card with the NVIDIA drivers, it is suggested to use the nvidia-setttings program to configure the display properties.

To use this program, simply:

  • Start up a shell terminal as "root" or "superuser".
  • Issue the command nvidia-settings
  • Then to change display propertities, simply select the "X Server Display Configuration" as can be seen in the below image.
