Warning: The Nouveau driver doesn't support multiple video cards, nor does it support "display port" devices. If you connect a display port device, the system with crash. Therefore, you might have to install the nvidia drivers if you requir using display port devices.
For information of Nouveau suppoprt for display port devices, see https://fedoraproject.org/wiki/Features/NouveauDisplayPort#DisplayPort_support_for_Nouveau.
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.
With Nouveau being tightly integrated into Fedora 12, 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.
- You have to modify the "grub.conf" file for the drivers to be able to load.
Nvidia Display Drivers (Advance Users Only)
Warning: There a bug that causes the system to "slow down" when any screen "leftOf" the primary screen is accessed. The solution is to ensure the primary screen is the further most left screen within the display configuration.
- 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).
- There is a known issues with trying to run the nvidia driver with the default nouveaudriver. A work around, as stated in http://www.nvnews.net/vbulletin/showthread.php?t=141586 and http://linuxsoftwareblog.com/blog/?p=232 is to add the following rdblacklist=nouveau vga=0×318 to the end of the kernel line in the /etc/grub.conf file. Example:
title Fedora (22.214.171.124-166.fc12.x86_64)
kernel /vmlinuz-126.96.36.199-166.fc12.x86_64 ro root=/dev/mapper/vg_jastest2-lv_root LANG=en_US.UTF-8 SYSFONT=latarcyrheb-sun16 KEYBOARDTYPE=pc KEYTABLE=us rhgb quiet rdblacklist=nouveau vga=0x318
- 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.
