Some graphics hardware (aka video cards) may need restricted (non-Free) drivers, even though these drivers are not part of the open source community and cannot be fixed by open source software developers. If you encounter bugs with these closed-source drivers, developers will not be able or even willing to assist you in resolving your issues. Use at your own risk.
Should I install a restricted video driver?
The answer to this question is dependent on what video card you have, what you want to do with it, and (perhaps most importantly) personal choice. To determine exactly which video card you have, open a Terminal and enter this command:
lspci | grep VGAThat will return something similar to:
01:00.0 VGA compatible controller: ATI Technologies Inc Radeon Mobility M7 LW [Radeon Mobility 7500]
From this output, you should be able to discern your video card brand and model to choose the proper section below. (!) The following sections refer to video drivers first by their package name, then by the identifier in parentheses. The identifier is how the driver is named in the xorg.conf and when reconfiguring X, and is how the driver is referred to afterward whenever possible.
Intel
If you have an intel video chip, you do not need a restricted video driver. Intel's official driver is Free Software (open source) and is bundled with Ubuntu (and most other distributions). There are two intel drivers available:
- xserver-xorg-video-i810 (identifier: i810) - This is the intel driver included in all ubuntu versions up to 7.04 (Feisty).
- xserver-xorg-video-intel (identifier: intel) - This is a newer version of that driver which adds better resolution-setting support. It is available in Feisty's Universe component for those who wish to try it and will be default in Ubuntu 7.10 (Gutsy).
<!> Installing the binary NVIDIA or ATI driver will only break the 3d acceleration provided by the Intel driver.
NVIDIA
Ubuntu ships with the open source xserver-xorg-video-nv driver (identifier: nv). This driver does not provide 3d acceleration, and lacks support for other aspects of NVIDIA hardware. To install the restricted NVIDIA driver, see UbuntuHelp:RestrictedDrivers/NVIDIA.
ATI
Ubuntu ships with the open source xserver-xorg-video-ati driver (identifier: ati). This driver provides 3d acceleration through the Radeon X850. (R100 to R400 chips). For newer cards, you must use the ATI restricted driver, xorg-driver-fglrx (identifier: fglrx) <!> Installing fglrx on a card older than the Radeon 9500 will only break your 3d acceleration with the free ati driver To install the restricted ATI driver (fglrx) and to determine whether to use it: see UbuntuHelp:RestrictedDrivers/ATI.
