Description

This library provides hardware-accelerated Direct3D and OpenGL support. This is used by most games, but also by CAD applications and recent Microsoft Office versions.

If the terminal reports this message:

libGL error: unable to load driver: swrast_dri.so
libGL error: failed to load driver: swrast

Your machine has not been configured for DRI rendering. This means applications like PowerPoint 2010 will not launch. Please ensure that you have installed the mesa-dri libraries or reinstall the proprietary drivers to properly configure the system.

Resolution

Each graphics driver comes with a different version of this library. We recommend consulting your distribution's documentation for instructions on how to install the best OpenGL and 3D driver for your graphics card. That said we normally recommend using the fglrx driver for AMD/ATI graphics cards and the nvidia one for Nvidia cards.

Here are some package names that you may use as a starting point. Note that it is important to use the right one to match your graphics driver:

Arch Linux
Intel 32-bit : pacman -Syu xf86-video-intel mesa-libgl
Intel 64-bit : pacman -Syu xf86-video-intel lib32-mesa-libgl

Additional Help

If the distribution-provided graphics packages don't help resolve OpenGL errors the next step is to download the proprietary graphics installers from Nvidia/AMD and manually install them on your system. Nvidia's drivers are located here and AMD's drivers here. Search Google for instructions on how to install these packages directly on your Linux distribution.
