Graphics driver

Many desktop environments need a graphics driver to work properly. Install Mesa drivers for all graphics cards before installing a desktop:

• mesa-dri-gallium: necessary Mesa drivers for all Graphics cards.

Mesa-dri-gallium is an open-source OpenGL implementation that supports a variety of hardware and software drivers, including Intel, AMD, NVIDIA, and more.

Graphics cards of recent vintage need a driver to work. So install additional graphics drivers from the below depending on your hardware. Information about the video cards that are installed in the computer may be found using lspci command, which is not available by default. Refer the instructions to install pciutils package.

To identify the graphics card (the Subsystem output shows the specific model), issue the below command:

lspci -v | grep -A1 -e VGA -e 3D

Then, install an appropriate driver.
