For this we use 2 little utilities called glmark2 and glxgears. It might be interesting to compare the graphics performance with different drivers and to ensure that the gpu is indeed performing well. The official nvidia drivers would make the gpu deliver its full performance. However with the Nouveau driver the gpu cannot perform to its full potential and features like hardware 3d acceleration would be unavailable or limited. ![]() The last line indicates the kernel driver in use, which is nouveau over here.

Nouveau - the default driverįor Nvidia GPUs, the Nouveau driver becomes active by default. ![]() Otherwise the performance would be limited, or totally unused. It is necessary to install the right drivers to ensure proper utilisation GPU. Nvidia GPUs are very popular on desktop computers and they work very well on linux, as drivers are available from Nvidia.
