Nvidia GeForce 525M. How can I test whether my GPU is actually working as a GPU, and it's not my integrated graphics/CPU filling in? My CPU load seems unusually high.
Instead of actual driver verification, I'd just like to see some cool 3D stuff that doesn't kill my CPU.
There is a set of utilities, and an information string which provide what you are looking for. They need to be installed... Open a terminal window ctrl+alt+t
Install the utilities
sudo apt-get install mesa-utils
The command glxinfo | more will contain information about how the graphics section looks up. Try glxinfo | grep string - you are not looking for llvmpipe!
A simple test graphics program is glxgears, which will tell you how many frames per second are being generated.
