May I know how I could tell if graphics processing (3D, video encode/decude) in Ubuntu is utilizing hardware acceleration (ie. using GPU). Is there a utility to tell? Thank you for the suggestions and pointers.

you can use glxinfo to test if your X server is using the GPU driver. glxinfo queries X server about its OpenGL version, renderer string, Visuals supported and other infomation.

glxinfo | less

Even I had this doubt. So what am I supposed to look at in the output of this command? –  ganezdragon Apr 30 at 6:06
    
OpenGL version, vendor string, renderer string. then you'll know if you're running open source drivers or proprietary drivers or software rasterizers. –  sgx1 Apr 30 at 6:18
    
ok thank you... –  ganezdragon Apr 30 at 8:13

Try the following command if you're running Unity:

/usr/lib/nux/unity_support_test -p

It will tell you if you're using a Software renderer.
