May be to late to add these question but for my first usage of the command and next the first search about it. what happens when you get these: Eva03:/home/ikari # glxgears Xlib: extension "GLX" missing on display ":0.0". glxgears: Error: couldn't get an RGB, Double-buffered visual. and these: Eva03:/home/ikari # glxinfo name of display: :0.0 Xlib: extension "GLX" missing on display ":0.0". Xlib: extension "GLX" missing on display ":0.0". Xlib: extension "GLX" missing on display ":0.0".

glxgears is not meant to be used as a benchmark, it's only a quick way of seeing if you have 3d acceleration active at all. You really can't use those FPS numbers as a measurement of how fast your card is
if "glxinfo|grep rendering" says "yes", then you have 3d acceleration.
