hi i want to know whether my graphic card is installed or not ? when i execute

glxinfo | grep OpenGL

it returns

OpenGL vendor string : Tungsten Graphics, Inc
OpenGL renderer string : Mesa DRI Intel(R) 945GME x86/MMX/SSE2
OpenGL version string : 1.4 Mesa 8.0.5
OpenGL extensions:

so is the Intel(R) 945GME in renderer string means installed ?

  • Looks like. I usually check using "glxinfo | grep direct rendering" (or similar), looking for a line saying "direct rendering: yes/no". You can also check using glxgears, if it shows the gears, you graphic card is installed.

similar to your command glxinfo | grep OpenGL also glxinfo | grep render if you'd like to check a short info on your graphics run:

lspci -nnk | grep -iA2 VGA

if you want to see more advanced output:

sudo lspci -vnnk | grep -iA12 VGA
