Determine OpenGL versionDetermine OpenGL version (from CLI on local machine... not remote ssh)glxgears is a simple utility to test 3D AccelerationTo exercise use of glxinfo via ssh session to a remote machine, two things will have to be applied. Firstly, if you see the error ( Error: unable to open display ) then you did not allow x-forwarding on your ssh session. Initiate SSH like this: ssh -X remotehostThe -X allows x-forwarding. Secondly, AND VERY IMPORTANT, executing the command now will falsely report glxinfo because it will still reference your local host even though you are at the remote CLI. Now to specify which display (the correct remote display) execute the command: DISPLAY=:0 glxinfo | grep "OpenGL version" glxgears is a simple utility to test 3D Acceleration (local host)
