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=:0glxgears is a simple utility to test 3D Accelerationglxgears is a simple utility to test 3D Acceleration (local host)
