To check if this is working or not just execute glxgears, it should report the same FPS as your monitor Hz (60 typically). $ glxgears Running synchronized to the vertical refresh. The framerate should be approximately the same as the monitor refresh rate. 300 frames in 5.0 seconds = 60.000 FPS ... If you don't have it enabled, the way to enable it under compiz is: * Install the package compizconfig-settings-manager. * Execute ccsm. ** Under the category General, select General Options. Select the Display Settings tab. De-select the Detect Refresh Rate option. Set the Refresh Rate option to match the vertical refresh rate of your display. (I checked my monitor’s on-screen display to verify that it was running 60 Hz.) Finally, select the Sync To VBlank option. This should fix the issue Regards!
