This test case tests whether DPMS functionality works successfully with the (DRIVER) video driver. You must be using a card supported by the (DRIVER) video driver.


  1. Ensure the nomodeset and (MODULE).modeset=0 kernel parameters are not set in your bootloader configuration
    • You can see your current kernel options by running cat /proc/cmdline
  2. Ensure the file /etc/X11/xorg.conf does not exist, or is a valid file that uses the (DRIVER) driver
  3. Shut your system down entirely, then start it up again
  4. If using a live image to test, ignore the above steps and simply boot the system from the live image with default options

How to test

  1. Run the command sleep 5 && xset dpms force off

Expected Results

  1. After 5 seconds the display should blank. It should recover correctly when the mouse is moved
