This test case tests whether screen saver and DPMS work successfully with the Radeon video driver, with kernel mode setting enabled. You must be using a card supported by the Radeon video driver.

How to test

  1. Ensure the 'nomodeset' kernel parameter is not enabled in your bootloader configuration
  2. Ensure the file /etc/X11/xorg.conf does not exist, or is a known-good configuration file that uses the 'radeon' driver
  3. Shut your system down entirely, then start it up again
  4. Run gnome-screensaver-preferences
  5. Select a screensaver, set the "Regard the computer as idle after:" timeout to one minute, and ensure 'Activate screensaver when computer is idle' is checked
  6. Click 'Power Management', and set the 'Put display to sleep when inactive for:' timeout to the minimum (six minutes)
  7. Leave the system idle for longer than six minutes

Expected Results

  1. The screensaver should activate after a minute, and the display should blank after six. It should recover correctly when the mouse is moved
