Description

This test case tests whether screen saver and DPMS work successfully with 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
