Description
This test case tests whether screen saver and DPMS work successfully with the Intel video driver, with kernel mode setting enabled. You must be using a video adapter supported by the driver, and Fedora 11 or later (or Rawhide from any time after mid-February 2009).
How to test
- Ensure the 'nomodeset' kernel parameter is not enabled in your bootloader configuration
- Ensure the file /etc/X11/xorg.conf does not exist, or is a known-good configuration file that uses the 'intel' driver
- Shut your system down entirely, then start it up again
- Run gnome-screensaver-preferences
- 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
- Click 'Power Management', and set the 'Put display to sleep when inactive for:' timeout to the minimum (six minutes)
- Leave the system idle for longer than six minutes
Expected Results
- The screensaver should activate after a minute, and the display should blank after six. It should recover correctly when the mouse is moved
