Description

This test case tests whether multiple displays work successfully with the Radeon driver. You will need at least two monitors connected to your Radeon video adapter to perform this test.


How to test

  1. Connect as many displays as you can to the available ports on your display adapter
  2. Ensure the 'nomodeset' kernel parameter is not enabled in your bootloader configuration (unless you need it for basic X operation to suceed)
  3. Ensure the file /etc/X11/xorg.conf does not exist, or is a known-good configuration file that uses the 'radeon' driver
  4. Shut your system down entirely, then start it up again
  5. Verify that the graphical environment starts correctly and shows the same screen on each display (clone mode)
  6. Open a console and run the command xrandr. Take a copy of the results
  7. Run the GNOME display configuration tool, gnome-display-properties. Verify that it correctly shows each of the connected displays (monitors). Test re-arranging, enabling, disabling and configuring displays

Expected Results

  1. xrandr should report each connected display and the correct available modes on each
  2. gnome-display-properties should allow you to arrange the displays in any configuration, enable and disable displays, and change each display's settings; these changes should work and be reflected in what each display actually shows
