This test case tests whether multiple displays 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

  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 'intel' driver
  3. Shut your system down entirely, then start it up again
  4. Verify that the graphical environment starts correctly and is spanned across all connected displays (Fedora 12 and later) or shows the same output on all displays (Fedora 11 and earlier)
  5. Open a console and run the command xrandr. Take a copy of the results
  6. 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. Note that you cannot exceed 2048 pixels vertically or horizontally on i945 and earlier chips (for i965 and later, the limit is 8192). Also note that TV outputs are disabled as of 2009-03-11 because they otherwise always show up.
