Description

This test case tests whether multiple displays work successfully with the software rendering, and whether desktop environments handle multiple displays correctly. You will need at least two displays connected to your video adapter to perform this test.

Setup

  1. Connect as many displays as you can to the available ports on your display adapter.

How to test

  1. Verify that the graphical environment starts correctly and is spanned across all connected displays
  2. Open a console and run the command xrandr. Take a copy of the results
  3. Disconnect and then re-connect one or more displays; do this several times. If you are using a docking station for a laptop, try removing the laptop from and restoring the laptop to it several times
  4. Run your desktop's display configuration tool. For GNOME 3 this is gnome-control-center display. 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. Both X and the graphical environment should cope smoothly with displays being disconnected and reconnected while the system is running: the displays should be correctly added or removed by X, and the graphical environment should correctly adjust itself to the added or removed display
  3. Configuration tools 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
