Description
This test case tests whether multiple displays work successfully with the Nouveau driver. You will need at least two monitors connected to your NVIDIA video adapter to perform this test.
How to test
- Ensure the file
/etc/X11/xorg.conf
does not exist, or is a valid file that uses the nouveau driver. If you are using the live image, ignore this step - Connect as many displays as you can to the available ports on your display adapter
- Shut your system down entirely, then start it up again
- 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)
- Open a console and run the command xrandr. Take a copy of the results
- 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
- xrandr should report each connected display and the correct available modes on each
- 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
