Description

This test case tests whether, when using the intel video driver, X can successfully shut down and restart. You must be using a card supported by the intel video driver.

Setup

  1. Ensure the 'nomodeset' and 'i915.modeset=0' kernel parameters are not set in your bootloader configuration
    • You can see your current kernel options by running cat /proc/cmdline
  2. Ensure the file /etc/X11/xorg.conf does not exist, or is a valid file that uses the intel driver
  3. Shut your system down entirely, then start it up again
  4. If using a live image to test, ignore the above steps and simply boot the system from the live image with default options

How to test

  1. Log in to the desktop
  2. Press ctrl+alt+f2: this should switch to a console interface
  3. Log in as root (if you are using the live image, you can do so, there is no password on the root account)
  4. Run the command systemctl stop display-manager.service
  5. If necessary, hit ctrl+alt+f2 again to get back to the console you are using
  6. Run the command systemctl start display-manager.service
  7. If necessary, hit ctrl+alt+f1 to get back to the graphical interface
  8. If necessary (on live images, you may be automatically logged in) log back into the desktop

Expected Results

  1. After running the first command, the graphical desktop should stop running
  2. After running the second command, the graphical desktop should start up again
  3. X should work properly both the first and second times it is started
