Description

This test case tests whether display rotation work successfully with the (DRIVER) driver. You must be using a card supported by the (DRIVER) video driver.

Setup

  1. Ensure the nomodeset and (MODULE).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 (DRIVER) 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. Run the GNOME display configuration tool using gnome-control-center display. Try rotating the primary display - change the Rotation drop down and hit apply
  2. Try and change back to the normal orientation

Expected Results

  1. The rotation should apply correctly and the rotated screen should display with no artifacts. Returning to the normal orientation should also work smoothly with no artifacts
