Description
This test case tests whether fast user switching 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
- Ensure the 'nomodeset' kernel parameter is not enabled in your bootloader configuration
- Ensure the file /etc/X11/xorg.conf does not exist, or is a known-good configuration file that uses the 'intel' driver
- Shut your system down entirely, then start it up again
- Create a second regular user account, if you do not already have one available. If you are using a live image, either change the password of the 'liveuser' user to something you can use, or create two regular user accounts to test with, then log in as the first
- Trigger fast switching (in a default Fedora desktop, click your name at the top right hand corner, then select Switch User)
- Log in with the second user account
- Test switching from one account to the other and back again, with both logged in
- Check the GLX and Xv test cases on both logins
Expected Results
- Fast user switching should work correctly, with no display issues on either desktop
- Accelerated OpenGL apps and video playback should work on both desktops when two logins are active
- If you are using the Test Day live CD image, you may see xkb errors when switching user - this is a known bug and does not need to be reported
