This test case tests whether accelerated OpenGL applications under compositing managers work with the Radeon video driver, with kernel mode setting enabled. You must be using a card supported by the Radeon video driver.
- Ensure the 'nomodeset' kernel parameter is not enabled in your bootloader configuration (unless you need it for basic X operation to suceed)
- Ensure the file
/etc/X11/xorg.confdoes not exist, or is a known-good configuration file that uses the 'radeon' driver
- Ensure that
and related packages are installed by running the command:
su -c "yum install gnome-shell desktop-effects"
- Ensure the
package is installed by running the command:
su -c "yum install glx-utils"
- Shut your system down entirely, then start it up again
How to test
- Enable GNOME Shell by selecting System → Preferences → Desktop Effects and selecting the GNOME Shell option
- Run the command
glxgears(or, optionally, any other OpenGL app you can think of)
- Try covering the glxgears window with other windows
- Move the glxgears window around
- Activate the Shell's overview mode (press the Super (aka Windows) key, or move the mouse to the top left hand corner of the screen), and deactivate it (same procedure)
- OpenGL apps should run properly and with full acceleration and behave as any other window. Covering them should work properly, they should move smoothly, and should render properly in the overview mode. Overview mode should activate quickly with a smooth transition, and deactivate in the same way. There should be no glitches or corruption in the display of the desktop or overview mode with GNOME Shell enabled
