Description

This test case tests whether accelerated OpenGL applications under compositing managers work with the intel video driver. You must be using a card supported by the intel video driver.

Setup

  1. Ensure that you are using Fedora Workstation (or at least GNOME)
  2. Ensure the glx-utils package is installed by running the command: su -c "dnf install glx-utils"
  3. 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
  4. Ensure the file /etc/X11/xorg.conf does not exist, or is a valid file that uses the intel driver
  5. Shut your system down entirely, then start it up again
  6. 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 command glxinfo | grep renderer and verify that an accelerated 3D driver is in use (ie, not llvmpipe)
  2. Run the command glxgears (or, optionally, any other OpenGL app you can think of)
  3. Try covering the glxgears window with other windows
  4. Move the glxgears window around
  5. 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)

Expected Results

  1. glxgears (and other OpenGL apps) should run properly and with full acceleration and behave as any other window
  2. Covering them should work properly, they should move smoothly, and should render properly in the overview mode
  3. Overview mode should activate quickly with a smooth transition, and deactivate in the same way
  4. GNOME should run successfully and there should be no glitches or corruption in the display of the desktop or overview mode
