Preparation for ifbtest

You should complete a few steps in advance to ensure that ifbtest runs as smoothly as possible.

If you are running ifbtest in a window system (such as CDE or OPEN LOOK):

• Turn off Power Management if it is enabled.

• Make sure that no other program is running that might modify the screen during the test.

• Make sure you have permission to lock the X server. ifbtest is designed to lock the X server during testing to prevent screen changes.

• The CDE login window should not be displayed during testing.

• Check that the window system is only running on one Expert3D frame buffer.

If you are not running ifbtest in a window system:

• Turn off Power Management if it is enabled.

• Make sure that no other program is running that might modify the screen during the test.

• Make sure the Expert3D frame buffer being tested is not the console device. Console messages may modify the screen.
