Disable all screen savers before testing any graphics device. To disable the Solaris screen saver, type the following at a UNIX prompt:
# xset s off |
The display resolution must be 1024x768 or higher (the standard resolution). To change resolution, go to a UNIX prompt and type:
# fbconfig -res 1280x1024x76 |
Do not run Open Windows across multiple monitors while running ifbtest. The test will return errors.
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.
