xfree86: Use "Ignore" option in InputClass to skip devices
Sometimes it is desirable to skip adding specific input devices to the server. The "Ignore" option is used similarly to Monitor sections so that matched devices will not be added. BadIDChoice is returned to the config backend so that it will clean up all resources. Signed-off-by: Dan Nicholson <> Reviewed-by: Peter Hutterer <> Signed-off-by: Peter Hutterer <>
