On my Dell D600 and the 422 kernel I can suspend and resume my laptop. (After unloading some USB stuff). However when I resume the video display shows only coloured vertical lines and the backlight slowly increases in brightness. I have seen references to some patches to help Radeon video cards return from sleep. DO I need to find these and apply them somewhere to make S3 work? I am guessing I resumed because C-A-D will reboot the laptop. Video card is: 01:00.0 VGA compatible controller: ATI Technologies Inc Radeon R250 Lf [Radeon Mobility 9000 M9] (rev 02) Thanks, Philip
