I have found no way to turn off the screen completely while in supsend. However I have only tried 2 of the 3 sysctls mentioned by Kevin... I remember it all working under 4.x with APM. I guess I will give that a try again. Despite these problems, there are some Thinkpads, which are know to work with acpi. One trick is disabling dri in the kernel / X-Config. This prevents the system from loading the radeon.ko module, that is likely to cause this problem whith the background light. Didn't work here, maybe you are lucky... Cheers, Jochen
