Never worked with any kernels tested (2.6.22, 2.6.23) Distribution: Debian Unstable Hardware Environment: Fujitsu Lifebook T2010, i965 graphics. Problem Description: After suspending, the backlight fails to resume in both the raw console, and Xorg. There is more information available at this bug: http://bugs.freedesktop.org/show_bug.cgi?id=13709. The kernel exposes no backlight controls for this machine, and the X methods fail to bring back the backlight, with the exception of the native method iff I change the driver to make it default and I restart X after resume. Steps to reproduce: "echo mem > /sys/power/state", hit the power button, and note the screen is on, and everything but the backlight has resumed.

Ori, could you please attach: 1) output of acpidump 2) dmesg 3) lspci -vvxxx
Created attachment 14591 [details] acpidump output

ACPI has no influence on backlight restore, it is the job of the video driver, and failing that, the BIOS; so I'm moving this sighting from ACPI/suspend to PowerManagement/suspend Please try the "s2ram" application, as it has a number of workarounds for this issue built into it. If s2ram doesn't know about this laptop, you can try the workarounds manually. They are listed in: Documentation/power/video.txt
Erm...mine works fine with kernel 2.6.24. http://www.digriz.org.uk/debian-fujitsu-t2010
Ori, can you verify as Alex said in comment# 6?
