Hi Miroslav,
i'm taking suspend-devel into cc:, maybe somebody there has an idea about
this, too.

Hi,
I'm installing opensuse 10.2 on Fujitsu Siemens Lifebook 7110 (intel
dual core, intel 965 chipset, intel 945 graphics chipset ...).
Most of hardware works fine, but I have some problems with suspend to
ram - suspend/resume using s2ram works fine, but display remains nearly
black. I can see very hardly what's on display, but machine including
network works fine.
So the graphics card is back up, it is really just the backlight that stays
off.
I have tested s2ram on Suse 2.6.18.2-23-default or vanila 2.6.19+swsusp2
with the same problems.
s2ram -i returns
This machine can be identified by:
sys_vendor = "FUJITSU SIEMENS"
sys_product = "LIFEBOOK S7110"
sys_version = " "
bios_version = "Version 1.18 "
s2ram -f -a[0123] gives the same result, -s -p combinations doesn't work
too. Switching back to text console doesn't help. Using xset dpms force
off doesn't help too. The same problem I have both on text console and
using Xserver.
Does this machine have fn-keycombos for adjusting the screen brightness?
Try those. I have seen a FSC Q-series (?) that needed just one touch of
the brightness-up key to turn back on the light.
Once we realized this, we could also poke it via the ACPI video module
(just increase the brightness by one level, then decrease it again) and
this also switched the light back on.
Fn-brightness-down (really down, not up) helps me with the same problem
on older Lifebook S7020 (i915 chipset). However, on Lifebok S7110 non of
Fn- keys or switching off/on display does the same trick :-(
