uname -a
Linux mandachuva 2.6.22.9-cfs-v22 #2 PREEMPT Sun Sep 30 15:21:17 BRT
2007 i686 GNU/Linux
Distro: Debian Etch
When I use KPowersave and click on "Suspend to RAM", my laptop Toshiba
M45-S355 "sleep" and "wake-up" very well, but LCD Brightness is changed
to MAX (I hate this "sunshine" on my eyes).
One more detail: Kernel Linux don't have control of lcd brightness, so I
need use omnibook driver to do this (<http://omnibook.sourceforge.net>).

Renato

Well, that probably is the reason why the brightness changes after a resume.
As a workaround you can probably use a wrapper script to set the brightness
to the desired level after a resume from RAM.
