There is a related bug on the kernel bug tracker:
https://bugzilla.kernel.org/show_bug.cgi?id=21012 for Kernel 3.2.
I tried the workaround suggested in comment 19 but this stops my laptop
going in sleep mode.
Any ideas how to modify this script to make it work?
-----------------
#!/usr/bin/env sh
# /etc/pm/sleep.d/99toshiba
if [ $1 == suspend ]
then
cat /sys/class/backlight/intel_backlight/brightness >
/var/run/brightness
elif [ $1 == resume ]
then
echo 3 > /sys/class/backlight/toshiba/brightness
cat /var/run/brightness >
/sys/class/backlight/intel_backlight/brightness
fi
