Hello,
On a Toshiba Portege R700 laptop, the backlight control works fine, until a
suspend, and does not work post suspend to RAM/resume.
Tested in single user mode, manipulating
/sys/class/backlight/toshiba/brightness directly, using /sys/power/state to
trigger suspend; as well as gnome-power-manager invoked suspend in a multiuser
mode GNOME desktop session.
