More info regarding Toshiba Satellite R830:

I can't change brightness after returning from sleep with Fn-keys, but echoing numbers to /sys/class/backlight/intel_backlight/brightness does change the brightness properly.

It seems that Fn keys write to /sys/class/backlight/acpi_video0/brightness, which doesn't do anything.
Perhaps a fix could be made in Unity (or gnome power manager) to prefer intel_brightness if it's available?
