Setting default brightness level on startup for all run leve

Laptop: Toshiba R630
OS: Linux Mint 14 Cinnamon

I have seen various articles (http://askubuntu.com/questions/151651/b ... ry-restart) on adjusting brightness. But my laptop seems to have more than one way to adjust brightness using /sys fs.

/sys/class/backlight$ ls -l
total 0
lrwxrwxrwx 1 root root 0 Feb 24 11:56 acpi_video0 -> ../../devices/pci0000:00/0000:00:02.0/backlight/acpi_video0
lrwxrwxrwx 1 root root 0 Feb 24 12:18 intel_backlight -> ../../devices/pci0000:00/0000:00:02.0/drm/card0/card0-LVDS-1/intel_backlight
lrwxrwxrwx 1 root root 0 Feb 24 12:18 toshiba -> ../../devices/LNXSYSTM:00/device:00/TOS6208:00/backlight/toshiba


1. why is there more than one way? what is the difference between them?
2. which is the preferred way to set initial brightness for all run levels?
3. how does toshset get installed? i dont remember installing myself. Does Mint install based on identified manufacturer?

$ dpkg -l | g toshset
ii toshset 1.76-4 amd64 Access much of the Toshiba laptop hardware interface

$ dpkg -L toshset
