Toshiba sucks for Ubuntu 10.04LTS, my eyes are getting blow up, because of the fu...ing screen brightness can't be set with: $> toshset -lcd [0,1...7] by default. I'm still looking for ways to surpass this limitation... If you know something about it please let me know in a comment an url anything to get this thing done!! Para la version 12.04 de ubuntu este comando funciona a la perfección además de que las teclas de brillo fn-f6-f7 también funcionan $>echo "3" | sudo tee /sys/class/backlight/acpi_video0/brightness
