Hello,

FYI, Jordi's script is configured to work with Adam's kernel only (kernel
which name contains vaioz) ... it will not do anything if you use it with a
2.6.38 kernel, because of (see at the end of the script) :

if uname -r | grep -e "-vaioz$" >/dev/null
then
    [ "$(cat /sys/devices/platform/sony-laptop/speed_stamina)" = "stamina" ]
&& set_alternatives_to_intel || set_alternatives_to_nvidia
fi

Keep that in mind when you are testing the script.
