sudo without having to type a password

[lilcreep]

Hi,

my notebook with hybrid graphics starts with on-chip-graphics in use, but both graphic chips powered.
To safe battery power, I want to use a script, executed on startup:

Code: Select all

sudo -s
echo OFF > /sys/kernel/debug/vgaswitcheroo/switch
exit
exit

Problem is, that this script will ask for my user-password.
How can I do thatfully automatic, without any thing bugging me.

Try to put this line :

Code: Select all

echo OFF > /sys/kernel/debug/vgaswitcheroo/switch

before the line

Code: Select all

exit 0

in the file at the following path : /etc/rc.local

/etc/rc.local

You can run a command with sudo in a script if you want:

Code: Select all

echo "password" | sudo -S command

/etc/rc.local

That's exactly what I said
