Yeah its a bit confusing since Im new to this, but I'll give a look and try it when i get it.

Seems like I'll have some questions but we'll see. I'll post here results when done.

Thanks alot for fast replays and your time! Cheers!

Sorry this has been such a pain, but the manufacturers have not made this a priority for Linux, so we are left with some frustrating results.

True. Its kinda annoying sometimes but it is what it is. I hope they will change mind and do something for Linux users.

Anyway I took a try at

https://help.ubuntu.com/community/HybridGraphics#Enabling_vga_switcheroo

So I started at section "Enabling vga_switcheroo":

:~$ grep -i switcheroo 
/boot/config-*/boot/config-3.11.0-19-generic:CONFIG_VGA_SWITCHEROO=y
/boot/config-3.13.0-27-generic:CONFIG_VGA_SWITCHEROO=y
/boot/config-3.13.0-29-generic:CONFIG_VGA_SWITCHEROO=y
/boot/config-3.13.0-30-generic:CONFIG_VGA_SWITCHEROO=y

:~$ sudo ls -l /sys/kernel/debug/vgaswitcheroo/switch
-rw-r--r-- 1 dule root 0 Jul 15 15:17 /sys/kernel/debug/vgaswitcheroo/switch

Now at "Using vga_switcheroo" section I didnt know what to do. I dont understand whats those echo commands for, anyway i tried all of them with root account in terminal and nothing happend. But this last "cat" command gave some output:

:~$ sudo cat /sys/kernel/debug/vgaswitcheroo/switch
[sudo] password for dule:
0:IGD:+:Pwr:0000:00:02.0
1:DIS: :DynOff:0000:01:00.0
:~$

So how I understood it says my Integrated graphic card is on and Im using it right now.

After that I replaced all killall -u "$USER" with gnome-session-save --logout in Roberto Martinez Switching script, saved it on desktop with name "switch_between_cards.sh" and made it executable.

Now on https://help.ubuntu.com/community/Hy...vga_switcheroo site it says i need to add some line in this file /etc/init.d/rc.local but on http://asusm51ta-with-linux.blogspot.com/ site I need to add it in this file: /etc/rc.local
In first file (/etc/init.d/rc/local) I dont have exit 0. It looks like this:

#! /bin/sh
### BEGIN INIT INFO
# Provides:          rc.local
# Required-Start:    $all
# Required-Stop:
# Default-Start:     2 3 4 5
# Default-Stop:
# Short-Description: Run /etc/rc.local if it exist
### END INIT INFO




PATH=/sbin:/usr/sbin:/bin:/usr/bin


. /lib/init/vars.sh
. /lib/lsb/init-functions


do_start() {
    if [ -x /etc/rc.local ]; then
            [ "$VERBOSE" != no ] && log_begin_msg "Running local boot scripts (/etc/rc.local)"
        /etc/rc.local
        ES=$?
        [ "$VERBOSE" != no ] && log_end_msg $ES
        return $ES
    fi
}


case "$1" in
    start)
    do_start
        ;;
    restart|reload|force-reload)
        echo "Error: argument '$1' not supported" >&2
        exit 3
        ;;
    stop)
        ;;
    *)
        echo "Usage: $0 start|stop" >&2
        exit 3
        ;;
esac

In second file (/etc/rc.local) i have echo 0, I added 2 lines before exit 0 and it looks like this:

#!/bin/sh -e#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
chown "dule" /sys/kernel/debug/vgaswitcheroo/switch # change "username" with your user name
echo OFF > /sys/kernel/debug/vgaswitcheroo/switch
exit 0

When i run script this window appears:
Screenshot from 2014-07-15 16:11:58.jpg

But when I click on switch to Integrated (or Discrete) that window dissapears and nothing happens. I think something is wrong with chown line in step before. Seems like I dont have root access for switcheroo or something (Im just guessing im noob).

How I saw some screenshots on that other site and in script window next to listed graphic cards it have (*)/( ) and Power On/Off which indicates if graphic is working or not (I think thats it) but I dont have it.

So do I need maybe to write only chown dule /sys/kernel/debug/vgaswitcheroo/switch line in /etc/init.d/rc/local and add next line exit 0 just before esac line? Or something else is needed?
