(1) Mount "none" partition on fstab (just on Fedora, Ubuntu does it by default)
$ sudo gedit /etc/fstabAnd add the following line:
none /sys/kernel/debug debugfs defaults 0 0
(2) Change switch file permissions every time computer initiates
$ sudo gedit /etc/rc.d/rc.localAnd add the following lines:
chown "username" /sys/kernel/debug/vgaswitcheroo/switch # change "username" with your user name
echo OFF > /sys/kernel/debug/vgaswitcheroo/switch
$ sudo gedit /etc/rc.localAnd add the following lines:
chown "username" /sys/kernel/debug/vgaswitcheroo/switch # change "username" with your user name
echo OFF > /sys/kernel/debug/vgaswitcheroo/switch
(3) Reboot & copy and run script to switch between graphic cards
switch_between_cards.sh
#!/bin/bash
# "switch_between_cards.sh" script by RM, with useful changes from LoLL
# version 20101107

(4) OPTIONAL: Script to turn off laptop
This next script is used to turn off the computer. Because, in my case, if I turn off the computer without switching on both cards (specially when the integrated card is on and the discrete card is off), the fan runs at full speed when I turn it on again, stoping only after rebooting. Hence, to avoid this, this other launcher can be used to turn off the computer:
switch_before_shutdown.sh
#!/bin/bash
if [ "$DESKTOP_SESSION" = "openbox" ]
then
gxmessage "Are you sure you want to shut down your computer?" -center -title "Take action" -font "Sans bold 10" -default "Cancel" -buttons "_Cancel":1,"L_ock screen":101,"_Log out":102,"_Reboot":103,"_Shut down":104
case $? in
1)
echo "Exit";;
101)
xscreensaver-command -lock;;
102)
killall openbox;;
103)
echo ON > /sys/kernel/debug/vgaswitcheroo/switch;
gnome-terminal -e 'sudo shutdown -r now';;
104)
echo ON > /sys/kernel/debug/vgaswitcheroo/switch
gnome-terminal -e 'sudo shutdown -h now';;
esac
elif [ "$DESKTOP_SESSION" = "gnome" ]
then
gxmessage "Are you sure you want to shut down your computer?" -center -title "Take action" -font "Sans bold 10" -default "Cancel" -buttons "_Cancel":1,"L_ock screen":101,"_Log out":102,"_Reboot":103,"_Shut down":104
case $? in

echo "Exit";;

gnome-screensaver-command -l;;

gnome-session-save --logout;;
103)

gnome-terminal -e 'sudo shutdown -r now';;
104)
echo ON > /sys/kernel/debug/vgaswitcheroo/switch
