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 1) echo "Exit";; 101) gnome-screensaver-command -l;; 102) gnome-session-save --logout;; 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 fi I tested this HowTo on my laptop with Fedora 14 (x64) and Ubuntu 10.10 (x32). Please write me if you find any errors or have any sugestion to modify and improve this HowTo.
