Fixed backlight but won't start after sleep

Asked by Jake Morgan

I am very new to all of this but I have a Gateway NV7802u laptop running Windows 64bit and Ununtu 12.10. After using the windows installer to install Ubuntu there was no backlight so I found a fix changing /etc/rc.local adding /usr/bin/setpci -s 00:02.0 F4.B=80. This fixed the problem but anytime it goes in sleep mode it seems to lose the setting and I have to open a terminal to run sudo /etc/rc.local. Does anyone know how I can work get this fixed.

Thank you!

You can add a script to /etc/pm/sleep.d/.
In this German guide, you can see an example with a different command: http://wiki.ubuntuusers.de/pm-utils#Eigene-Hooks-erstellen . Make sure the file is executable.

I'm sorry like I said I am very new to this and do not understand what you are talking about. I'm more of a step by step guy. I tried to play around with that but I don't know german lol.

Execute the command below to create the file

gksudo gedit /etc/pm/sleep.d/11_setpci

Inside the file write below script
____________________________________________________________________
#!/bin/sh
# Execute this command after resume-suspend to have the desired back-light result
case "${1}" in
    resume|thaw)

/usr/bin/setpci -s 00:02.0 F4.B=80

;;
esac
____________________________________________________________________

save the file and make it executable .. with the command below

sudo chmod +x /etc/pm/sleep.d/11_setpci

Now try again..

Thanks
