Hello, I've dual booted Ubuntu on my laptop starting with Maverick. Since Natty came out, I've had the backlight problem solved with
and then putting the line (minus 'sudo') into /etc/rc.local. Now, having done a fresh install from CD image of UbuntuStudio 12.04, this code works from a terminal, but not in /etc/rc.local.Code:
sudo setpci -s 02:00.0 F4.B=00
Thanks so much for help on this as well as the answers I've found in the past.
