Here is my problem it is Bug 765438--the backlight will not work on my Gateway NV 78 laptop. Won't work with Linux Mint 14, ubuntu from ubuntu 11.04 onward won't work with ps-bcd. Of course it works great with any Windows system, It works with the Ubuntu super OS but not Linux Mint. There is a fix. I just have to open /etc/rc.local and edit a command
Someone sent in this fix :
i915.broken=1 into command line
create a script under
#! /bin/sh echo "Fixing backlight for gateway NV78" setpci -s 00:02.0 F4.B=00 exit 0
Include that script path in
#!/bin/sh # fixGateway NV78 backlight PATH=/sbin:/usr/sbin:/bin:usr?bin if [ ! -x /etc/init.d/fix_backlight }: then exit 0
make the script executable:
sudo chmod 755 /etc/init.d/fix_backlight; sudo chmod 755 /etc/pm/sleep.d/fix_backlight;
acpi_osi=Linux to default grub start up script:
sudo gedit /etc/default/grub
acpi_osi=Linux after quite splash screen then
That's the fix, but I have no idea at all what to do to accomplish this. I really don't want to visit a Linux technician for this help. Any guidance where these files are will help.
I know where the /etc file is but can not open the /etc/rc/local file at all.
