Since the upgrade to Gnome 3.16, my /etc/X11/xorg.conf.d/20-intel.conf file is being ignored.
This file contains the following:
Section "Device"
Identifier "card0"
Driver "intel"
Option "Backlight" "intel_backlight"
BusID "PCI:0:2:0"
EndSection
It is necessary on my system to control brightness after sleep.
/usr/lib/gnome-settings-daemon/gsd-backlight-helper
is ignoring this configuration file. How do I configure gsd-backlight-helper to use the correct backlight device (/sys/class/backlight/intel_backlight) instead of the faulty one (/sys/class/backlight/toshiba)?
