isI think xbacklight utility (xclient) should help here, so I would
also like know where to place the startup applications for gdm. Or
<val>' toit possible to do that with X server (xorg.conf) itself.
I am not sure about gdm, but I use xdm, and adding 'xbacklight -set
my login manager's Xsetup file did the trick.location and add
I have a xdm theme, so the location is /etc/X11/xdm/archlinux/Xsetup.
You just have to find out your login manager's X init scripts
all
that you want to Xsetup.
