nvidia vs nouveau, xcfgmaker

В продолжение темы Create a boot option for easy nvidia or nouveau display driver switching

Делаем раз

# grep -1 depend /etc/init.d/xdm

depend() {
	need localmount xdm-setup

Отлично т.е. вместо /etc/init.d/xcfgmaker можно использовать /etc/init.d/xdm-setup
Этим и займемся.

cat /etc/init.d/xdm-setup 
#!/sbin/runscript

depend() {
	need localmount
}

start() {
	if get_bootparam "nox" ; then
		touch /etc/.noxdm
	fi
	if get_bootparam "nouveau.blacklist=true" ; then
		cp /etc/X11/video/20-nvidia.conf.nvidia /etc/X11/xorg.conf.d/20-nvidia.conf &>/dev/null &
		eselect opengl set nvidia &>/dev/null &
		eselect xvmc set nvidia &>/dev/null & # grep touch /usr/share/eselect/modules/xvmc.eselect
	fi
	if get_bootparam "nvidia.blacklist=true" ; then
		cp /etc/X11/video/20-nvidia.conf.nouveau /etc/X11/xorg.conf.d/20-nvidia.conf &>/dev/null &
		eselect opengl set xorg-x11 &>/dev/null &
		eselect xvmc set xorg-x11 &>/dev/null & # grep touch /usr/share/eselect/modules/xvmc.eselect
	fi
}

Как результат больше нет лишних велосипедов.
