[arch-general] DPMS not working with fbdev driver

[Ralf Mardorf]

If needed, I switch between those drivers:

[rocketmouse at archlinux ~]$ grep Driver /etc/X11/xorg.conf
        ### Available Driver options are:-
        Driver      "radeon"
        #Driver	    "nvidia"
	#Driver	    "nv"
	#Driver     "nouveau"
        #Driver     "vesa"

Vesa is the last resort, only good to see something on the screen, if
anything else is broken. Apart from that I use different cards and
drivers depending on what does cause the less issues, regarding audio
real-time abilities.
