Re: Inactive device under X

[observer <obs...@bl...>]

A few months ago I wrote a patch that allows the same functionality
using isolate device, the file is attached, its working very fine for
me, but before using the patch read it, Im a a very bad programmer,
and the patch is basically fine but it breaks the config options for
isolate device, you must use it like this:

Section "ServerLayout"
	Identifier     "Multihead layout"
	Screen      0  "Screen0" 0 0
	Screen	    1  "Screen1" RightOf "Screen0"
	InputDevice    "Mouse0" "CorePointer"
	InputDevice    "Keyboard0" "CoreKeyboard"
	Option	    "Xinerama" "on"
#	Option	    "Clone" "on"
#	Option	SingleCard
	Option "IsolateDevice" "PCI:1:0:0-PCI:1:5:0"
EndSection

Im not sure what options dont work any more at least you cant use
SingleCard any more you must use

	Option	"IsolateDevice" "PCI:0:2:0-PCI:0:2:0"

also im not sure if works with more than two devices

Maybe someone can fix it or take the idea, basically it just takes pci
ids as parameters and makes the xserver to =BFisolate? only those
devices.
