So in short, you'd have: * Two device sections * Two screen sections * Two ServerLayouts referencing your input devices, referencing the screens independently of each other. The main point is you must *not* use something like "leftof". Just one screen. Test your configuration like this: init 3 X -layout NameOfFirstLayout X -layout NameOfSecondLayout If the two layouts work, they should come up with classical "empty" X on one and the other head, now modify your /etc/X11/xdm/Xservers and change the line :0 local /usr/X11R6/bin/X :0 vt07 to :0 local /usr/X11R6/bin/X :0 vt07 -layout NameOfFirstLayout :1 local /usr/X11R6/bin/X :1 vt08 -layout NameOfSecondLayout When booting to runlevel 5, or whatever your "graphical login" runlevel (usually called display manager runlevel) is, the program started in the first place is xdm or one of its clones, kdm, gdm or wdm. xdm and kdm read the file /etc/X11/xdm/Xservers to find out what X-Servers to show a login screens. Those entries with "local" specify X-Servers that xdm / kdm will start locally to display login screens on. For gdm, I don't know, I think gdm uses its own Xservers-configuration from /etc/opt/gnome2/gdm/gdm.conf. Also be warned that the solution described allows you two use both heads switching, but you will only see one of the heads at a time. Also be warned that the two devices you configure must have different bus ids, otherwise XFree86 doesn't like it. So with two cards it works, with a Matrox G550 it doesn't work, with those nVidia or ATI GeForce or Radeon I don't know. When you want to see both heads at the same time, but use them as different displays, afaik you will have to connect a second mouse, second keyboard, patch your X-Server to not use / block a Linux VT and use the new Kbd instead of the old Keyboard driver. Last warning: Any information without warranty, your hw may suffer ;-) I hope this helps. - -- ITCQIS GmbH Christian Wolfgang Hujer E-Mail: Christian.Hujer@xxxxxxxxxx WWW: http://www.itcqis.com/ -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.2-rc1-SuSE (GNU/Linux) iD8DBQFAllBtMgwgpCF2K9sRAuqqAJ4o7RS0yafjaJ3x6RCVldW7fkfiuQCgjpyO W98+mj12bd55GZQWOiXHnI0= =Plqs -----END PGP SIGNATURE----- _______________________________________________ XFree86 mailing list XFree86@xxxxxxxxxxx http://XFree86.Org/mailman/listinfo/xfree86
