As promised, I am attaching 2 XF86Config-4 files.
The one called XF86Config-4-Wiedner is a modification of one I obtained from
Klaus Wiedner who posted it to the list last November and also on his T40
website: (http://www.w-m-p.com/linux-on-t40.html).
I got different behavior under Mandrake 9.2 (kernel 2.4.22, X4.3) and Mandrake
10.0 (kernel 2.6.3, X4.3), both with kde 3.2 (or 3.1). My internal LCD is
1024x768 and my external monitor is 1280x1024).
On MDK 9.2 I would get a single extended desktop with Xinerama enabled. (With
Xinerama disabled, I got a second ~/.kde/Desktop file the external monitor
had it's own configurable desktop. One can't move apps from one to the other
by dragging. When the external monitor isn't attached, that portion of the
desktop is generated by X but isn't visible because there is no monitor to
display it on...kind of a nuisance, but not a real problem. The window
manager's multiple virtual desktops are stacked one above the other, rather
than laid out left to right.
When I upgraded to MDK 10, this XF86Config wouldn't work. I would get the
same image on both monitors. The resolution was determined at boot time
based on whether the external monitor was attached. Because I stumbled upon
the next file which works better, I never investigated the problem.
The second file (XF86Config-4-Zamboni) is a modification of one that came from
Diego Zamboni and appeared in the November thread on dual heading.
On MDK 10.0, I get the same virtual desktop under Xinerama or two desktops
without. When I boot without the external monitor, I get a only the smaller
1024x768 desktop. The only catch to booting with the external monitor is
that I can't connect it (through a port replicator) until after the machine
goes through it's BIOS check (keeping it powerred off and then powering on
after BIOS doesn't seem to work here). Otherwise I get the same image on
both monitors. The resolution is 1024x768 if I take the default config. But
if I restart X after it autoloads, then both monitors display 1280x1024.
Despite this boot problem, I prefer the no external monitor flexibility
better than with the former file. If I attach an LCD projector (or other
external device) after X starts (in 1024x768 res), then the single image can
be shown on one or both displays by toggling FN+F7 as for Windows.
I never tested Zamboni's file under MDK 9.2.
In the November dual head thread, Wiedner describes a wonderful approach to
external monitors that I wasn't able to get working. Even on a single
machine it is possible to launch several iterations of X into the different
virtual terminals. Wiedner was able to harness this trick to launch a second
X iteration using VNC to display the second iteration on the external
monitor. Both monitors use his XF86Config-4 file, but each uses a different
iteration of X. It is a useful config, because it allows one to attach an
external monitor to an already booted machine and then display on the
external monitor, different content than appears on the internal one. Using
the standard FN+F7, you can only show the same content..
