May be this works when having two video cards but when you only have one
you will have a great virtual desktop of 3046x1050. WM will use a
desktop size of 3046x1050 but you screen ony shows small part of the
desktop area at a resolution of 1366x768. ¿Am I right?

The virtual means that I get one resizable desktop, rather than two
separate desktops. Means I can drag windows from screen to screen
like Xinerama, but without Xinerama

I use WM 0.92 on mi IBM T23 (Debian Etch release), my dockstation
has a second PCI video adapter card.
In order to use both cards I configured manually my xorg.conf
file, as I do not use Xinerama at all I get two separate desktops
running WM when docked. If my T23 is not docked then I get only
one desktop/screen of WM.
The only strange thing I see is that you have in your xorg.conf
file the current line:
Virtual 3046 1050
This tells xorg.conf (not WM) to use a virtual screen of
3046x1050, when used whith only one screen the Virtual value must
match the real resolution value or should be omitted letting
xorg.conf to guess the values on the fly.

Asunto: Problems with multiple screens
Hi all,
Got a new laptop, and instead of using ximerama, I'm trying a
different technique of using multiple screens.
The problem with ximerama is that I didn't know how to change the
number of screens on the fly, so now i've switched...
Now I use my laptop with ATI graphics card, with xrandr. my
xorg.conf looks something like this:
Section "Monitor"
Identifier "aticonfig-Monitor[0]-0"
Option "VendorName" "ATI Proprietary Driver"
Option "ModelName" "Generic Autodetecting Monitor"
Option "DPMS" "true"
Option "PreferredMode" "1366x768"
EndSection
Section "Device"
Identifier "aticonfig-Device[0]-0"
Driver "fglrx"
BusID "PCI:1:0:0"
EndSection
Section "Screen"
Identifier "aticonfig-Screen[0]-0"
Device "aticonfig-Device[0]-0"
Monitor "aticonfig-Monitor[0]-0"
DefaultDepth 24
SubSection "Display"
Virtual 3046 1050
Depth 24
EndSubSection
EndSection
it was partially generated by aticonfig
If you allow it to define two devices, then you end up with an
independent wmaker on each monitor (dual-head), and only the mouse
can cross between the screens.
But if you define just one device and screen (as above), then
xrandr can combine the screens.
I set the virtual to be as large as the two monitors side-by-side.
When X first starts, its basically a crippled clone (the CRT's
resolution isn't ideal).
I open a terminal and run:
xrandr --output CRT1 --auto --right-of LVDS
That fixes up the CRT's resolution and puts it to the right of the
laptop.
What is great about this is I can then use xrandr to turn off the
CRT, or move it around, etc.
However, the problem is that wmaker is confused by this, and
believes the workspace is still the original size.
If I use the menu to restart wmaker, then it figures things out
correctly.
shouldn't wmaker be watching for randr changes?
cheers
Paul
