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.

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
