FVWM - Split Desktop into Multiple Virtual Desktops

Question

I have a Linux virtual machine running within VMware Fusion 3.

I have a dual monitor setup that runs thanks to the "vmware-user" application which enables both monitors as a single large display.

So, the physical layout of my monitors looks like so:

 ____________
|            |
|            |
|____________|
   ________
  |        |
  |        |
  |________|

And the VMware-tools application creates a large virtual screen that will contain the two physical screens.

 ____________         ____________ 
|            |       |            |
|            |       |            |
|____________|       |            |
   ________     ==>  |            |
  |        |         |            |
  |        |         |            |
  |________|         |____________|

I would like to somehow split my one large desktop into two "Virtual Desktops"...

 ____________         ____________         ____________
|            |       |            |       |            |
|            |       |            |       |            |
|____________|       |            |       |            |
   ________     ==>  |            |  ==>  |____________|
  |        |         |            |       |            |
  |        |         |            |       |            |
  |________|         |____________|       |____________|

My requirements are that I:

• Can still use FVWM instead of something else like KDE or GNOME
• Don't have to load an alternate video driver (I have no choice but to use the VMware video driver)

I have looked into some other articles where people mentioned using "fake xinerama" to achieve this, but I couldn't find any working links or documentation.

Thank you!

Answer 1

After reading more of the documentation, it seems that I am effectively attempting to split a single "screen" into two screens. While this might be possible with RandR and the "fakeXinerama" patch, it means I have to have two separate instances of FVWM open, and I will have to use the mouse to change the focus each time I want to use CTRL+ to change the current virtual desktop for the current "screen".

All-in-all, it would seem that I would have to develop this feature myself, at least how I see it so far. Thank you to those who took the time to look over this question.
