I use x11grab for this

https://ffmpeg.org/ffmpeg-all.html#x11grab

I don't think that you can select a specific window or desktop, but you
can select a region. I use a dual-monitor setup and record from the one
monitor and use the other for off-screen work.

I have also used a single monitor, with a split screen, to do the same
thing.

If you really need to work on a separate (virtual) desktop, then I guess
you could simulate this by running two separate X11 displays and
recording one of them.
