distinguish between two deskhop on one computer

[chri2]

I have two desks I'm working on, each of the desks having its own deskhop.

Keyboard and mouse are different in both places and I'd like to setup my OS to use different settings for each of the keyboard/mouse on the different two deskhops.

The deskhop connected to my computer looks in both places the same - I can't distinguish between deskhop1 (keyboard a and mouse b) and deskhop2 (keyboard c and mouse d).

Therefore I can't e.g. (re-)map keys on the OS-side for each of the keyboards differently.

A possible solution would be to allow to setup a deskhop with a different from the default usb id or maybe allow setting of a serial number that on other devices can be recognized by e.g. udevd.

You may be able to track based on which USB port you are connected to,?

When you say two desks are both desks being run from the same computer?
