This used to be a simple matter of proper xorg configuration. I
don't know if it still applies, but basically:
Add a second "Device" section for your new adapter. Let's say
the identifier is "USBadapter".
Add a second "Monitor" section for the attached monitor.
Identifier is "Monitor2".
Add a new "Screen" section:
Section "Screen"
Identifier "Second Screen"
Device "USBadapter"
SubSection "Display"
Depth 24
Virtual 1280 1024 # or whatever
EndSubSection
EndSection
and finally, modify your section "ServerLayout" to add this
line:
Screen "Second Screen" RightOf "Default Screen" # or
LeftOf, or Above or Below
Restart X, and it ought to be good.
You may need to increase your default Virtual to encompass both
screens.
