I too had /dev/fb0 before plugging in the DisplayLink adapter.  In my 
case /dev/fb1 only showed up after plugging in the DisplayLink adapter 
so I used /dev/fb1 instead of /dev/fb0 (since plugging in the 
DisplayLink adapater created /dev/fb1 in the first place - this 
assumption may be wrong but worked for me).

I've also had to explicitly add "BusId" to the xorg.conf for the 
non-DisplayLink device.  You can obtain the BusId parameters via lspci 
(as root).  On my desktop machine I see something like:

01:00.0 VGA compaible controller: nVidia Corporation G92 [GeForce 98-- 
GTX+] (rev a2)

Then had to add something like:

Section "Device"

    # Add this next line to your existing non-DisplayLink device section
    BusId    "PCI:1:0:0" # this maps to the lspci output of 01:00.0 (as 
far as I'm aware - I'm no expert)
