"EDID Invalid" On Xubuntu 16.04

[OIKgnPdgNWHf]

Today when I booted the driver produced a SIGSEGV ("Cannot access memory at address") error without a monitor plugged into the adapter. So I tried a different monitor of the same model with the adapter and got the following EDID:

Raw EDID:
54 d4 7f 0b 2e 7f 00 00 00 01 00 00 2d 7f 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

The other monitor also produced a mostly null/zero EDID like the one above.

DisplayLink version is 1.1.68. I recall trying 1.0.335 first; not sure if that is a factor.
