Here's a procedure that worked for me in Ubuntu 18.04 Bionic.
For this procedure the user is "bob"
1) Install the latest brscan2 package (I have brscan2-0.2.5-1.amd64.deb

I just upgraded to from Xenial 16.04 to Bionic 18.04 and unfortunately

suspended the laptop with the same pattern of flicker it "normally" does
after resuming from a suspend.

IN case anyone is tracking this bug -- I wasn't able to use Unity in
