Ubuntu 16.04, D1000 Docking Station, displaylink-driver-1.1.62

Turning off secure boot in the BIOS solved the problem. I will probably try signing the driver later.

The first time the system came up after secure boot was turned off, I got the following error when I tried to configure the display settings.

Cannot open “Display” settings, error “Could not get screen information”

Doing the following --

sudo apt-get install --reinstall ubuntu-desktop

-- and then rebooting solved that problem.

Below is the output from lsusb. I believe I saw two DisplayLink drivers when I used the old driver with Ubuntu 15.10.

The sound settings are somewhat confused, but I doubt that problem has any connection with the display link driver.

After the multiple displays began working, I could not configure them because settings>hardware>displays responds with "could not get screen information".

I googled this problem and generally the suggestions involved invoking the following.

sudo apt-get install --reinstall ubuntu-desktop

This proposal may help accidentally, but after sorting out the various variants of gnome and experimenting, it seems that "settings>hardware>displays" is actually looking for appearance information, which has been removed from settings in the latest version of the gnome desktop configuration system.

If one clicks on the desktop background to get a menu including change desktop background and then clicks on change desktop background, appearance configuration pops up, and then one can choose "all settings" at which point displays works, and one can configure the multiple displays.
