DELL D3100 on Ubuntu 14.04.3

[abozvr]

Dear all,

I am trying to use the Docking Station Dell D3100 with a Dell XPS13 laptop with Ubuntu 14.04.3 running on it.

The Docking station is working well except for the "usual" monitor issue.

I installed the driver found here:

http://www.displaylink.com/downloads/ubuntu.php

I had no problem in running it; but then the monitor is not detected at all by the system :(

Any idea?

Thank you very much!!

Hi abozvr,

I don't know what hardware you use besides the docking station. I'm currently fighting with a D3100, a new XPS 15 and two U2415 monitors (all Dell).

I'm using the current driver on Arch linux. There is a nice description for the configuration here: https://wiki.archlinux.org/index.php/DisplayLink

I don't know how the DisplayLink service needs to be started in Ubuntu, but that is the first step after the installation.

For each additional provider you get, you have to set the provider output source. You may get a new provider for each monitor that you connect to the docking station:
xrandr --setprovideroutputsource 1 0
xrandr --setprovideroutputsource 2 0
#...
It's also necessary to load the udl kernel module as described.

You'll be able to work with the external monitors after that. (A restart may help in case of some issues)

Setting the provider output source is NOT permanent (at least on my system), so you may want to call this in a script every time after X is started.

I hope that helps a little bit :)

While I got my two monitors working with that, I have to mention that there are still issues. :( :confused:

the content of some open drop down boxes is not drawn
mouse trails stay partially visible sometimes
even more annoying: Some windows are shifted partially to the upper left, out of the visible area


It might have been more of an Xserver issue. Last time I updated my Arch linux, the two striked through marked issues have been gone :). The last seems to depend on some applications. For me, the mouse trails only keep happening with the opera browser. Its drop down boxes/pop-ups look still a little messed up as well. But all options are there and the boxes itself are in place.

Did you experience delay on your mouse movement?

I'm having a little lag, yes
