Ubuntu 16.04 no functionality

[ThaHypnotoad]

I'm plugging it in, seeing the monitor power on (this is one of the usb powered ones) and getting nothing. DisplayLink is showing up in lsusb, but nothing on the display itself, and nothing in the displays settings window.

edit: Everything worked for a year. This started happening when my original monitor stopped powering on and I had to rma it, but numerous things happened between when the original broke and when I got the replacement, so I can't narrow it down to any specific change in my system.

anybody at all? This is a linux specific issue, and it seems that if there's no support for this software, I might as well just return this crap.

So I'm running Ubuntu Xenial (16.04) (4.8.0-51-generic) and i'm having the same issue no matter what i do nothing appears, so let's start with lsusb:

lsusb -t -v (https://www.dropbox.com/s/zgjv5mujfninau4/usb1.txt?dl=0)
lsusb -v (https://www.dropbox.com/s/py59dm650pgz7am/usb2.txt?dl=0)

So nothing there to indicate an issue; now xrandr with displaylink DISCONNECTED:


chrisd@chrisd-ubuntu:~/Downloads$ xrandr

A quick look at my sytem in case it yields any info for you:

Any help or suggestions much appreciated!

Hi,

You're using NVIDIA proprietary driver. Does it work with nouveau?

Cheers,
Michal

Hi Michal, thanks for your prompt reply, so now it seems to kill my X session (well sort of my machine really) but if i ssh in from another computer first I've been allowed to run the logging thing. So please see new logs here:

Bump... Please is it possible to get an update on this

[R.E.L]

Hi,
after a long time I would today try my DisplayLink config again. It doesn't work because I was gone to Ubuntu 16.04. So I installed the newest DisplayLink software and still not working. lsusb shows the DisplayLink adapter, system setting not.

After some investigation I entered "systemctl start dlm" on a terminal and system setting shows the DisplayLink adapter/screen. Switching the DisplayLink display on and it ist working fine.

My DisplayLink adapter is 17e9:0141. May be it helps You too! For me is the question: "what to do to get my DisplayLink adapter running without typing the command each time I reboot?"

Regards Rainer

anybody at all? This is a linux specific issue, and it seems that if there's no support for this software, I might as well just return this crap.

My issue was using the Nvidia module in Xorg, once I switched back to the MESA module via bumblee / prime indicator and logged out and back in, viola the screens came up. I was amazed!

I am mainly writing this to anyone reading this, and to myself in the future. I recently upgraded from 14.04 to 16.04 and just kept using Nvidia because it was a bit faster until I got to work and plugged in my dock, thats when I had to debug this and figured this out.
