Unhappy AOC E1659Fwu not working with Ubuntu 16.04.01 LTS

Hello,

I just bought an AOC E1659Fwu 15.6" monitor and am trying to get it to work with Ubuntu 16.04.01 LTS.

I am using a Lenovo G580 with a 2.4GHz Intel Processor and 3GB RAM. I have a 64bit Ubuntu 16.04.01 LTS installed on it. The computer has two USB 3.0 ports.

I installed DisplayLink Driver displaylink-driver-1.2.65 (later I un-installed this version, restarted and installed displaylink-driver-1.0.335. No success.)

When I plug the monitor in , the AOC logo comes up and then the monitor goes black. I have tried using both USB dongles connected to 2 USB 3.0 ports.

Is there anything I can do to make this work?

Also when I try this monitor in WIndows 10, the extended desktop shows up, however the auto-pivot function doesn't work. So the monitor works except for Ubuntu or and doesn't do auto-pivot in WIndows 10.

Is there anything I can do to fix these problems?

Thanks in Advance

Thumbs down

I have the same monitor, exact same operating system (ubuntu 16.04.1)/displaylink driver, with a very similar issue. A frozen state of my main screen shows up on the monitor for 5 seconds, before the screen goes black again for another 5 seconds. This repeats around 10 times before the monitor goes black completely.

Very annoying after spending countless hours trying to debug this. Luckily I ordered on Amazon prime, and I'm likely going to return this and get my money back.

Would you be able to check if this still reproduces if you use a powered USB hub?
Issues like this might be caused by not enough power available from the USB port.

Cheers,
Michal

Default Tried with 2nd USB olugged into usb charger - no success

Hello,

I plugged in the AOC monitor into the USB 3.0, then the 2nd USB into a powered USB giving 5V at 2A.

The screen briefly flashes AOC - then goes to black.

Any suggestions? PLEASE HELP!

Thanks!

Hi,

I believe there are two issues here, stacked onto each other.

First is a problem with latest Linux release and 1366x768 resolution - mentioned here: http://displaylink.org/forum/showthread.php?t=65022 - you could try an earlier 1.1.x release, which should still work on 16.04 kernels (if not - compile the latest evdi sources from github manually, and use the rest of components from 1.1.x release as-is).
The other could still be, not enough power delivered.

I have tried this internally - took a build without the 1366x768 problem, and connected the screen through a powered hub with a short good quality cable and it works - see attached photo.

Regards,
Michal

Hi Michal,

I wanted to follow up this thread as I also have an HP ZBook 17 G3 thats running Ubuntu 16.04 with kernel 4.4.0-59 and an AOC E1659Fwu which has this same problem with driver 1.2.65 (using a built-in USB3 port directly).

As per your suggestion I've rolled back the driver to v1.1.62 and it seems to be working now.

However, in the background, there is a fair amount of evdi not being happy in the background. Not sure if you're bothered to debug this being an old driver but happy to assist in debugging from my end if you like as I'm a driver developer (although no experience of the displaylink modules directly) :

This looks like something we've already fixed.

Thanks for that ; should I be then using the older version of the released driver with a newer evdi module via github? Is there a formal process for installing both so they play nicely together?

Thanks.

We're releasing a version of the driver which will have this fix in, so please be patient. Expected this week!
