v1.3.52 is not working with AOC e1649wu - Ubuntu 16.04

mlukaszek · 02-28-2017, 08:15 AM

Installation log look fine, but again, no signs of evdi but udl is loaded. As I suggested - do blacklist udl so it never attempts to open the device. Then reboot and connect the device - evdi should load and DLM should then start as well. What does `systemctl status dlm.service` show?

Cheers,
Michal

Sorry - ignore my previous comments; I just realized this monitor is indeed a DL-1xx device and is driven by udl - 100% open-source module that your kernel contains. You don't need evdi nor DisplayLinkManager.

Please clarify on

Code:

You don't need evdi nor DisplayLinkManager.

The monitor does not light up at all unless I install the Displaylink software. If evdi and DisplayLinkManager are not required, how do I get the monitor to work?

As I mentioned in my initial post, The older 1.1.68 release intermittently works with this display except that the USB display will not come back on after suspend or after unplugging the USB display unless I reboot.

Can you please clarify for me the proper way to blacklist udl in modprobe.conf so that I do it properly.
Also:

Code:

jr@jr-HP:~$ systemctl status dlm.service
● dlm.service - DisplayLink Manager Service
   Loaded: loaded (/lib/systemd/system/dlm.service; static; vendor preset: enabl
   Active: inactive (dead)

So I did the following:

1) Added

Code:

blacklist udl

to etc/modprobe.d/blacklist.conf and rebooted. No change
2) Added

Code:

blacklist udlfb

to etc/modprobe.d/blacklist.conf and rebooted. No change

3) Ran the DLSupportTool. Output attached as jr-HP_2017-03-01T16:08:13.071021.zip

4) Removed the two blacklist entries and rebooted.

5) Removed evdi

Code:

sudo dkms remove evdi/1.3.52 --all

and rebooted. No change.

6) Removed displaylink

Code:

sudo displaylink-installer uninstall

and rebooted. Monitor does not work.

7) Ran the DLSupportTool. Output attached as jr-HP_2017-03-01T16:28:51.725975_uninstalled.zip

Please advise. This device does not function properly with or without the latest Displaylink software on Ubuntu 16.04. It works with no problems whatsoever without drivers on a windows machine. It is operational using the 1.1.62/68 software as long as I don't unplug it or suspend the computer. (which is a big handicap) I am very frustrated and about ready to abandon my efforts and give it to my toddler to use as a snow sled.

Well, the device is definitely DL-1xx based device. These should be supported by udl driver - and if they don't work the source is there to poke around.

Since 1.2 driver for newer devices, we've changed the udev rules so they would only match DL-3xxx/5xxx-based products, not to interfere with udl kernel module that should be driving the older chips. This is also why DisplayLinkManager would not even start.

Bottom line is, DL-1xx devices working with the new Ubuntu driver is not something we support. I will PM you later with some hints you might try though.

Cheers,
Michal
