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

rup · 03-02-2017, 12:01 AM

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
