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

The new version is not working. Support tool output is attached.
I uninstalled the old driver, rebooted, and installed the new version. Using a brand-new high quality USB cable and a powered USB hub. The AOC monitor shows alternating magenta/cyan bands. If I move the mouse across the screen it leaves traces of the pointer. Ubuntu 16.04 on an HP G72 laptop with an AOC e1649wu USB monitor as a secondary monitor. The older 1.1.68 driver release, works on this display except that the USB display will not come back on after suspend or after unplugging the USB display. Please advise. |
I don't see evdi or DisplayLinkManager running. I do see udl trying to access the device instead though - which is not right for this device (and you should probably blacklist udl in modprobe.conf). How did the installation end?
Cheers, Michal |
I had a problem with the e1659 not working on my HP laptop running 16.04 where the installation would fail, not building evdi and it wasn't immediately obvious. If you check evdi.ko, does it exist with a non-zero size?
$ ls -l /lib/modules/$(uname -r)/updates/dkms/evdi.ko |

I tried
Code:
ls -l /lib/modules/$(uname -r)/updates/dkms/evdi.ko Code:
sudo displaylink-installer uninstall after rebooting, I reinstalled with the following results: Code:
jr@jr-HP:~/Downloads/DisplayLink$ sudo ./displaylink-driver-1.3.52.run The new DLSupportTool output is attached. I read pev's post about editing the makefile. My evdi makefile is also attached if it helps. Thank you |
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. 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 |

So I did the following:
1) Added Code:
blacklist udl 2) Added Code:
blacklist udlfb 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 6) Removed displaylink Code:
sudo displaylink-installer uninstall 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 |
E1659Fwu Black Screen on host P50
Didn't read install instructions and plugged the E1659Fwu into my Lenovo Thinkpad P50.
Fix: CD is included with product, if you don't have a CD drive on your machine, find one that does and copy the CD files to USB drive. - Boot to Safe Mode - Control Panel - Display Adapter - Disable Nvidia Quadro - Boot to normal mode and install the drivers. Everything is working for me. |
