Monitors not working

[krakerjak]

I am using Ubuntu 22.04 LTS and using Wayland, my external monitors are not displaying. When i go to Display Settings, my laptop display is the only monitor that shows up.

I have run lsusb -d 17e9:
Here are the results:

$ lsusb -d 17e9:

I have fun sudo systemctl status displaylink-driver.service

I have run the DisplayLink Linux Support Tool 5.2.1230 and have attached the zip/log file.

Both Monitors are connected to my Targus Dock 520 by HDMI cord.

Hello krakerjak,

Did you find any solution to your problem ? I'm facing the same issue.

I am using Ubuntu 22.04 LTS on a Asus Vivobook Pro 14 OLED N7400QE-KM032W with this docking station : ASUS USB3.0 HZ-3A Docking Station,

I have downloaded the 5.6.1 version of the driver and have followed this instructions. The only step that failed was

sudo apt-get install linux-signed-generic-lts-utopic

, the package couldn't be find. I also couldn't change the secure boot state as it was not prompted to me when I rebooted my computer, though I was able to enter the password in the "Enroll MOK" menus.

Hi!
Check the version of drivers. I used the most recent driver 5.6.1 (said to support Ubuntu 22) and had the same problem. Then I tried a legacy driver 5.5 (that worked before updating) and tadaa - my external monitors did work again. And I could once again set the same resolution on both monitors (that is also not possible in the latest driver if you even get it going). So uninstall and get a legacy driver (you get them under the latest driver on the home page).

Good luck and tell me if it worked out for you!
