Hi,
I spent the complete morning trouble shooting displaylink and running out of ideas, now. So sorry if that post sounds a bit frustrated.
I have an i-tec USB 3.0 Docking Station with 2 HDMI outputs. The device works with Windows as expected. However on my SuSE Leap 15.2 (KDE) system screens stay black.
I know, there is only Ubuntu support however there are ready compiled packages for displaylink on the SuSE site. I installed them.
I made sure the displaylink service is running
Code:
sudo systemctl status displaylink
● displaylink.service - DisplayLink Manager Service
Loaded: loaded (/usr/lib/systemd/system/displaylink.service; disabled; vendor preset: disabled)
Active: active (running) since Sat 2021-04-17 13:13:23 CEST; 14min ago
Process: 6592 ExecStartPre=/sbin/modprobe evdi (code=exited, status=0/SUCCESS)
Main PID: 6596 (DisplayLinkMana)
Tasks: 30
CGroup: /system.slice/displaylink.service
└─6596 /usr/lib64/dl/DisplayLinkManager

Apr 17 13:13:23 CLIENT04 systemd[1]: Started DisplayLink Manager Service.
Driver seems to load, too:
Code:
lsmod | grep evdi

I had a look at all the logs, but couldn't find anything obvious failing. I tried to unplug/plug a HDMI cable - nothing happens in the journal logs. As if the system does not see the connected monitors at all.
The logs from displaylink are just binary junk not helping at all.
Anyone with a good idea on what to check next. How can I circle down the problem? Did I miss to find a good howto? Or is it just hacking the driver, pray that it might work else send back the device and forget about displaylink?
