DisplayLink not working on Dell D6000 Dock

Hi all, I’m having an issue where my Dell D6000 dock constantly loses communication with my monitor over HDMI Important to note that over DisplayPort my monitor is never detected at all. The losing connection issue sounds similar to the description here (https://github.com/displaylink-rpm/displaylink-rpm#dell-d6000 ) but the default.pa file does not exist on my system I have rebased to unstable to make sure I have DisplayLink installed. (bazzite-deck:unstable) So two questions: 1. How can I get this monitor to consistently work over HDMI (ideally at 60hz)? 2. Any additional fix to have the DisplayPort connection work? Thank you!

Just an update that disabling and stopping the DisplayLink service does allow my dock to work, albeit at the non-DisplayLink refresh rate of 30hz

Do you have any logs from the displaylink service we can look at? Might offer some hints as to what's going on here

Not seeing any DisplayLink logs in /var/logs - I did rebase to testing since I was experiencing a few issues on unstable Is there another place to look?

systemctl status DisplayLink

I think it’s no longer installed since I rebased to :testing Just says service could not be found

Might be all lower case

I think i've found a fix.

sudo systemctl restart displaylink.service
# Plug off the USB-C cable and wait other monitors being idle state
# Plug in the cable

@Kyle Gospo There is something going on with displaylink.service. When i startup OS, displaylink connected display works finely into login screen but after login it's blank black screen without signal. Fedora recognizes it and i can hover cursor inside monitor ● displaylink.service - DisplayLink Manager Service Loaded: loaded (/usr/lib/systemd/system/displaylink.service; enabled; preset: enabled) Drop-In: /usr/lib/systemd/system/service.d └─10-timeout-abort.conf Active: active (running) since Thu 2024-08-01 22:19:56 EEST; 19min ago Process: 7006 ExecStartPre=/sbin/modprobe evdi (code=exited, status=0/SUCCESS) Main PID: 7009 (DisplayLinkMana) Tasks: 14 (limit: 33376) Memory: 2.4M (peak: 3.8M) CPU: 449ms CGroup: /system.slice/displaylink.service └─7009 /usr/libexec/displaylink/DisplayLinkManager aug 01 22:19:56 bazzite systemd[1]: Starting displaylink.service - DisplayLink Manager Service... aug 01 22:19:56 bazzite systemd[1]: Started displaylink.service - DisplayLink Manager Service. Apparently, dock doesn't have enough power to push 120 or 144hz into both external monitors. I had to drop second monitor's refresh rate to 100 and it finally works. If both monitors are posting at login screen, they are both on 60hz. After login KDE settings cranks them both to user defined refresh rates and may cause these issues. Sometimes i can put both into 144hz, sometimes this happens...

there's definitely displaylink happening in here ayup

Just to clarify this issue, this is a bug in KDE. After switching to Bazzite-GNOME, both external monitors works great!
