The installation finished without an issue. I checked the function of the Docking Station. Mouse, keyboard and network runs, but the display wan’t. I following the troubelshooting from the Arch Wiki, but nothing ist really helpful.

I was able to identify the following error, but i diden´t now, how i can solve it. I try it whit the evdi.git package from the AUR an have the same problem.

familie@familie-x280 ~]$ xrandr --listproviders

[familie@familie-x280 ~]$ sudo dmesg |grep displaylink
[familie@familie-x280 ~]$ sudo dmesg |grep evdi

[familie@familie-x280 ~]$ modprobe evdi
modprobe: FATAL: Module evdi not found in directory /lib/modules/6.9.10-1-MANJARO

I think that the missing evid modul is the cause, or iḿ on the wrong track?

You haven’t specified what docking station you are using, which is critical information. After all, if your docking station doesn’t require DisplayLink, then you would be going down the wrong path.

Hey,

i use a ThinkPad Hybrid USB-C Dock. Before i change to Manjore i use Linux Mint and there run’s whit display link.

Bye

OK, have you installed DKMS to build the evdi kernel module? That’s the only reason I can think of for evdi not being loaded; you’ll want to make sure the dkms package is installed.

However, that’s probably all I can suggest. DisplayLink is a pretty obscure technology which has never worked great (even on Windows), and it’s largely being replaced by USB-C Alt mode so I’m not sure how many people here will have encountered it. Good luck with it.

Hey,

In the last week, i repeat the installation of evdi whit the different package from the AUR:

  • evid
  • evdi-git
  • evdi-compat-git

All installation wasn’t successful on the first run, but after i connect the Laptop to the Docking Station (that’s was a accident) and reinstall the evdi-git package again, it’´s works. I was kicked out of the running system an need a login an it’s works

I’m not shure if this the solution, but for me it is. Hopefully for someone else too.

bye Robin
