Simplified displaylink (monitor attached to USB-C) procedure

Hello,

I successfully installed Arch on my HP-EliteBook including displaylink support

It seems the wiki is now outdated as requesting manual configuration I didn't have to do.

The only things I did

pacman -S linux-headers
yay -S displaylink
systemctl enable displaylink.service

and that's all.

And it will be even more simple if linux-headers were included as a dependency for evdi.

Can someone confirm on its own environment ? If so, I'll put a CR to for wiki update

Bye

Laurent

Install the displaylinkAUR driver. For Xorg it allows configuring DisplayLink monitors using xrandr in the same manner as the udl driver; for Wayland no configuration is necessary.

(emphasis by me)

Are you using wayland ?

Bad idea as evdi depends on dkms and dkms only requires headers for installed kernels.
(there are plenty of users that don't have linux kernel installed but use another repo kernel like linux-lts , linux-zen etc)

1.2.1 on the displaylink archiki page has (after configuring DKMS) .
having the correct headers installed is part of configuring dkms and mentioned on its archwiki page.

It does seem possible X autodetection no longer needs the conf files, please post the output of ls -lR /etc/X11 and xorg log .

I entered only the 3 lines in my top post, and never changed anything related to DKMS.
