[SOLVED]trying to set up external USB Asus MB169B: problem with evdi

Trying to set up Asus external USB monitor that shows on the usb bus as

$ lsusb
Bus 002 Device 003: ID 17e9:ff0b DisplayLink ASUSTEK MB169B+

I see by the wiki that displaylink is "experimental" but that there is hope of success with work.

So I'm trying to do the work following  https://wiki.archlinux.org/title/DisplayLink

I have installed evdi (more on this below) and displaylink from the AUR.

On starting displaylink service I see the following error.

:> systemctl status displaylink
* displaylink.service - DisplayLink Manager Service
     Loaded: loaded (/usr/lib/systemd/system/displaylink.service; disabled; vendor preset: disabled)
     Active: activating (auto-restart) (Result: exit-code) since Sun 2021-12-26 19:31:38 PST; 1s ago
    Process: 2684 ExecStartPre=/sbin/modprobe evdi (code=exited, status=1/FAILURE)
        CPU: 2ms

This is because the installation of evdi did not go well:

==> dkms install --no-depmod evdi/1.9.1 -k 5.15.11-arch2-1
Error! Bad return status for module build on kernel: 5.15.11-arch2-1 (x86_64)
Consult /var/lib/dkms/evdi/1.9.1/build/make.log for more information.
==> WARNING: `dkms install --no-depmod evdi/1.9.1 -k 5.15.11-arch2-1' exited 10
==> dkms install --no-depmod evdi/1.9.1 -k 5.10.88-2-lts
==> depmod 5.10.88-2-lts

I have configured for X using https://wiki.archlinux.org/title/Displa … xx_Devices

however

 xrandr --listproviders 

does not list  the monitor

The evdi build for the 5.15 kernel didn't work (which is afaik a known issue) the one for LTS did, did you try using the LTS kernel and can you reproduce the issues there?

It looks like that has been fixed in git, so you could try to build evdi-git from the AUR.

Yes. Using the  LTS kernel and rebuilding the AUR packages has fixed the problem.

Yes I tried that but the evdi build still failed. I'll try again in a day or so.
