External USB-C monitor not detected

Support Graphics & Display

I have connected an asus zenscreen monitor to my laptop but it doesnt work. For the same laptop with windows it works, so the monitor is compatible with the computer.

I have seen that the installation of DisplayLink is recommended. And I have done the following steps: wiki. archlinux.org/title/DisplayLink.

/etc/X11/xorg.conf.d/20-evdi.conf is configured:

cat /etc/X11/xorg.conf.d/20-evdi.conf
Section "OutputClass"
        Identifier "DisplayLink"
        MatchDriver "evdi"
        Driver "modesetting"
        Option "AccelMethod" "none"
EndSection

and the service is running:

$ sudo systemctl status displaylink.service
● displaylink.service - DisplayLink Manager Service
     Loaded: loaded (/usr/lib/systemd/system/displaylink.service; enabled; vendor preset: disabled)
     Active: active (running) since Mon 2022-03-21 13:44:41 CET; 33min ago
    Process: 21185 ExecStartPre=/sbin/modprobe evdi (code=exited, status=0/SUCCESS)

However, I only get one provider:

$ xrandr --listproviders
Providers: number : 1
Provider 0: id: 0x44 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 3 outputs: 3 associated providers: 0 name:modesetting

Have you ever tried other external monitors? Did those work? Please also attach the output of

Yes, I have tried with other monitors but they were not portable and always with hdmi, so it works correctly.

$ inxi -Gazy
