External monitors not detected

English Hardware
1

I know there are a lot of post with similar questions, but none of them solves my problem…

I just switched from Ubuntu to Opensuse (Leap 15.6) on my Laptop and now none of my two external monitors are detected. They worked good with Ubuntu, so there are no hardware issues. I’ve tried the Fn-keys that switches to external monitor.

The laptop is an Aces Aspire3 with Intel i915 graphics. I have two AOC 24"-monitors connected to an HP port-replicator (one via HDMI and the other via Display port).

I am running gnome and tried to disable wayland/switch to X in /etc/gdm/custom.conf but it didn’t change anything.

What am I missing?

Here’s some output:

The inxi and Xorg.0.log output that you’ve shared just confirms that only the laptop display is active. What does lsusb report?

And here’s the output from dmesg:

I’ve tried disconnecting/connecting and turning the monitors off and on, but there’s no reaction.

Ok, so DisplayLink hardware. This will need the appropriate drivers to support it for video. I don’t have experience with DisplayLink on openSUSE. Let’s see what others suggest.

6

Yes, after some coffee I just realized that displaylink may be the problem. I will try to install it.

FWIW, here are a couple of blogs about openSUSE TW and DisplayLink…

You’re using Leap 15.6, but you the guides above might help with getting this mission accomplished. YMMV.

It was as easy as installing displaylink and it’s dependencies. Case closed.
