displaylink USB Monitor "Lenovo LT1421 wide" unuseable


this might be an odd problem for an “old” hardware:
I’d like to use an external USB monitor, which is correctly discovered but not usable:

I have no evdi kernal module found for 4.4.126-48-default (on my notebook and on https://build.opensuse.org/package/binaries/home:malcolmlewis:TESTING/evdi/openSUSE_Leap_42.3 )

Does anyone use displaylink?
Can anyone give me a hint to fix this?

Thank you in advance!

You need to use the update repo, no display link hardware here :frowning:

@malcolmlewis Thank you so much for creating this patch or whatever it is :slight_smile:

Been trying to get a USB Monitor to work Asus MB169+ with Asus ZenBook UX433FN for months now, after switching to OpenSuse Yesterday from Ubuntu distros, it now works like a charm. Again thanks Malcom :slight_smile:

Also enjoying OpenSuse unlikely to go back to Ubuntu
