    Question displaylink USB Monitor "Lenovo LT1421 wide" unuseable

    Hi,

    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/b...SUSE_Leap_42.3 )

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

    Thank you in advance!
    Eugen

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

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

    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 :-)

    Also enjoying OpenSuse unlikely to go back to Ubuntu
