New Displaylink driver is out now: https://support.displaylink.com/knowledgebase/articles/1944022-how-to-install-displaylink-software-on-ubuntu-20-0
However on my Thinkpad T480 and Lenovo USb3 Ultra Dock it is still not perfect, still I have 1sec lag. But I think, this is now displayLink driver related, not an ubuntu related issue, so this butg can be closed? . -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1875015 Title: Ubuntu 20.04 and Displaylink is extremely slow To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1875015/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
