Almost fresh copy of Ubuntu 20.04 is laggy any time only monitors are connected through displaylink dock

br flag

If 1 or 2 monitors are connected only through the displaylink dock, the mouse moves slowly, but any action lags around a second. If I connect one monitor through the computers video card slots and one in the dock, everything behaves as expected. I'm trying to use this computer at my work workstation utilizing a USB switch to switch between my work computer running ubuntu and work laptop running windows.

On the problem computer Kernel: 5.8.0 X.Org X Server: 1.20.9 Displaylink: 5.4.0-55.153

Seems like it might be related to glxgears problem referenced at https://github.com/DisplayLink/evdi/issues/181 , for which there is a patch to X.Org X Server 1.20.8. Should I just downgrade that and try to apply the patch and keep Ubuntu from ever updating that?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
