Mouse clicks and keyboard response slow with primary display closed/turned off

[ashishbnv@gmail.com]

Hello Folks,

I ran into a strange issue that after installing the DisplayLink latest drivers, my mouse and keyboard is very slow if I close the my laptop display/turn of the built in display.

I upgraded to Focal from Ubuntu 18.04 LTS and it is not a fresh install. I previously had the Display Link installed and after the upgrade, I saw that my doc was not detected. That is when I installed the latest drivers.

As soon as I open my lid and the primary screen is activated, the performance is smooth again.

Dear friends,

I have been experiencing this issue for quite some time, since I run Arch Linux (rolling-release with always the most recent updates) therefore I run into these problems often and always very early.
I have identified this problem already over a month ago.
This seems to be a problem with the evdi-component that is installed with the displaylink driver (it's a dependency).

Someone has reported this upstream (with the Displaylink developers), since the displaylink driver depends on it.

PLEASE REACH OUT TO ME. I'M HAPPY TO COLLABORATE TO GET THIS FIXED WITH YOU.

Here's the link to the evdi-bug report:

By the way, see the links below.... I have reported similar behaviour in the past quite often:
