DisplayLink 5.4 and Linux Kernel 5.11 not working

[dmiller]

One additional note.

The sticky topic for Ubuntu 20.04 users (since Pop!_OS 20.04 is a derivative) suggests installing a 'fix' for xserver-xorg-core. This is marked as a fix for xserver-xorg-core (2:1.20.8-2ubuntu2).

I currently have xserver-xorg-core (2:1.20.9-2ubuntu1.2~20.04.2) installed and did not downgrade.

Thanks, dmiller.

Colleages, FYI, I tried The sticky topic for Ubuntu 20.04 users and downgraded my Xorg version to xorg-server 2:1.20.8-2ubuntu2. Upon downgrading my Xorg, i rebooted the system. It still does not work. Regards.

MT223,

Just wanted to follow-up for you. I've fixed my issue by removing the DisplayLink drivers completely from my system.

I have a DisplayPort 1.4/Intel 11th Gen/GTX 1650 Ti in my laptop. The Kensington SD4900P is a DisplayPort 1.3 device.

I've updated to use a Cable Matters DisplayPort 1.4 hub with MST and DSC support. This has allowed me to remove the DisplayLink drivers and have it 'just work' for 2 external 2560x1440 monitors.

Model number for reference is 201331-BLK.

Good luck!

dmiller, thanks for the suggestion. I purchased one of these devices and uninstalled the displaylink driver, too, and this is working well on my laptop with the latest linux kernel. I really appreciate the assist.
