At my work they have Displaylink USB port replicators. They do not work with the Librem 5 out of the box because Displaylink is a proprietary technology.
I discovered this the displaylink-debian project.
According to the project PureOS should be supported.
But when I do:
sudo -E ./displaylink-debian.sh --debug
Can't open display
See also this issue.
See also: Request - add support for PureOS.
The display-link Post Install Guide writes:
“When you are logging into your session you are using X server (X11) and not Wayland.”
So maybe the issue is Wayland related. But Displaylink should have Wayland support.
Did one of you get Displaylink working on their Librem 5? Or do you have any suggestions or tips to get it working?
