Hi there.
Has anyone encountered anything like this before?
Can't make displaylink-driver work on the recent Dell laptop. Got "evdi.0: [drm] Cannot find any crtc or sizes" errors.

* Did the standard displaylink-driver installation following
https://www.synaptics.com/products/displaylink-graphics/downloads/ubuntu
1. installed Synaptics APT Repository
2. apt-get update
3. apt-get install displaylink-driver
* Installation was smooth, no errors.
* systemctl status displaylink-driver shows it's running:

I believe this is a compatibility issue between the driver version and the kernel.
I've reinstalled the driver following

but got the same result.
PS: Did not have any such errors before on previous Dell models..
Has anyone encountered anything like this before?
