Extending Display with Kubuntu 22.04 and Docking Station

[pjhenry]

I installed Kubuntu 22.04 on my Dell Inspiron-3793 yesterday. All went fine, and there were no issues.

After the system updated, I connected the laptop to my docking station in order to extend the display, like I've done with my Win11 laptop. When plugged in, the Kubuntu laptop correctly finds the other peripherals plugged into the docking station; USB speakers, wired network, wired mouse, wired keyboard. It does not, however, find/recognize any of the external monitors that I would like to extend the display to; it only has the laptop screen as an option.

Doing a little initial reading, I've tried navigating to Activities, going to Display and seeing if there was any way of enabling or extending the display. I couldn't find any. I also tried navigating to the NVidia application to see if I could change any settings on the laptop for it to recognize the extended displays - couldn't find any there either.

System setup --

• Dell Inspiron-3793
• Acodot USB 3.0 docking station
• Hard-wired network cable into the back of the docking station
• Wired USB peripherals

Any advice would be greatly helpful! Thanks!

Are you actually using the Nvidia graphics, or the Intel?

Have you investigated if your specific dock actually supports Linux?

Can you provide any info on the specific model, so we can do some possible research on it?
The contents of the command lsusb with he dock connected should provide some useful info

if it is a DisplayLink device, you probably need to install some proprietary drivers:

https://support.displaylink.com/know...on-ubuntu-20-0 <<-- should still be valid for *buntu 22.04

Another install option, which also includes some useful information for after installing the drivers:

I cannot attest to how well this will work (assuming it is a DisplayLink device), or how good the drivers are, as I have no experience with it
