### Please describe your issue in as much detail as possible:
I have a "Baseus Portal Joy Series 13-Port Type C Hub" with 4 screens plugged
into it. This is the exact one I have:
https://www.amazon.co.za/Baseus-Portal-13-Port-Type-Grey/dp/B0D45S6BLJ/
All 4 of the screens are shown in the System Settings:
https://github.com/user-attachments/assets/d560b365-d59a-4894-8515-6aae317aba63
>From the above screenshot, the 4 screens are:
* Dell Inc. DELL SE2419H
* Invalid Vendor Codename - RTK
* Dell Inc. SE2717H/HX K9V8V77201AB
* Dell Inc. SE2717H/HX K9V8V7C40LRS
It's the "Dell Inc. DELL SE2419H" one that is currently selected that keeps
disabling itself. I would enable it like so:
https://github.com/user-attachments/assets/09a92c5f-7889-4792-81dd-25775b2791f2
I press Apply, but then nothing happens. It shows it's enabled though, and when
I close System Settings and open it again, then the screen is disabled again.
So it seems like either it's not enabling it even though it shows it's enabled,
or it disables itself immediately after enabling it.
I don't know. Either way, I can't get the screen to be enabled and working.
