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.
Hmm, you say there are 4 external screens but the screenshot shows 6. Can you clarify how many physical screens are plugged in?

The 4 screens that are plugged into the Type C HUB are the following: * Dell Inc. DELL SE2419H * Invalid Vendor Codename - RTK * Dell Inc. SE2717H/HX K9V8V77201AB * Dell Inc. SE2717H/HX K9V8V7C40LRS Only 3 of them are working at a time.
So there are: - 4 physical screens - Only 3 are recognized by the system - The System Settings page shows 6 screens Are any of these screens the kind that are internally represented as two screens?

There are 4 screens that are plugged into the Type C HUB. The other screens are from other places such as HDMI, DP, etc. I'm specifically speaking about the ones that are plugged via my Type C HUB
Does it work in a Wayland session? You can switch by running `steamos-session-select plasma-wayland-persistent` in a terminal window. To make it return to the normal Steam-based UI by default, run `steamos-session-select gamescope` afterwards
