Laptop, black screen after disconnecting from external monitor

[Xargon]

My laptop, a Dell XPS 9320 running Ubuntu 23.04 Lunar Lobster, is usually docked via usb-c hub, and connected to an external screen with the lid closed.
Whenever I open the lid it can recognize both internal and external screens but the internal one is black.
I tried to change some settings such as resolution, or enable/disable the internal screen but it stays black.
This even happens if I disconnect it from the hub: the internal monitor stays black while the computer is on.
I don't think it's a brightness problem as even with the mininum brigthness the screen is viewable.
When I say it's black I mean that it's (like it's) turned of.

When it's docked the primary screen is always the external one.

Please tell me if I can provide more information.

This bug never happened on LTS.
