Laptop display missing from settings and screen black

gr flag

So I had everything set up how I wanted, 2 Dell external monitors with my laptop screen turned off.

Come to my computer and the laptops display is on but black, and one of my Dell screen is off. I go to my display settings and i see this.

so I tried rebooting, no change.

I unplug the two external monitors and laptop screen is still black.

One of the external monitors i HDMI plugged into a HDMI to USB-c which goes into laptop, i just plugged it in straight with HDMI and then 2 displays return, i see this in the settings:

I'm pretty new to Linux and at a loss. I would at least like to be able to turn the laptop display off but it seems that Ubuntu is not recognizing my laptop display anywhere.

Also should mention that the same moniter-HDMI cable-HDMI to USB-c adapter connection is working fine on another windows laptop.

Sadly no, I really just feel like it was Nvidia sabotage. Went back to Windows, still want an answer though

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
