I recently added an external monitor to my Debian 12 laptop, setting it as the primary display while using the laptop's monitor as secondary. However, I'm experiencing an issue where the external monitor randomly goes black, while the laptop screen continues to display normally. Moving the mouse brings the external monitor back to life. Interestingly, this happens while YouTube is running, with the audio playing uninterrupted. So far, I haven't noticed this behavior with any other applications.

Update: I was running YouTube from within the Firefox browser, not a YouTube app (If one even exists)

The issue seems to have been resolved?? It has stopped blanking except sometimes when I am logged out. I come back in the room to see it blanked, and then lights back up on its own. Stranger and Stranger.
