Hi Everyone!
I just installed Fedora Silverblue 36 on my MSI Modern 15 - B5M.
Everything works fine, until I notice that my laptop (and 2nd screen) can’t turn off completely.
After locking the screen, the screen will turnoff, and then turned back on but only the backlight.
Does anyone know what might be happening?
I’m using Amd Ryzen 7 5700u with 16gb ram.

This is the video to demonstrate what I mean:

I have a similar MSI and I don’t think it’s specific to that. What fixed it for me was turning off notifications on the login screen. The notifications kept causing the screens to come on and off after locking it.

I don’t think this has something to do with notification.
Because I see no notification coming, and the only thing that keep turning on is the backlight. Not the entire screen.
