Built-in display laptop is dark with last update Nvidia...

Last update nvidia drivers (propietary) with linux-hardened show built-in display dark... low brightness. Any idea? Thanks.

I assume that "Turn the brightness up" would not be a welcome answer here.   But. that is kind of where I am going.
Is the backlight completely off?  Or is it just really low?
Or, is the backlight all the way up and things are still dark?

Do you have multiple GPUs?  If so, is the correct one controlling the backlight brightness?

What desktop environment are you using? (console, Gnome, Plasma, Sway?)

Laptop with 2 GPUs, integrated and nvidia 3060. Gnome, but console same problem. Backlight is really low, not completely.
THanks!

Hello again... this problem solved edit: /sys/class/backlight/nvidia_0/brightness and set 100 value... but... How do I put this persistent value? When restarting the computer, both with external monitors and with the laptop monitor, the value returns to 10.
