Modesetting on ubuntu 21.10 with a geforce

I’m on this machine

$ uname -a
Linux me-Lenovo-Legion 5.13.0-22-generic #22-Ubuntu SMP Fri Nov 5 13:21:36 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

I have an external monitor connected through a thunderbolt → hdmi cable

The problem I have is that the dim control for the monitors isn’t working, the dim is always to the max

Also the color temperature control (in the Gnome Screens panel) doesn’t work

Both the monitors are as bright and as blue as possible :-/

This is the output form inxi

me@Lenovo-Legion:~$ inxi -G

It seems that the so called “modesetting” is not running

May it be that the monitors dim control and color temp control are not worink because of the lacking modesetting ?

I’m following this guide

How do I get my night mode and dim control to work ?

Thanks in advance

Night mode doesn’t yet work with the nvidia driver and a wayland session. You’d have to switch to an X11 session for this to work.
What do you mean with “dim control”? Brightness keys for the internal display?

as for the night mode, thank you

as for the dim control, yes, I mean the bightness

Not only the keys but also the crank in the Gnome GUI

Here’s a screenshot in which I have drawn an arrow to indicate the control I mean

Thank you

This didn’t work for me

Also, in the meantime I got an update to 495

and I lost the differentiated scaling on the 2 monitors. Sigh
