Hi,
I want to decrease the refrash rate of the video to use less battery but
I am
having difficulties...
I have F35 with KDE on a Dell G15 with Nvidia GA107M [GeForce RTX 3050 Ti
Mobile], the RPMFusion drivers and a 1920x1080 resolution (native).
In the "system settings-display" There is the possibility to change
refresh from
120Hz to 60Hz but it doesn't stick; I change it and "apply" but if I change
screen and go back to "display" it's again at 120Hz, I tried
"nvidia-settings"
but it has only info, not settings.
The program "xrandr" reports
1920x1080 120.00*+ 59.97 59.96 59.93
Is this the problem 59.97 not 60?
Any suggestions?

Resending to list:
I think I may have seen something like this in the past, with the gui
reporting a possible refresh rate as an integer but not reinterpreting
that as the appropriate floating point value when trying to use it as a
setting.
Have you tried setting with xrandr?
xrandr --output <output> --rate 59.97
looks as if it might help, if I knew what to put as <output>
And the archlinux xrandr wiki looks as if it could be useful.
