Hello,
I just started using Fedora 31 with KDE, with all the latest updates installed. It seems really nice, but I have a problem:
When I set the brightness for my three displays (DELL U2211H: DVI, DELL P2214H: DVI, DELL P2217H) in nvidia-settings it says “warning the color settings have been changed outside of nvidia-settings […]”. Everything is fine until the next reboot when the nvidia-settings forgets the set brightness values and I can start everything from the beginning.
How can I make this setting it permanent?
When I ran nvidia-settings I just saved nvidia-settings-rc but unfortunately, the set brightness values are not written into the file. I tried it with and without sudo but unfortunately, I just got the same results.
I have read the man pages of nvidia-settings (Yeah, its for Ubuntu, but the options are the same. https://manpages.ubuntu.com/manpages/precise/man1/alt-nvidia-current-updates-settings.1.html, I tried the
“3. Loading Settings Automatically”
part but when I ran nvidia-settings --load-config-only, nothing happened. (No error messages either)
Is there a way to tell the system to use the settings listed in the file?
I also tried -a option to assign values to my displays but it was a dead-end - for me at least - because I did not find the attribute name for brightness after a day of Googling.
P.S.: I use a GTX960 4GB and my proprietary driver version is 440.44.
Thanks,
Armand
