"If you believe that your desktop environment is overriding settings that you configured in nvidia-settings, some possible solutions are:
- Use the display configuration tools provided as part of the desktop environment (e.g. gnome-control-center display, gnome-display-properties, kcmshell4 display, unity-control-center display, xfce4-display-settings) to configure your displays, instead of the nvidia-settings control panel or the xrandr command line tool. Setting your desired configuration using the desktop environment’s tools should cause that configuration to be the one which is restored when the desktop environment overrides the existing configuration from nvidia-settings. If you are not sure which tools your desktop environment uses for display configuration, you may be able to discover them by navigating any available system menus for “Display” or “Monitor” control panels.
- For settings loaded from ~/.nvidia-settings-rc which have been overridden, run nvidia-settings --load-config-only as needed to reload the settings from ~/.nvidia-settings-rc.
- Disable any features your desktop environment may have for managing displays. (Note: this may disable other features, such as display configuration tools that are integrated into the desktop.)
- Use a different desktop environment which does not actively manage display configuration, or do not use any desktop environment at all…"
It’s very frustrating for me. The driver is good and efficient, but you can not permanently set of personal values of brightness, contrast and gamma.
It is there a chance to Gnome offered brightness and contrast controls integrated with gnome-tweak-tool or with any other tool?
