How to alter brightness, resolution parameters in Redhat Linux 9.0 with Gnome desktop
I am a new Linux user, redhat 9.0 and have been trying to figure out a few things with Gnome:
1. How to change the brightness and contrast features of the screen display?
2. The font of the toolbar and other menus of any window in Gnome is different from the font of the webpage or content displayed in the window. How can I change the font of the menus and toolbars and how can I set them so they are not reset automatically?
Thanks very much.
