When you first open Linux Red Hat (with a Gnome Interface), probably the first you’ll notice is that it actually looks a lot like the Window interface.But although Linux looks a lot like Windows, it functions a lot differently. With Linux, you deal with an entirely different set of commands, and it behaves differently as well.
For example, in Windows you can adjust monitor properties with a few keystrokes. However, with Linux, you have to run a program called Xconfigurator to adjust the settings on your monitor. Basically, Xconfigurator helps you set up the configuration fields on your Red Hat computer.
Since there is no information on documentation on changing settings in Linux, you pretty much have to figure it out on your own. The problem is that you have to figure it out on your own. It’s one of the secrets of Linux that everyone seems to know how to do without having to look it up. If you’re switching from Windows to Linux, you’ll need to know a few Linux secrets to help make the transition easier.
Secret #1: Adjusting Your Monitor
In order to adjust your monitor in Linux, you have to be logged in as Root. You can then exit to the terminal. At this point, your screen should have a DOS prompt.
Follow the steps below:
1. At the # prompt type in the word, Xconfigurator.
2. A configuration program appears, asking you to provide the name, model number, and manufacturer of your monitor and video card. You’ll also need to supply the refresh rate.
3. You can usually find most of this information you need in your user manual or the manufacturer. Make sure that you have the information ready before you begin. From that point, all you need to do is fill out the form.
Secret #2: Exit the Terminal Before Running Any Programs
Always keep in mind that you must first exit the terminal before running programs without icons on your desktop. In Linux, Some programs will display an icon on the desktop once you install the program.
