X Configuration — Monitor and Customization

Configuring Your Monitor

The installation program will present you with a list of monitors to select from. From this list, you can either use the monitor that is automatically detected for you, or choose another monitor.

	Note
	If you are installing Red Hat Linux on a laptop with an LCD screen, you should select the most appropriate Generic model available.

If your monitor does not appear on the list, select the most appropriate Generic model available. If you select a Generic monitor, the installation program will suggest horizontal and vertical sync ranges. These values are generally available in the documentation which accompanies your monitor, or from your monitor's vendor or manufacturer; please check your documentation to make sure these values are set correctly.

	Caution
	Do not select a monitor similar to your monitor unless you are certain that the monitor you are selecting does not exceed the capabilities of your monitor. Doing so may overclock your monitor and damage or destroy it.

The horizontal and vertical ranges that the installation program suggests for the selected monitor are also displayed below the list of monitors.

If you decide that your monitor selection or the horizontal and vertical ranges are incorrect, you can click the Restore original values button to return to the original suggested settings.

Click Next when you have finished configuring your monitor.

Custom Configuration

Choose the correct color depth and resolution for your X configuration. Click Test Setting to try out this configuration. If you do not like what you see during the test, click No to choose another resolution.

	Note
	If you need to exit out of the X configuration test, use the [Ctrl]-[Alt]-[Backspace] key combination. Please note, this will not work in some test cases.

It is recommended that you test your configuration to make sure the resolution and color settings are usable.

You can also choose whether you want to boot your system into a graphical or text environment once the installation is complete. Unless you have special needs, booting into a graphical environment (similar to a Windows environment) is recommended. If you choose to boot into a text environment, you will be presented with a command prompt (similar to a DOS environment).

	Tip
	To change your X configuration after you have completed the installation, use the X Configuration Tool. Type the redhat-config-xfree86 command in a shell prompt to launch the X Configuration Tool. If you are not root, it will prompt you for the root password to continue.
