I revived my new Dell server pre installed with Red Hat Enterprise Linux server v5.2. However, my box boot with a GUI login system ( Gnome ). There is no reason to run X Windows on my dedicated mail and Apache web server. I only need ssh. How do I disable X login and windows without reinstalling the operating system to improve security and performance?

Redhat Enterprise Linux (RHEL) install ImageMagick RPM for manipulating images

Q. How do I install ImageMagick software under Redhat enterprise Linux version 4 update 5?

A. ImageMagick is an image display and manipulation tool for the X Window System. ImageMagick can read and write JPEG, TIFF, PNM, GIF, and Photo CD image formats. It can resize, rotate, sharpen, color reduce, or add special effects to an image, and when finished you can either save the completed work in the original format or a different
one. ImageMagick also includes command line programs for creating animated or transparent .gifs, creating composite images, creating thumbnail images, and more.

ImageMagick is one of your choices if you need a program to manipulate and display images. If you want to develop your own applications which use ImageMagick code or APIs, you need to install ImageMagick-devel as well.

INSTALL ImageMagick

Use up2date command to install ImageMagick, enter ( <= RHEL 4 only): # up2date install ImageMagick
OR use yum if you are using Fedora Core/CentOS/RHEL 5:
# yum install ImageMagick
