====== Linux Desktop Environment ======

Two desktop environments are available on the linux systems: KDE and GNOME. The default is KDE. To switch desktop environments you must be logged out and at the hellolinux login screen. Click **Options** and then **Select Session..**.

===== Changing screen resolution =====

==== KDE ====


If you want to change your screen resolution from the system default, you can use the **screen resize and rotate** utility, under the **system tools** KDE menu.

There is also a KDE tray tool that can be started by typing ''krandrtray'' in a xterm window.

==== GNOME ====

To change the screen resolution from the default, use the **Screen Resolution** tool under the **Preferences** GNOME Applications menu.

==== Command Line ====

From the command line, you can use the ''xrandr'' utility.

  * Get a list of available resolutions with the command "xrandr -q". This will give you a list of resolutions, each one has an index number with the default being 0.
  * Change your resolution using "xrandr -s n", where n is the index.
  * If for some reason you lose the display (eg the monitor won't sync), hit up arrow, delete, zero, enter (to set it back to index 0).
