How to switch desktops on Ubuntu

This is how I switched my desktop from Xubuntu to Ubuntu. Different combinations are done with a similar approach. See the reference below for a detailed explanation.

• sudo apt-get update
• sudo apt-get install ubuntu
• sudo update-alternatives --config usplash-artwork.so
  • Select artwork for the boot and shutdown screens, enter the following two commands in a Terminal window:
• sudo update-initramfs -u
• sudo dpkg-reconfigure gdm
  • However both Ubuntu & Xubuntu uses gdm, following step will resolve this problem
• sudo gdmsetup
  • If this fails to launch a GUI window, first run sudo su and then type gdmsetup
  • Go to “Local” tab and select the Ubuntu theme

When you logon next time do not forget to select the “gnome” as the current session.

In my case compiz caused Ubuntu to consume a lot of CPU power so I uninstalled it:

sudo apt-get –purge remove compiz* libcompizconfig*
