If you’re an Ubuntu Linux user who just happened to install a full KDE desktop you may be wondering how to switch back and forth from GDM to KDM. The process is a simple as opening a console and typing a simple command.

After opening up a console type the command: sudo dpkg-reconfigure gdm and you will be prompted to enter your system password. This is the password you used when you installed Ubuntu. A screen will pop up asking you which display manager you want to use. Select, exit, reboot. Too easy!
