I was trying out Unity and then I uninstalled it but there is still an
Ubuntu Netbook Edition option in the GDM session list. Accidentally clicking on that causes the user to log in to a broken desktop. How can I remove it from the list?
After upgrading from Ubuntu 10.10 Lucid Lynx (10.10) Netbook Edition to Ubuntu 11.04 Natty Narwhal, the upgrade process does not remove the ubuntu-netbook and ubuntu-netbook-default-settings packages. Subsequent login attempts result in a broken desktop being displayed with background but no panels whatsoever.
In order to fix this problem, press CTRL+ALT+DEL and select the Restart option. When logging in after restart, after selecting a username, select Ubuntu session option from the drop-down box in the bottom bar. This will start the Natty's default session with Unity.
Next, run the following command in a Terminal window in order to remove the non-working option from the session list.
sudo apt-get remove ubuntu-netbook ubuntu-netbook-default-settings
