http://ubuntuforums.org – I had Kubutnu 12.04 which was shot after installing updates and could not fix the problem. So I installed Ubuntu 12.04 from CD and I did not like the desktop and tried Edubuntu which I did not like either. Then I decided to switch over to Kubuntu again and used this command to do that Quote: sudo apt-get install kde-full the install went through and after restarting, it showed Kubuntu log in screen, but after signing in, it went to Edubuntu desktop environment. Can some one help me to fix this problem. Thanks (Hardware)
