I just installed Ubuntu for the first time dual boot so I get to choose Ubuntu or windows. I then changed the setting where is doesn't ask for my password when booting up. I then installed Edubuntu desktop package. I then hit system and logged out that way i could be at the loggin screen that also lets you select the desktop environment. Edubuntu was not there but User defined session was so i clicked that thinking that might be Edubuntu and logged in. Now im totally stuck. Only walpaper on the screen as i realize now that is normal for user defined session but there is no log out button to change desktop environments now and since I set it to not ask for password at boot up there is no option to change it at start up. If i hit ctrl+alt+del it only lets you shutdown, restart, suspend, or hybernate.... no logg out. I have hit every key on the keybourd hoping something will pop up. I thought this must be a simple noob mistake that there must be endless artiles about this so did searches on google and forums and was shocked to find nothing about this. My next step unless someone can help is to uninstall and reinstall.
