I recently did a sudo apt-get install kubuntu-desktop. Reboot loaded a kubuntu splash screen, then loaded the unity desktop. I read you needed kdm to handle the log in screen, so I did sudo apt-get install kdm. Reboot took me to a kdm login, but I can't do anything with the computer. Alt+f2 doesn't work, can't open a terminal, all I can do is move my mouse around.
Tried booting in recovery mode and doing sudo dpkg-reconfigure light-dm, but it says read only file system.
Ubuntu 14.04. It'd be nice if kubuntu worked, but I'd be happy with getting unity back at this point. Can anyone help?
