After running an update on Monday, on a Kubuntu 12.04 box, I've lost the option to select KDE in the login screen (there was a message that read approximately "option kde* has been removed"). Only "Default" and "Failsafe" remained. Using "Default" resulted in a black screen with only the KDE-style mouse cursor visible, using "Failsafe" brought me back to the login screen.

In the meantime, I've installed unity (and gdm along with it). I then attempted

sudo dpkg --reconfigure kdm

but that only brought back the KDE login screen (with additional GNOME/Unity session options). It looks like either some KDE package got uninstalled, or some configuration has been corrupted. Regarding the former:

I think some packages may be missing, but I'm not sure, and I don't want to experiment in fear of losing my KDE-specific configuration and/or making things worse.

In that vein: How can I restore the KDE option on login without losing my configuration?

Maybe some KDE package got removed?

Try sudo apt-get install kubuntu-desktop.

* facepalm *. Yes, turns out it was kubuntu-desktop and kde-workspace-bin . There really needs to be a more prominent warning that packages are deleted during an update... – mikołak Aug 8 '12 at 13:52
