SOLVED Can't login to cinnamon anymore

[mrk]

I don't know exactly what caused the current behavior: i cannot boot into cinnamon anymore.

How to reproduce:
1. LMDE, (dist-upgrade performed), 64bit
2. Boot LMDE
3. Login to a cinnamon session
4. I then get a black, very reduced interface with no menu, no windows boarders etc.

After that I can open a terminal and start cinnamon manually - then every thing works as normal.

Ho do I get automatic startup of cinnamon back again?

Thank you for any hint on this subject.

This was so simple to fix I don't know why I had so long to get it:

Create a new entry using the autostart config tool (gnome-session-properties)

Name: Cinnamon
Command: cinnamon
Description: Autostart Cinnamon

Done.
