I was happily using Cinnamon until today, when Ubuntu suggested I update it. I do admit I didn't read what the update was about, and just let it run.
Problem is that now after a reboot, the Cinnamon session won't use the theme I was already using and it won't let me change to anything else than the standard theme, including Icons, GTK and window themes.
What bothers me is that if I log with a Gnome Fallback session or a Unity Session, I can change back to the theme I was using. As soon as I go back to Cinnamon though I'm stuck with the standard one. Trying to change the theme with Gnome Tweak Tool does absolutely nothing.
Also, I get an error message that informs that nemo has crashed with SIGABRT in raise ().
I tried removing (sudo apt-get --purge autoremove cinnamon) and reinstaling it, but nothing changed.
What can I do to go back to my old looks?
