I have Linux Mint 14 64-bit Cinnamon on a desktop with an NVidia GTX 680 graphics card. I downloaded and installed the drivers from the NVIDIA website (installed on TTY1 with
sudo service mdm stop). The drivers work and the GPU is fully functional.
However, after running the update manager (because it's a fresh install), the Cinnamon environment becomes severely broken. The title bars are missing and so is the bottom panel. Alt-F2 doesn't work either.
I can get the title bars back with
sudo metacity --replace but the panels are still gone.
Setting session to "GNOME Classic" works fine but I much prefer Cinnamon.
How can I go about getting Cinnamon back?
