Comment 2 for bug 1188387

Confirmed - this also affects me. Mint login manager constantly crashes, sometimes several times in a row. This has happened ever since installing Mint 15, right after the install and also after applying all updates. It seems completely random, sometimes I am able to get to login screen and log in, but most of the time it will just stick in a crash loop.

I am running the Nvidia proprietary display drivers on an AMD X2 5500.

I resolved the issue by installing KDM and setting that as default.

But really, this bug should at least be investigated, it can be a real showstopper for someone who does not know how to install another login manager and set that as default, or who does not know how to do that from the terminal where you will invariably end up if the login manager won't start.
