-A good friend of mine contacted me recently. He stated that he couldn't log in to his [Gentoo](https://en.wikipedia.org/wiki/Gentoo_Linux) installation. After a short talk on phone and various approaches I figured out that the problem must be on his LightDM manager so I adviced him to check his _/var/log/lightdm/_ log files. It was proven that the problem was caused by faulty installation of LightDM package files (wrong permissions) or authentication errors oin his [PAM policy](https://en.wikipedia.org/wiki/Privileged_identity_management). To conclude, all these errors can be very random and results of various reasons.
