Linux Pluggable Authentication Modules (PAM) provide dynamic authorization for applications and services in a Linux system. Linux PAM is evolved from the Unix Pluggable Authentication Modules architecture.
Look at these files: /etc/hosts /etc/NetworkManager/NetworkManager.conf /etc/ncsd.conf
Linux can run with virtually any hardware configuration, but it is best to check the system requirements for your Linux distro.

Most Linux applications store files somewhere int he user's home directory, either in a folder of their own (such as .applicationname) or as a single configuration file. Deleting the configuration file should return the game to the default settings. Alternatively, you can try modifying the settings file and fixing the bad resolution manually.
System-wide configuration files are usually found in /etc. Personalized configuration files are stored in the user's home directory, in files and subdirectories preceded by a "." in their name.
Most Linux distributions come with several PAM authentication modules, including modules that support authentication to an LDAP directory and authentication using Kerberos. You can use these modules to authenticate to Active Directory, but there are some significant limitations.
One common problem that is faced by Linux system administrators is not understanding permissions. Not backing up critical configuration files and not choosing good root passwords are other problems new Linux system administrators may face.
I'm pretty sure that it's ifconfig...
