I'd like to write a log when somebody attempt to access my computer. (e.g. enter login and password, doesn't matter successfully or not). I use Arch Linux and CDM (console display manager).

ps: I have very strong suspicions that someone really do it, and at least, I'd like to know what time it happen.

The log should already exist. Try using the last command.

Login failures are normally logged by syslog to somewhere like /var/log/messages You can grep that file for login failures.
