The log files are usually found in /var/log and you need to be root or use sudo to read them. They are text files so any editor (emacs, vim, kate, etc.) will be able to read them.

$dmesg will show you the lastest lines in /var/log/system.log (it's more or less "tail -30 /var/log/system.log"), even as a user.

I suggest you to read "man syslogd".
