I use jabberd clients, gaim, Gajim, etc... [by janux]
If I'm chatting w/ someone via GAIM, and the chat idles for a certain
amount of time, GAIM creates a new logfile when the chat resumes.
There are many instant messenger for Ubuntu and Linux system. This time I will guide you to install Gajim, a Jabber client application that is easy to use and install.
