The pseudo-terminals (pts) allocated by xterm, rxvt and possibly others X terminal emulators are not registered in the utmp and wtmp files if the session of tty that called the X session is closed. Consequently the pts sessions not appears in the list of sessions of commands last(1), who(1), w(1) and others that depends of utmp and wtmp entries to run properly.
1) Make a login in the system tty console eg: ttyv0
2) Run the command: startx & exit
3) Open a xterm or rxvt using the window manager
4) Do commands last, who or w and verify that this session not appear in the list.
