[XFree86] xdm question

[Pacho Baratta]

i'm building a customized kiosk for a project and i must solve a problem. i have 600 pc with 64 Mb ram, so i'm implementing very basilar desktop with fluxbox, and i need xdm at start to give the chance to choose the user in a very simple way. it works fine, but something i still need to fix. when i launch xdm, and then mozilla, i noticed very bad performance. the point is that when i do "ps -e" i see this output: .... ..... "xdm" "xdm" "xdm" "xdm" "xdm" "mozilla-bin" "mozilla-bin" "mozilla-bin" "mozilla-bin" "mozilla-bin" ..... ..... five instances of mozilla running means wasting about 50 Mb of ram, too much for my machines... so the question is: what should i change to stop all these instances of xdm/mozilla. i tought it's cause xdm and so mozilla get all 6 virtual screen so i changed /etc/inittab to stop all tty except tty1 and i got only 1 session of xdm running; but still 5 sessions of mozilla.. any suggestion? regards, pacho
