Enabling multiple user accounts for the Linpus distribution on my Acer Aspire One was not trivial. After booting, the user 'user' is logged on automatically, and this user was the only one which could use sound and the links to documents, music,... This is why I wrote a quick howto.
Before you start: Make sure you have a bootable usb-stick handy, in case your system refuses to boot after changing a file. I used Debian Lenny beta 2, with an updated kernel.
To display an xterm, press Alt+f2, and enter 'xterm'. You can enable the right-click menu launching 'xfce-setting-show' from the command line, and unchecking 'show desktop menu on right click' under desktop behaviour. (Click the left arrow on your task bar if it is hiding the 'Close' button of the settings dialog.)
Edit /etc/inittab: replace the line
#1:2345:respawn:/sbin/mingetty --autologin user tty1
(I commented out the lines for virtual consoles 2-6 as well, but ctrl+alt+fx seems disabled somehow.)
In '/etc/rc.d/rc.S', comment out the line
# /usr/bin/xinit -- -br>/dev/null 2>&1 &
That should do it.
