How to run second KDE being chrooted?

[jake5m]

Is it possible to start x and KDE from the chroot environment, but logged in as "knoppix" rather than "root" ?

Also, check to make sure the disk is not mounted nosuid or noexec, this caused me a whole HEAP of problems to debug.

sure ...

echo "exec $WINDOWMANAGER" >> /home/$USER/.xinitrc

echo "starting x11 for $USER"
su -c"exec /usr/bin/X11/startx" - $USER
