(!) [Kapil] Since Knoppix is based on Debian it is likely that it
uses the Xwrapper program. This is controlled by
/etc/X11/Xwrapper.config on a "sarge" version of Debian. This file
contains the "allowed_users" option with possible values of
"rootonly", "console" and "anybody".
(!) [Thomas] Kapil, you're not wrong, and indeed I actually use
Knoppix purely as a rescue CD, preferring my version of Debian
Sarge to be pure. Mind you, I might get around to running Knoppix
in a chroot jail at some point....
(!) [Kapil] For more details "man Xwrapper.config" is your best
bet. Since this file can be managed by "debconf" you could also
try to run
| dpkg-reconfigure -plow xserver-common |
