Hallo Mike!
I would like to reopen the usb-printing-thing.

I have found the following line in the file /etc/cups/cups-x2goprinting.conf

printdsa = /root/.ssh/id_dsa-x2goprint

Yet in the folder /root/.ssh/ there is only one file: know_hosts  Should there be a key-file in it? Is this the reason, why printing on the local printer via a x2go virtual printer doesn't work?

Thanks, Bernhard

If the privs are different, the backend will run as user lp:lp, which will not work as x2goprint uses the su command and expects root privileges.
