Thank you for help and your gentle offer. Yet I would like to get x2go work out of the box. especially as our users own different platforms (linux, windows, mac).
After research on cups in ubuntu 14.04 I found out that I had to install the cups-bsd compatibility package. Now the error log changed:
excerpt from the syslog:
Jan 12 18:33:40 eaustria /usr/lib/cups/backend/cups-x2go[1874]: Call to printfile function with: /tmp/20-bmayr-cupsjob1874.pdf /tmp/20-bmayr-cupsjob1874.pdf.title eaustria.app.server bmayr-55-1421082562_stRPUBLISHED_dp24 Jan 12 18:33:40 eaustria /usr/lib/cups/backend/cups-x2go[1874]: x2goprint bmayr bmayr-55-1421082562_stRPUBLISHED_dp24 bmayr-55-1421082562_stRPUBLISHED_dp24_20-bmayr-cupsjob1874.pdf bmayr-55-1421082562_stRPUBLISHED_dp24_20-bmayr-cupsjob1874.pdf.title Jan 12 18:33:40 eaustria console-kit-daemon[2915]: GLib-CRITICAL: Source ID 1124 was not found when attempting to remove it Jan 12 18:33:40 eaustria /usr/bin/x2goprint.orig[1903]: ERROR: x2goprint was called with a wrong number of cmd line args, x2goprint exits now!
What should be the right number of arguments and how can I change them?
Thanks, Bernhard
