[X2go-dev] trouble getting printing to work

[John A. Sullivan III]

Yes.  If you issue a mount command on the X2Go Server, do you see the
mounts for the sshfs shares, e.g.,

jas at jas:~$ mount
/dev/hdv1 on / type ufs (defaults)
none on /proc type proc (defaults)
none on /tmp type tmpfs (size=128m,mode=1777,noexec,nosuid,nodev)
none on /dev/pts type devpts (gid=5,mode=620)
jsull at 127.0.0.1:/home/jsull/.x2go/S-jas-54-1277203660_stDKDE_dp24/spool on /tmp/spool_jas/jas-54-1277203660_stDKDE_dp24 type fuse.sshfs (rw,nosuid,nodev,max_read=65536,user=jas)
jsull at 127.0.0.1:/home/jsull/ on /tmp/jas_media/_home_jsull_ type fuse.sshfs (rw,nosuid,nodev,max_read=65536,user=jas)

If not, you might be able to add debugging information to
the /usr/bin/x2gomount_sessions script.

If the mounts are there and it is still not working, you may be able to
add debugging information to the cups-x2go backend as it is simply a
perl script.  I'm not sure where that is -
perhaps /usr/lib/cups/backends.  Hope that helps - John
