simple-scan does not work over x2go-remote-desktop session.
See there: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=761398
It is most probably a problem with user-rights and and with the sane-backend.
When trying to scan, it looks like this on the terminal:
andreas at md-ho:~$ simple-scan
p11-kit: invalid config filename, will be ignored in the
future: /etc/pkcs11/modules/gnome-keyring-module
** (simple-scan:23088): WARNING **: scanner.vala:801: Unable to get open device: Access
to resource has been denied
xsane says: 'Failed to open device 'pixma:04A9172B': Access to resource has been dnied.
But scanning works, when there is a local session running on the machine (i.e. the
remote-desktop server) from the same user.
Normally this is no problem at all for thin-clients, because they do not have a scanner
connected to the desktop-server. But in my case it is a problem. I also do acknowledge
that not many people do have this problem, so it is severity 3 only.
Please let me know, if I should rather report this against the sane-backend.
There is the original report:
