Hi Ralph,

...

4. Suspend the X2go session (describe us how you do that!!!)

From the pyhoca-gui I choose "active session --> suspend session.
("Sitzung anhalten" in German.) A message pops up saying "session suspended" followed by a second
message "session closed".

This looks odd... Could change the session command (LXDE, GNOME,
Single Application -> TERMINAL, Custom Command -> xterm, etc.). Does
the behaviour change when you test with different session commands?

What version of

x2goserver python-x2go pyhoca-gui

are you using (have you already mentioned that before in the
discussion? Please, check that again then)?

Greets, Mike

Ralph,

I believe I might be able to help with the admin rights issue, as I ran into it as well and did some digging.

There is an Ubuntu bug report here: https://bugs.launchpad.net/ubuntu/+source/policykit/+bug/221363

I think I ended up just replacing all instances of allow_active with allow_any in the policykit policy files, probably by running something like the following commands (make a backup first, though):

cd /usr/share/polkit-1/actions/
sudo sed -i 's/allow_active/allow_any//' ./*

Hi,

I have created a fresh Xen domu after all, based on Ubuntu Oneiric with the x2goserver from the Ubuntu PPA. And big surprise, it works: I can suspend and resume gnome sessions correctly. So I would say, Linux Mint is not a good choice to work with through x2go. But now I have another strange behaviour: I login via x2go / ssh to a gnome session, using my login name and a private sha key. Within this session I can execute root commands with sudo, but I cannot change any system preferences or modify users and groups within gnome. Obviously I'm lacking admin rights, although I am a member of the admin group. Might this have to do with LDAP or is the reason somewhere in x2go? Any hints?

Cheers,

Ralph

please do the following...

1. Become a watcher on the x2goserver (ssh -l<remote_user> <x2gserver>)...

2. Then start a session on that server as user <remote_user> (where <remote_user> is to be replaced by the username that you connect to the server with).

3. From the ssh session run ,,x2golistsessions'' (and if not promiscuous: send the output here).

4. Suspend the X2go session (describe us how you do that!!!)

5. From the ssh session run ,,x2golistsessions'' again (and if not promiscuous: send the output here).

Thanks, Mike

Ralph,

Sorry about that, I screwed up my instructions because I was doing it from memory. Here's the proper command (I put too many slashes in before), and you will also need to run it twice in a row because sed apparently only replaces one instance per line:

sudo sed -i 's/allow_active/allow_any/' /usr/share/polkit-1/actions/*.policy

Again, you will want to make a backup copy of the *.policy files (if you haven't already) before doing this. It should not be necessary to reboot, but you may need to close and re-open any applications you are having trouble with that are running at the time that you do the fix.

Also, the issue has unfortunately not been fixed (at least not in most cases) because it affects many different applications that plug into PolicyKit. I just did a grep and found many instances of "allow_active" instead of "allow_any" in the policy files.

Hi Ben,

sorry, but that doesn't do the trick. The sudo command does not work. I get the error message that 's/' is not understood. Also the bug report is quite old. That should be solved by now.

Thanks anyway,

Ralph
