Doing Ctrl-Alt-T to terminate in the windows client will make the windows close but doesn't clean up the session on the server. Reconnecting still just connects you to a empty background screen.

Doing a logout on the MATE desktop locally works just fine.

I am testing on pretty freshly installed and updated server and on a new user where I first wiped out all settings by removing all dot files/directories

This is what is still running on the server as the user after trying to logout over X2Go

We have been using x2go fairly successful on CentOS6 machines now for a while. We are investigating upgrading to CentOS7 and I am now looking at the x2go situation

We get our x2go RPMS from EPEL

x2goagent-3.5.0.31-1.el7.x86_64 x2goclient-4.0.3.1-1.el7.x86_64 x2goserver-4.0.1.19-3.el7.x86_64 x2godesktopsharing-3.1.1.1-1.el7.x86_64

So far we have not discovered

1. doesn't work at all with GNOME desktop giving the "Oops" screen. Web search seems to imply this is a known issue with GNOME3 with no real solution though I am suprised this is not mentioned in the X2Go wiki FAQ. I hate GNOME3 anyway so can live without it for X2Go

2. works partially with the KDE desktop. There is the kscreen issue that is mentioned in the FAQ. Really unusable unless one does disable kscreen. Need to investigate further what consequences that has on normal logins.

3. installed MATE from EPEL. On first login it looks and works great but when you "Logout ..." to terminate the session it just hangs on a blank background. If you "suspend" the session via force closing the window and then try to reconnect it fails or just takes you right back to the blank background. One can force terminate the session with x2goterminate-session to clear it out and then get a clean login again, but I don't really want my users having to go though this.

So my question is really about the MATE issue which I would prefer to use. Anyone have any clues as to what might be going on or a fix?

I'm not sure if it's Mate or X2Go but when I first installed both X2Go 

and Mate on CentOS7 and tested, all was good.

Now it's broken for me also but somewhat differently.  When I logout it

just hangs with the background image that I used on my desktop. So I use control-alt-M to and then click on the white seal or whatever that animal is, and then when I get the start-up screen back, I select terminate to terminate the session.

Now I tried the same thing on Scientific Linux 7, which like Centos7 is

derived from Enterprise Linux 7, and it still works correctly, so whatever is broken isn't X2Go or Mate, but rather something specific to CentOS 7.
