Hi,<div><br></div><div>following up on the subject, I found out some more things:</div><div><br></div><div>quote:</div><div><span style="color:rgb(34,34,34);font-family:arial,sans-serif;font-size:13px;background-color:rgb(255,255,255)">I also noticed that it works for user Z, I can open a session.

I have enough space on the filesystem, I erased the .x2go directories in user Ys home folder. I can login over ssh with Y, so that is not a problem.</font></div>
<div><font color="#222222" face="arial, sans-serif">This problem by the way started happening after a I had a power failure on my server, so I wonder if something got corrupted. I reinstalled (purged) x2goserver, so the x2go install should be fine. </font></div>

<div><font color="#222222" face="arial, sans-serif"><br></font></div><div><font color="#222222" face="arial, sans-serif">So these xhost error messages are coming from the x2goserver and only for that one user (which is the strangest thing)</font></div>

The x2goserver does totally minimal logging and does not show what is wrong and why I cannot establish the connection. </font></div>

X seems to have a very weird idea of what security means and how it is instituted. (at where root is not allowed to access a users desktop without prior having given permission to it)</font></div>
<div><br></div><div>There must be something special about user Y, something that x2go saved in the home dir. What directories would I have to clean up to erase all cache / config files that x2go might store there when an external client connects to it?</div>
<div><br></div><div><font color="#222222" face="arial, sans-serif">Any pointers would be welcome. </font></div><div><font color="#222222" face="arial, sans-serif"><br></font></div><div><font color="#222222" face="arial, sans-serif">Thanks,</font></div>
