[X2Go-User] Can't resume sessions on CentOS 7

[h i]

Hello,


We've had issues resuming suspended sessions. We connect to a linux server from 
different client machines (PC and Mac) using x2go. For some reason, after 
suspending sessions, we cannot resume sessions.


We receive messages such as:


X2Go-52
The remote proxy closed the connection while negotiating the session. This may 
be due to the wrong authentication credentials passed to the server.

The only way to resolve this problem is using the following two commands on the 
server:


rm -rf /tmp/.x2go-username/
 rm -rf ~/.x2go/C-username-*


After 2 attempts, we can log into the server using x2go, but a new session is 
started. The previous open session is terminated.


Is there a reason why this is happening? Is there an option to select during 
installation/configuration to prevent these resume problems?


Any help would greatly be appreciated.

Re: [X2Go-User] X2Go on Mac with MATE and NIS/Fedora 25 closes after opening

[Robert Dinse]

 It may be an issue with what shell they were using.  I know when I was
running MacOS (I've since loaded Ubuntu on my Mac) that it had problems if I
used any non-bourne derived shell such as tcsh.  But ksh, sh, bash, and dash
were all fine.

We made sure to downgrade mesa but this happens with certain NIS users. Non-NIS 
users do not have this problem. Here are some logs.
