Hello,
I have been having intermittent problems with getting into x2go on RH6 machine. Recently, after update of x2go server and client, I am not having any success in connecting. I saw the same message before but I was able to connect after I tried multiple times (usually success rate about 10%).
The message is -

I usually see this when there are stuck session files. Make sure you don't have any processes running for that user. Clean out ~/.x2go. You may also have to delete some stuff in /tmp.

Try running 'sudo pkill -u user'. After making sure the folders are cleaned.
Also delete files in /var/lib/x2go/ But not the directory itself.

The logs from one of the previous mails show a crashing nxagent. Which is a bug. Please run gdb against the coredump in the mentioned abrt directory and post the output of gdb's bt command . We can then see where it crashes.

Did you have a look at the abrt-cli command? It stroes coredumps in some crash directory. So you might find some more.

Did you forget the "bt" call?
I don't see a debuginfo rpm for nxagent in http://packages.x2go.org/epel/6/main/x86_64/rpms/nx-libs/ but can you try to install http://packages.x2go.org/epel/6/main/x86_64/rpms/nx-libs/nx-libs-debuginfo-3..., restart gdb and issue the bt command, please?

Did you forget the "bt" call?
I don't see a debuginfo rpm for nxagent in http://packages.x2go.org/epel/6/main/x86_64/rpms/nx-libs/ but can you try to install http://packages.x2go.org/epel/6/main/x86_64/rpms/nx-libs/nx-libs-debuginfo-3... , restart gdb and issue the bt command, please?

Did you have a look at the abrt-cli command? It stroes coredumps in some crash directory. So you might find some more.

Alright, looks like we have a bug in the xkb code. Fortunately there is an upgrade to XKB 1.3 pending and will be merged soon (hopefully): https://github.com/ArcticaProject/nx-libs/pull/717
Regarding your current problem I would say: reinstall all x2go packages and retry.
Uli
Okay so after reinstall, I'm back to square 1.
But at least it helped identify a bug. Thanks for both of your help.
Unfortunately, I still need to get unstuck urgently ... deadline approaching. Do you know any other system like x2go that's free or low cost? I tried Xming but it's too slow to be useful. Thanks.

Alright, looks like we have a bug in the xkb code. Fortunately there is an upgrade to XKB 1.3 pending and will be merged soon (hopefully): https://github.com/ArcticaProject/nx-libs/pull/717
Regarding your current problem I would say: reinstall all x2go packages and retry.

You can try compiling nxagent yourself, it is not that difficult. Use that tree: https://github.com/uli42/nx-libs.git Branch pr/xkb_1.3.0.0
But what about RHEL7?
Uli
The crash happens ind XkbSendMap(). So I suspect some client in your session asking nxagent for the xkb keyboard configuration. You can look if you can disable that client. I suspect running a simple xterm via x2go will not crash the session. Can you confirm?

Unfortunately, the software I need to use do not support RHEL7 so we have to stick with RHEL6.
I tried opening terminal, but still have some problems. I assume "single application > terminal" is the way to do this.

You can try modifying /usr/bin/x2gosetkeyboard and see if it still crashes.

Uli,
That did it!!!! SOLVED! Thanks sooo much for your help.
After looking at x2gosetkeyboard script for a while, I realized that there was an option to manually set the keyboard in the preferences instead of relying on auto-detect.

I was only able to connect 10% of the time on a good day; now I can consistently connect every time. Note that this issue seems to only happen with Windows client. My colleague working on the Mac client never had this problem.
Thanks again!

Keyboard detection and setting on the Mac uses a different approach, as $SOMETHING on the Mac side of things is brain-dead and broken, so our usual approach for Windows and Linux doesn't work there.

Since xkb is something keyboard-related, maybe you could simply set X2GoClient to not touch the keyboard settings? No guarantee that this helps, but might be worth a try ... Go to the "Input/Output" tab in the session configuration, section "Keyboard", select "Do not configure keyboard". See if that helps. If you're on a macOS client, that won't be available, though. But I think your earlier screenshot came from Windows 10, so you might be in luck.

Check your /etc/hosts x2go doesn't like if this line is missing: 127.0.0.1 localhost

Alright, looks like we have a bug in the xkb code. Fortunately there is an upgrade to XKB 1.3 pending and will be merged soon (hopefully): https://github.com/ArcticaProject/nx-libs/pull/717
Regarding your current problem I would say: reinstall all x2go packages and retry.
