[Robert Kudyba]

Pardon the cross post from x2go dev list perhaps someone as seen this. Only
affecting 1 workstation.

On Fedora 32 with both MATE and XFCE, X2Go immediately quits with

Re: [X2Go-User] nxagent

[Robert Kudyba]

Why not just disable DPMS (Display Power Management Signaling) support?
https://github.com/ArcticaProject/nx-libs/issues/671#issuecomment-370715419

So a command like: /usr/bin/xset -dpms s off s noblank s 0 0 s noexpose
-dpms

[X2Go-User] debug logs for "This can be due to the local X server refusing access to the client"

[Robert Kudyba]

I’ve restarted DBUS, systemd-logind, x2goserver, and deleted the user .x2go 
directory, X2Go just goes black and disappears. Here are debug logs from a Mac. 
Anything informative here?

[X2Go-User] error getting session bus: Failed to connect to socket Connection refused

[Robert Kudyba]

I was able to get around the below errors by deleting the user’s .x2go 
directory. Any reason why this continues to happen? We’re using the nightly 
builds. Here are some logs. Fails with MATE and XFCE.

rpm -q x2goserver

 Unsable to determine failsafe session name.  Possible causes:
 xfconfd isn't running (D-Bus setup problem): environment variable
 $XDG_CONFIG_DIRS is set incorrectly (must include "etc'), or
 xfce4-session is installed incorrectly.

[X2Go-User] X2Go on Fedora 26 with NIS user fails with ICE I/O error on connection w. XFCE & MATE; something in .bashrc?

[Robert Kudyba]

>From the x2go log I see this:

So could something in the user's .bashrc which I'll paste here be causing
this?

Have you seen this page on how to enable debug logging? 
http://wiki.x2go.org/doku.php/wiki:development:debugging 

Other logging locations apart from the system's log are:

X2Go Server: /var/log/syslog
X2Go Client: stderr (use –debug)
PyHoca-GUI: stderr (use –libdebug –debug)
Xsession itself: $HOME/.xsession-x2go-errors
NX (server-side): $HOME/.x2go/C-/session.*
NX (client-side): $HOME/.x2go/S-/session.*
The default log levels for x2goserver and cups-x2go are set to notice. 
Available log levels are: emerg, crit, alert, err, warning, notice, info, debug.
The x2goserver log level can be set by editing:

root@x2goserver:~$ editor /etc/x2go/x2goserver.conf
Debugging X2Go Session Broker

The x2gobroker debug mode can be enabled in:

root@broker:~$ editor /etc/default/python-x2gobroker
The log files normally get written to /var/log/x2gobroker/*.log

You can also run

root@broker:~$ x2gobroker-daemon-debug
as user root. This is equivalent to running the broker daemon provided by the 
package x2gobroker-daemon, but you will see all output piped to stderr while 
the X2Go Session Broker daemon runs in foreground mode.___

What a mess there are a couple of moving targets:

1) https://bugzilla.redhat.com/show_bug.cgi?id=1417431 
 which requires enabling 
of the updates-testing repo.
2) This command ultimately worked: dnf --enablerepo updates-testing downgrade 
mesa-* --allowerasing

MATE is working again. Oye.___

What exactly does crash and when? The client? x2goagent on the server?


The X2Go client on his Mac desktop just goes black and kicks him out.

We have been working around it with XFCE and then using the work around for
DBUS when the same user is logged in via ssh and X2go.

[X2Go-User] X2Go crash from Mac/MATE to Fedora 25 w NIS user getting x2gostartagent: blocking creation of agent's keyboard file

[Robert Kudyba]

This only seems to be affecting one user. He has a NIS account and has
tried 2 NIS accounts to make sure. He's running a Mac with the latest X2Go
(2.7.11) connecting to a Fedora 25 server with NIS, choosing the MATE
desktop and audio disabled. We made sure to check the security settings as per
this older post screenshot

and
confirmed the .Xauthority permissions problem
 does
not exist. Here are some debug-enabled logs.

rpm -q perl-DBI

No this was an upgrade and has applications and users now that the school year 
has started. Seems the upgrade caused the issue. I got a hint from this thread: 
http://stackoverflow.com/questions/252/uninstall-all-perl-modules-installed-by-cpan
 


"If you can't use cpan any more because there are incompatible modules in you 
path, you can remove all installed modules by hand. For example, I upgraded 
from Fedora 22 to Fedora 23 and the Perl version changed. All modules installed 
previously via cpanm into /usr/local/lib64/perl5did not work any more and 
prevented me from using cpanm.

$ cpanm --uninstall Apache::
DBI

Attempt to reload Scalar/Util.pm aborted.
Compilation failed in require at /usr/share/perl5/vendor_perl/File/Temp.pm line 
18.
...
I could solve this by moving that directory:

$ mv /usr/local/lib64/perl5 /root/usr-local-lib64-perl5
The name of that directory may vary on your system.”

After I rebooted the Mac and installing XQuartz I was able to get in but just 
got this warning:

You have enabled Remote Printing or File Sharing. 
These features require a running and functioning SSH server on your computer. 
Printing and File Sharing will be disabled for this session. 

Please also check the Clientside SSH port in the general settings. 

The SSH server failed to start. 

X2Go Client did not detect a globally running SSH server on your machine and 
was unable to start its own. 

Please report a bug on: 
https://wiki.x2go.org/doku.php/wiki:bugs 


Disabling Remote Printing or File Sharing support in the session settings will 
get rid of this message.

[X2Go-User] Fedora 24 Connection failed. /usr/bin/perl: symbol lookup error: /usr/local/lib64/perl5/auto/DBI/DBI.so: undefined symbol: Perl_xs_apiversion_bootcheck

[Robert Kudyba]

Using the Windows and Mac clients we’re getting this error connecting to a 
Fedora 24 server. Seem like a problem with the perl installation. 

Connection failed. /usr/bin/perl: symbol lookup error: 
/usr/local/lib64/perl5/auto/DBI/DBI.so: undefined symbol: 
Perl_xs_apiversion_bootcheck 

perl -v

This is perl 5, version 22, subversion 2 (v5.22.2) built for 
x86_64-linux-thread-multi
(with 17 registered patches, see perl -V for more detail)

which perl
/usr/bin/perl

Seems like multiple installations. Any quick fix for this?___
