Package: x2goserver
Version: 4.0.1.15

(Release: 0.0x2go1.1.git20140403.847.main.el6)

I am running x2goserver on Centos 6.x and x2goclient on the latest Ubuntu,
both completely up to date. Today I tried starting a connection from Ubuntu
while having the xinerama extension enabled. This fails with:

$ x2goclient
x2go-INFO-1> "Starting x2goclient..."
x2go-WARNING-1> "Can't load translator: :/x2goclient_nl_be"
x2go-WARNING-2> "Can't load translator: :/qt_nl_BE"
x2go-INFO-3> "Started  x2goclient."
x2go-INFO-8> "Starting connection to server: [redacted]:22"
X Error: BadDrawable (invalid Pixmap or Window parameter) 9
  Major opcode: 14 (X_GetGeometry)
  Resource id:  0x520001b
x2go-WARNING-7> "Error getting window geometry (window closed)?"

I disabled the xinerama extension and tried again. Now I can open the
session, but almost as soon as it opens, the session shuts down again. No
errors are reported. The only thing that appears client side is:

x2go-INFO-8> "Starting connection to server: [redacted]:22"

In the server log (attached) nothing appears, except a few warnings about
fonts not being found and that the session is being suspended. Strangely,
sometimes I can use the session long enough to move a few windows or type
something in, but it always quietly suspends.

The version of x2goclient is 4.0.1.1-1ubuntu2

I encountered the same problem, characterised by:

1. Warning about fonts in the log.

2. Session resumes briefly but then automatically suspends after about 1
second.

3. Log messages in ~/x2go/*/session.log as follows:

---
nxagentReconnectFailedFonts: WARNING! Font server tunneling not retrieved.
nxagentReconnect: WARNING! Unable to retrieve all the fonts currently in use. Mi
ssing fonts have been replaced.
nxagentSighupHandler: WARNING! Ignoring the signal in state [SESSION_GOING_UP].
keyboard file created
Session: Session resumed at 'Tue Jul 29 17:10:00 2014'.
Info: Screen [0] resized to geometry [1920x1200] fullscreen [0].
Session: Suspending session at 'Tue Jul 29 17:10:03 2014'.
Info: Waiting the cleanup timeout to complete.
Session: Session suspended at 'Tue Jul 29 17:10:03 2014'.
---

The cause of the problem was indeed that some fonts were missing on the
client (a gentoo system). I simply installed all the font packages I
could find one at a time until the problem went away.

In my opinion, the x2go client is not capable of running with missing
fonts, despite the message indicating that missing fonts will be
replaced. I think this may be a bug.

Tested with x2goserver version 4.0.1.15 and x2goclient version 4.0.2.0.

I think this is a duplicate of:
http://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=441

I'm a bit confused that you state that you are using x2goserver
version 4.0.1.15, which does not seem to be available for CentOS6.

Who can update the package there?

Best,
Reinhard

Can you enlarge on why you think #511 is a duplicated of #441? I don't  
see that right away.

The official X2Go package for CentOS6 come from the EPEL-6 project.

We provide unofficial RPM builds that are similar to the EPEL-6  
provided packages [1]. Maybe it got installed from there.

   [ Mike DePaulo ]
   * New upstream release (4.0.1.16):
     - Make X2Go Server aware of the Openbox desktop environment
       (Command: OPENBOX) (Fixes: #605)
     - Make X2Go Server aware of the IceWM desktop environment
       (Command: ICEWM) (Fixes: #606)
     - Support GNOME Flashback session (GNOME 3.8+) on distro releases such as
       Ubuntu 13.10+ and debian Jessie
       (NOTE: For most users, GNOME Flashback currently will not work.
        This requires that gnome-flashback.session actually be installed. Not
        every Linux distro has it available.
        It also requires that the gnome-session binary not require
        hardware 3D acceleration for said session. Currently, upstream GNOME
        and GNOME 3.8+ in all Linux distros do require this, only 3rd party
        builds do not. See X2Go bug #599 for example.)
       (Thanks Eugene San (eugenesan@gmail.com))
     - Fix launching GNOME 3 Fallback session (GNOME 3.4 & 3.6) on distros other
       than Ubuntu and Debian (Fixes: #599)
     - Fix support for Cinnamon 1.4 (Linux Mint 13) (Fixes: #569)
     - Fix the logic for launching Cinnamon 2.0 and 2.2 (Linux Mint 17).
       (Fixes: #572)
       NOTE: Fixing this bug in x2goserver is not sufficient to make Cinnamon 2.0
       & 2.2 to work properly with X2Go. Bug #150 in nx-libs is still a problem.
       Fixing this bug enables Cinnamon 2.0 and 2.2 to launch to their
       "fallback mode", which has many bugs and missing features when compared to
       "software rendering" mode (cinnamon2d), but is still better than nothing.
   * debian/rules:
     + Improve dh_auto_clean override.
 .
   [ Mike Gabriel ]
   * New upstream version (4.0.1.16):
     - Let x2goversion exit with an error if the X2Go component cannot be
       found.
     - Detect terminated sessions from NX log file. Also interpret a session as
       terminated if terminating just has started.
     - Detect started/starting/resumed/resuming sessions by explicitly scanning
       the NX session log file for those keywords.
     - Interpret NX sessions marked as "aborting session" as (not yet) terminated
       sessions.
     - Provide config option for server-side/global clipboard behaviour in
       x2goagent.options. (Fixes: #506).
     - Be aware of poly-instantiated /tmp directories bind-mounted under
       /tmp-inst. (Fixes: #406).
     - On suspend: Call x2goumount-session before sending SIGHUP to x2goagent.
     - Refuse client communcation if server-side hostname is not set up
       correctly (Fixes: #468).
     - Fix string comparison in x2goumount-session.
     - Fix problems with unmounting shared folders on session suspension/
       termination. Remove extra parentheses from the fusermount execution
       call. (Fixes: #407).
     - Use type -p instead of which in x2goumount-session. Suppress output
       to stdout properly.
     - Use if--then--else--fi during x2goagent resuming in x2goresume-session
       script.
     - More reliably sync the NX session state with the status information in
       the X2Go session DB.
     - x2golistdesktops: Also detect sharable desktop sessions behind abstract
       kernel namespace sockets.
     - Add logcheck rules for X2Go Server. Thanks to Frank Werner for sending
       them in.
     - Correctly use diversions from stderr to stdout in shell commands.
       (Fixes: #520).
     - Don't die if no session state file is found, as it will break X2Go
       completely after upgrading from versions << 4.0.1.16 if sessions
       are still running/suspended during package upgrade.
     - Provide support for client-side choice of clipboard security. (Fixes:
       #524).
     - Use more quotes in x2goruncommand.
     - Detect the exit of rootless applications that forked to background on
       application execution. (Fixes: #122).
     - Make x2goruncommand more robust.
     - Don't fail Xsession startup if any of the profile scripts returns
       with an error.
     - Silently timeout in x2golistdesktops if calls to x2golistsessions and/or
       xwininfo don't produce output within one second. (Fixes: #543).
     - Allow email addresses as login usernames. (Fixes: #573).
     - Abort session startup if env var $USER or $SSH_CLIENT are not set.
       (Fixes: #558).
     - Allow length of username up to 48 characters (was: 32 characters). (Fixes:
       #574).
     - Abort session if env var $HOME is not set or if $HOME contains non-ASCII
       characters. (Fixes: #397).
     - Export XAUTHORITY env var in x2goruncommand to enable privilege upgrade
       for applications started via pkexec. (Fixes: #458).
     - x2gocleansessions: Don't print to stderr if the session state file cannot
       be found. This can happen during session startups. Report to system log
       instead.
     - Don't use Perl package File::ReadBackwards anymore.
     - Fix x2gormforward for 4.0.1.x release series (the X2Go::Log Perl module
       only exists in X2Go Server >= 4.1.0.0, the 4.0.1.x release series has to
       use x2gologlevel.pm in `x2gopath lib`. (Fixes: #617).
     - Pick x2gogetagentstate from 4.1.0.0 release series and adapt to usage
       with X2Go Server 4.0.1.x. (Fixes: #619).
   * debian/control, x2goserver.spec:
     + Update versioned D: x2goagent (>= 3.5.0.25). This assures that X2Go
       works with poly-instantiated /tmp directories.
     + Make sure x2gogetagentstate gets packaged in bin:package x2goserver.
     + Bump Standards: to 3.9.5. No changes needed.
     + Mark x2goserver-pyhoca bin:package as deprecated.
     + Drop D (x2goserver): libfile-readbackwards-perl.
   * x2goserver.spec:
     + Install {libdir}/x2go/x2gormforward into bin:package x2goserver.
     + Drop R (x2goserver): perl(File::ReadBackwards).

     - Clean user SSHD process if connection between server and client lost.
       This should fix error "Global request tcpip-forward failed". (Fixes:
