Subject: Desktop Sessions like KDE and ICEWM quit immediately after spawning with x2goserver >4.0.1.15

Date: Wed, 12 Nov 2014 13:46:41 +0100

Package: x2goserver
Version 4.0.1.18

Hi,

On OpenSUSE 13.1, starting a desktop sessions like KDE or ICEWM isn't
possible. After the window pops up on the client (Windows 7), it is
immediately  closed.
This applies to x2goserver 4.0.1.16, 4.0.1.17, and 4.0.1.18. Version
4.0.1.15 worked fine.

I don't see anything suspicious in the log files even in debug mode.
Starting a simple application, e.g. /usr/bin/firefox, also does work
with version >4.0.1.15.

best regards

Thomas

Do you have the package x2goserver-xsession installed?

I presume you obtained openSUSE packages from the OBS download  
location. Please note that we provide nightly builds (and soon release  
builds) for openSUSE, as well.
http://wiki.x2go.org/doku.php/wiki:development:nightly-builds#nightly_builds_for_opensuse_sles

This issue may be a packaging issue on OBS...

Greets,
Mike

Hi,

I was using the OBS version, as suggested by
http://wiki.x2go.org/doku.php/wiki:repositories:suse.
After the bug appeared, the main x2go repo was reverted to 4.0.1.15.
The OBS version does not have an x2goserver-xsessions package since the
files contained there are already included in the rpm for x2goserver.

I gave the nightly build a short try and it seems to work. However, now
I don't know if it's a packaging bug or a bug that has been fixed in
between version 4.0.1.18 and the nightly built version.

best regards

Thomas

in previous versions of X2Go Server, desktop sessions were executed  
like rootless applications if the Xsession mechanism failed in  
x2goserver-xsession.

This was changed for 4.0.1.16, however, now all desktop session  
startups fail for distributions we are not aware of.

For openSUSE (or SUSE in general, actually), this was fixed by a  
post-4.0.1.18 commit (present in the nightly builds and pending for  
release 4.0.1.19):
http://code.x2go.org/gitweb?p=x2goserver.git;a=commitdiff;h=3d98f8999f60840329241d82de6d741d1c2cbc9c

I will add a bug closure for this bug to the corresponding changelog entry.

Greets,
Mike

Hi,

In

you added a poll for /etc/SUSE-brand
However, on my openSUSE 13.1 systems /etc/SuSE-release exists and
/etc/SUSE-brand is not there.

best regards

Thomas

X2Go Component: src:x2goserver
Version: 4.0.1.19-0x2go1
Status: RELEASE
Date: Tue, 24 Feb 2015 21:49:22 +0100
Fixes: 405 632 633 638 644 664 668 671 672 675 676 678 697 698 700 712 715 727 728 770
Changes: 
 x2goserver (4.0.1.19-0x2go1) RELEASED; urgency=medium
 .
   [ Mike Gabriel ]
   * New upstream version (4.0.1.19):
     - Use File::Which to detect if sshfs command is available
       before trying to mount a client-side folder.
     - Be a bit more tolerant when trying to detect if a
       desktop icon is to be removed (using regexp, not
       eq).
     - Xsession script: Prevent bash failures when sourcing external bash
       scripts beyond our scope. (Fixes: #632, #675).
     - x2gogetapps: Support scanning of sub-directories when searching for
       .desktop files. We allow to dive down one level into subdirs, we on
       purpose do not recursively dive into the complete subtree. (Fixes: #633).
     - Make man2html an optional tool. Don't fail if it is missing on the
       build system (required for openSUSE/SLES builds).
     - Fix x2goserver-xsession/Makefile on SUSE. Detect SUSE distro and create
       Xsession related directory symlinks (xinitrc.d and Xclients.d).
     - Hack for x2goserver-xsession/Makefile during SUSE builds. If
       directoy /usr/share/doc/packages/brp-check-suse is present, the build env
       is also considered to be a SUSE system.
     - Trigger Xsession code for SUSE systems (look for /etc/SUSE-brand or
       /etc/SuSE-release for SUSE system recognition). (Fixes: #671).
     - x2gosqlitewrapper.c: Fix rpmlint error: no-return-in-nonvoid-function.
       Return the exitcode of execve().
     - Fix gramma in error message (in x2goresume-session).
     - x2gocleansessions: Call x2gormforward also on terminated sessions. This
       will make sure that re-assigned ports are really available on new session
       startup.
     - x2golistsessions(_root): Only update session state in session DB if
       x2goagent's state file really exists. This addresses a problem that occurs
       when x2golistsessions gets called via an x2gobroker-agent. The
       x2golistsessions script may show session states (--all-servers) of
       sessions on other servers that have session states files on their remote
       /tmp dirs. These files are not accessible for that x2golistsessions script
       and should simply be ignored. (Fixes: #638).
     - Provide pam_namespace support for has_agent_state_file() function.
     - Fix missing session list output if state file does not exist on the
       machine that runs x2golistsessions(_root).
     - Accept more verbose "DENY" output from x2godesktopsharing.
     - Make sure that all "su"-to-user-contexts use /bin/sh for wrapping around
       the executed command (in x2gocleansessions and x2golistsessions_root).
     - Also enforce /bin/sh as shell in su command in x2goprint.
     - README.i18n: Add file that explains the translation workflow for
       this package. Thanks to Mark Pedersen-Cook for drafting this file.
     - Make SSH agent forwarding work after having reconnected via SSH and
       having resumed a session. (Fixes: #672). Thanks to Robert Siemer for
       coming up with that idea.
     - Fix cross-user X2Go Desktop Sharing after being broken by implementing
       clipboard mode feature (and probably other code changes).
     - Document session startup / resumption failures (and their reasons) in
       server-side log output.
     - Handle AD domain users gracefully when X2Go is used with SQLite DB
       backend. (Fixes: #664).
     - Improve sanitizer, use 'x2gosid' sanitizer for session IDs everywhere.
       Drop unused 'pnixusername' sanitizer in 4.0.1.x release of X2Go Server.
     - Allow usernames in session IDs of length 48 chars.
     - Start sshfs with a timeout of 30 seconds (because it never finishes if
       something is wrong with the client-side TCP socket). Also remove/unmount
       mountpoints erroneously registered sshfs mountpoints if sshfs command
       times out. Furthermore, print errors to STDERR (not STDOUT). (Fixes:
       #405).
     - Handle execution of ss command from Perl script x2golistdesktops in a way
       that not only works on Debian, but also on Fedora et al. (Fixes: #727).
     - Provide legacy support for old File::Path packages in x2godbadmin.
       (Fixes: #715).
     - Fix wrong evocation of x2gosyslog ("error" -> "err").
     - Use "undef $dbh" instead of "$dbh->disconnect()". Fixes SQLite3 issues on
       SLE 11.x.
     - Only call $dbh->sqlite_busy_timeout() if the $dbh object is capable of
       that. Works around a too-old DBD::SQLite package on SLE 11.x.
     - Legacy for applications (and X2Go scripts) that expect $SSH_CLIENT to be
       set in the X2Go session's environment. (Fixes: #644).
     - Add man page for x2gogetapps. Weave into that a security / disclaimer
       message as proposed by Stefan Baur. (Fixes: #728).
   * debian/control:
     + Add D (x2goserver): libfile-which-perl.
     + Add C (x2goserver: x2godesktopsharing (<< 3.1.1.2-0~). (Fixes: #700).
