Subject: Cinnamon 1.4: Failed to load session "cinnamon2d"

Date: Thu, 14 Aug 2014 09:48:33 -0400

Package: x2goserver
Version: 4.1.0.0-nightly

When I attempt to launch "session type" "custom desktop" "CINNAMON", I
get this error dialog:
Failed to load session "Cinnamon2d"
http://imgur.com/VQ0A1si

I emailed bug report 150 a bunch of details about Cinnamon 1.4 and my
test setup, but those details are not showing up on bug report 150. So
I am copying them (and made minor updates) below:

Clearly the problem is that x2goruncommand has incorrect logic for
launching this version of Cinnamon, 1.4.

Remember that this version of CInnamon, on this version of Linux
Mint, is supported through April 2017.

Version 1.4 is probably used on other distros too.

Can you provide a patch for x2goruncommand? Probably for x2goserver on  
release/4.0.1.x branch?

Yes, I plan to do so.

1st, I've been brainstorming what logic to implement for different
versions of Cinnamon. For example, do I run apt or yum commands to
check what version is installed? There are other packaging systems
too.

I think what is best is to run the 2D cinnamon session scripts in
order from newest to latest, if they exist. This will be a simple
script I can write quickly.

2.0 & 2.2: cinnamon-session-cinnamon2d
1.6 & 1.8: gnome-session-cinnamon2d
1.4: gnome-session-cinnamon

I determined the versions' commands by browsing the .deb contents under here:
http://packages.linuxmint.com/pool/main/c/cinnamon/

Do I still need to export DESKTOP_SESSION before calling the scripts?
Those scripts do not export it, but x2goruncommand exports it before
calling gnome-session.

Correction: in order from newest to oldest

   [ 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

 .
   [ 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 $HOME contains non-ASCII
       characters. (Fixes: #397).
     - Export XAUTHORITY env var in x2goruncommand to enable privilege upgrade
       for applications started via pkexec. (Fixes: #458).
     - x2gocleansessions: Don't print to stderr if the session state file cannot
       be found. This can happen during session startups. Report to system log
       instead.
     - Don't use Perl package File::ReadBackwards anymore.
     - Fix x2gormforward for 4.0.1.x release series (the X2Go::Log Perl module
       only exists in X2Go Server >= 4.1.0.0, the 4.0.1.x release series has to
       use x2gologlevel.pm in `x2gopath lib`. (Fixes: #617).
     - Pick x2gogetagentstate from 4.1.0.0 release series and adapt to usage
       with X2Go Server 4.0.1.x. (Fixes: #619).
   * debian/control, x2goserver.spec:
     + Update versioned D: x2goagent (>= 3.5.0.25). This assures that X2Go
       works with poly-instantiated /tmp directories.
     + Make sure x2gogetagentstate gets packaged in bin:package x2goserver.
     + Bump Standards: to 3.9.5. No changes needed.
     + Mark x2goserver-pyhoca bin:package as deprecated.
     + Drop D (x2goserver): libfile-readbackwards-perl.
   * x2goserver.spec:
     + Install {libdir}/x2go/x2gormforward into bin:package x2goserver.
     + Drop R (x2goserver): perl(File::ReadBackwards).
 .
   [ Oleksandr Shneyder ]
   * New upstream version (4.0.1.16):
     - x2gostartagent, x2golistsession, x2gosuspend-session and
       x2goresume-session getting agent state from ~/.x2go/C-$SID/state. This
       should help to avoid session damage. Remove nxcleanup. (Fixes: #302,
       #511).
     - Move session file to /tmp/.x2go-$USER. (Fixes: #523).
     - Fix x2gostartagent failures if kbd is not "auto". Remove comma at end of
       options file.
     - Set default value for clipboard to "both" in x2gostartagent and
       x2goresume-session.
     - Clean user SSHD process if connection between server and client lost.
       This should fix error "Global request tcpip-forward failed". (Fixes:
       #495, #547).
