Bug#656: Fwd: Windows X2GoClient hangs when launching x2gostartagent

Package: X2GoClient
Version: 4.0.3.0

When launching a session from within the X2GoClient, the process will hang after the following call:

x2go-DEBUG-onmainwindow.cpp:3900> Executing remote command: "x2gostartagent 1440x900 adsl 16m-jpeg-9 unix-kde-depth_32 us pc105/us 1 D GNOME both"

This does not happen all the time, but generally happens after loss of network connection or after logging out instead of just closing the X2GoClient window. A complete restart of the client machine will solve the issue.

Bug#652: sound parameters from X2Go Session Broker ignored by X2Go Client

Package: x2goclient
Version: 4.0.3.0
X-Debbugs-Cc: Stephan Diehl <stephan.diehl <at> opensolutions.net>

Sound parameters obtained from an X2Go Session Broker get ignored by  
X2Go Client.

The question is, what sound parameters _should_ be controllable via  
the broker.

Proposal:

   o sound on/of -> configurable via broker (parameter:
     sound=true|false)
   o sound tunneling -> configurable via broker (parameter:
     soundtunnel=true|false)
   o sound protocol -> configurable via broker, overridable via
     cmdline option (parameter: soundsystem=arts|esd|pulse|none)
   o sound port ->  configurable via broker, overridable via
     cmdline option (parameters: defsndport, sndport)
   o start soundsystem -> not configurable via broker (should be
     false in most cases anyway, unless on Windows)

Bug#496: x2goclient crashes X session when switching from window to fullscreen

I tested also the x2go 4.0.3.0 with VcXsrv 1.16.1.0 x64 and  x32 and
the same crash occurs in Windows 7 SP1 x64 when switching from window
to fullscreen. The -logverbose 3 produced no extra info in

VCXSrv.0.log.

Subject: fixed in 4.0.3.0 via winmultiwindow.patch to VcXsrv
Date: 2014-10-23 22:50:27 GMT
Version: 4.0.3.0

TLDR: Fixed in X2Go Client for Windows 4.0.3.0 thanks to Alex's
winmultiwindow.patch to VcXsrv.

This was first fixed in VcXsrv 1.15.2.0-xp+vc2013+x2go1, thanks to the
inclusion of Alex's winmultiwindow.patch. X2Go Client for Windows
4.0.3.0-20141021 was released with VcXsrv 1.15.2.1-xp+vc2013+x2go1,
which inherits this fix. The "+x2go1" in the version string denotes
that winmultiwindow.patch is specific to X2Go's use of VcXsrv. It is
believed that the patch cannot be upstreamed, although I would love to
be proven wrong.

The source code for my builds of VcXsrv is available here:
https://sourceforge.net/u/mikedep333/vcxsrv/ci/xp-1.15.2.x-x2gochanges/tree/
This is the patch:
https://sourceforge.net/u/mikedep333/vcxsrv/ci/978ec71bbf4345f477fd4f937deb3a4b481862e2/
And the builds are available here:

Question about x2gocleansessions

Greetings X2Go Devs,

I use X2Go Server on ten Ubuntu linux machines and ran into an issue this morning upgrading them to 4.0.1.18.
We use an automated script I wrote which calls apt-get install and grabs its output, and it hung after
upgrading x2goserver.

After much digging, I found that it was hanging because stdin and stdout were not being closed by
x2gocleansessions, which is started during the postinst script for x2goserver. Looking through bug
reports and commits, it looks like there was a bug #441 to fix a similar problem, but this fix looks like it
wasn’t correct. Then, commit 336917af0dc087e4540fb3d55eb501d2fa4349be in 4.0.1.15 implemented a
more comprehensive fix, but specifically excludes closing stdin and stout. It looks this still includes
a lot of debugging code that should be stripped out, but I’m not sure.

My understanding is that x2gocleansessions should run as a daemon and therefore have no stdin or stdout or
at least redirect them to and from /dev/null, but I wanted to check to be sure I wasn’t missing something
obvious before I submitted this as a bug. I have briefly tested commenting out the two exclusion lines,
causing stdin and stdout to be closed, and it seems to work fine.

I’m not currently subscribed to x2go-dev, so please cc me directly on any response.

Thanks for all your excellent work on X2Go and I look forward to hearing back from someone.

Bug#496: log output

I've attached the x2goclient (4.0.3.0-20141021-debug) log and the
VcXsrv log of when this bug is triggered

The  X-Server command line options I am passing are shown in the .png. They are:
-multiwindow -notrayicon -clipboard -logverbose 3

-logverbose 3 does not do anything.

On IRC, user nkef posted a practically identical VcXsrv log:

Generous donation by IBM's Power Systems Linux department!


Hi list,

as you might have noticed a few months ago, IBM was interested in
getting X2Go running on the Power64 architecture.
I coordinated the efforts between Mihai (ionic) and Mike Gabriel
(Mike#1) and we managed to get things running.

While there is still a lot of work to do regarding fine-tuning, as a
thank you for getting them started with X2Go, IBM has provided quite a
lot of "swag" for us.

There are presents especially dedicated to Mihai, Mike#1 and me, but
also a whole bunch of other stuff dedicated to all the volunteers on
X2Go-Dev in general.

Pictures will come up soon.
I'm not done creating an inventory of things yet; as soon as I'm done,
I'll try to figure out a fair distribution.
Participants of "X2Go: The Gathering 2014" will be able to pick up
their presents there, for the rest, we'll have to figure something out
later.

-Stefan
