ubuntu 14.04 desktop black screen on connect

Hi,
I install x2goserver on my new desktop Ubuntu 14.04 (gnome-shell) and I 
would like to connect it with another Ubuntu or Windows over my lan. I 
choose gnome as session and when I try to connect I obtain a black 
screen. Help me please!! :-)
Thanks

Firefox menu very slow

Hello,
I have a kubuntu server with x2go.
I reach this as full kubuntu desktop from a windows x2go client.
I have just installed client and server latest versions.

Unfortunately firefox (ONLY firefox) has this problem: when I click something 
that should open a menu the browser hangs for around a minute, then the menu 
appears and I can use it.

What can I do? 

Thanks in advance for any help,
Mario

Hello,

I am running x2goserver 4.0.1.15 with MATE desktop. When connecting to it with x2goclient 4.0.2.0 running on an ubuntu laptop, I get proper sound being transmitted to the client.

When firing up a thinclient, which seems to be running x2goclient 4.0.2.1, there is not sound being transmitted to the client.
I have run padevchooser on the server, which correctly shows pulseaudio as connected to a sink on my thinclient hardware. I've also checked the alsa sound mixer on the thinclient, to make sure nothing is muted, and I have run "speaker-test" on the thinclient, which produces noise (so speakers and all that are working).

Now I'm not sure what to do next? Is there any way (other than perhaps doing a network packet capture) to determine whether the server (running pulseaudio client) is properly streaming sound to the thinclient (running the pulseaudio server) in the scenario where I don't hear sound?

Any other ideas or troubleshooting methods are appreciated.

Thank you!

Jean

Re: Session suspending after resize

Hello,

Hello,

I am still trying to figure out why the automatic session resizing (when moving between clients with different screens, for example a desktop and a laptop) doesn't work anymore since I started using MATE.

Since the latest x2goclient upgrade, I noticed the following behavior: when I resume a session on a client with a different screen size, the screen will resize, but the session immediately suspends. Then when I login to the same session again (on the same client, so no screen resolution change), the session stays up.

When the session suspends, the log simply looks like this:

Session: Session resumed at 'Tue May  6 22:29:08 2014'.
Info: Screen [0] resized to geometry [1280x1024] fullscreen [1].
Session: Suspending session at 'Tue May  6 22:29:10 2014'.


And if I open the same session again (on the same screen), it just stays up although it reports the same resizing procedure being run:

Session: Session resumed at 'Tue May  6 22:31:38 2014'.
Info: Screen [0] resized to geometry [1280x1024] fullscreen [1].


Not sure if this is related, but if I press CTRL+ALT+R which is the command to switch between auto-resize and viewport mode, the session also immediately suspends, and the logs show this:

Info: Disabled desktop resize mode in agent.
Session: Suspending session at 'Tue May  6 22:35:46 2014'.
Info: Waiting the cleanup timeout to complete.
Session: Session suspended at 'Tue May  6 22:35:46 2014'.


Is there any additional debug information that I could see anywhere, to see what code is actually being executed when the session goes into resume?

Possible to use server SSH key like FreeNX?

Dear readers,

In FreeNX it is possble to change the default SSH key, so in addition
to have a valid username+passphrase to the host, the user also needs a
SSH key. The SSH key is the same for all users.

Is this also possible in x2go?

Kindest regards,
Jasmine =)

Gnome3, bug 42 seems to be fixed ???

Hello,

It looks-like that bug 42 has been fixed, and that Gnome3 works fine now
;-)   Great!

I am using Debian Wheezy as client and as server.

What I still miss is Desktopsharing in Gnome3. You can start it, but I
saw no way for the user to enable the desktopsharing in the normal mode
of Gnome (the user can enable it in the classic mode).

With regards,
Paul van der Vlis.

Problem compiling x2goclient

Greetings!
	I'm trying to work through an installation for IGEL again.  Apparently
I didn't take good notes the first time, so I'm trying to redo my
process (I've already found some things I may not have done the first
time, even though it was working).

Build platform: Ubuntu Workstation LTS 12.04.3, 32-bit (fully updated as
of 2014.05.14) *This is required per IGEL

I've done the following so far:

1) Download and unpack the source tarball for x2goclient-4.0.2.0.
2) Installed the following prerequisites:

build-essential qt4-designer qtcreator qtcreator-doc qt4-demos qt4-doc
qt4-dev-tools libqt4-dev git qt-sdk libldap2-dev libssh-dev libxpm-dev
libcups2-dev debhelper doxygen man2html-base

3) Run config_linux.sh (sudo /var/tmp/x2goclient-4.0.2.0/config_linux.sh
NOTE I received an error at this point:

make: *** No rule to make target `distclean'.  Stop.
Project MESSAGE: if you want to build x2goplugin you should export
X2GO_CLIENT_TARGET=plugin
Project MESSAGE: building x2goclient with ldap and cups
RCC: Error in 'resources.rcc': Cannot find file 'x2goclient_de.qm'
RCC: Error in 'resources.rcc': Cannot find file 'x2goclient_da.qm'
RCC: Error in 'resources.rcc': Cannot find file 'x2goclient_es.qm'
RCC: Error in 'resources.rcc': Cannot find file 'x2goclient_et.qm'
RCC: Error in 'resources.rcc': Cannot find file 'x2goclient_fi.qm'

RCC: Error in 'resources.rcc': Cannot find file 'x2goclient_nl.qm'

RCC: Error in 'resources.rcc': Cannot find file 'x2goclient_sv.qm'
RCC: Error in 'resources.rcc': Cannot find file 'x2goclient_zh_tw.qm'

I didn't think distclean was a big deal, this is a freshly build VM
running Ubuntu.

I'm not currently set up to run the x2gowebplugin so I ignored the
Project MESSAGE.

The RCC errors seem to be strictly relegated to Locale stuff, so I'm
ignoring them.

I proceed to trying to build x2goclient itself:
4) sudo make
Things go fine until an error on an ssh related object:

g++ -c -pipe -O2 -Wall -W -D_REENTRANT -DQT_WEBKIT -DCFGCLIENT
-D__linux__ -DQT_NO_DEBUG -DQT_SVG_LIB -DQT_GUI_LIB -DQT_NETWORK_LIB
-DQT_CORE_LIB -DQT_SHARED -I/usr/share/qt4/mkspecs/linux-g++ -I.
-I/usr/include/qt4/QtCore -I/usr/include/qt4/QtNetwork
-I/usr/include/qt4/QtGui -I/usr/include/qt4/QtSvg -I/usr/include/qt4 -I.
-I. -I. -o sshmasterconnection.o sshmasterconnection.cpp
sshmasterconnection.cpp: In member function ‘void
SshMasterConnection::checkReverseTunnelConnections()’:
sshmasterconnection.cpp:297:73: error: ‘ssh_channel_accept_forward’ was
not declared in this scope
sshmasterconnection.cpp:308:33: warning: comparison between signed and
unsigned integer expressions [-Wsign-compare]
make: *** [sshmasterconnection.o] Error 1

Note in the above prereq install, I installed the libssh-dev package,
but it looks to my uneducated eyes like I'm missing an ssh component for
this to build against...

Any ideas?

To preempt the suggestion to build a deb file, IGEL does not support the
installation of a deb package (dpkg doesn't exist on the firmware), so I
have to have a nearly standalone tree that I can install in a custom
partition on the firmware.  I have been able to write a script that
creates symlinks to some of the objects and libraries in this custom
partition, but the binary itself has to build and reside all in one file
tree.

Thanks for your help!!

x2go printer howto

client and server are both fedora 20.

I install cups-x2go on server (and x2goserver-printing).

I setup a cups-x2go printer on server on kde environment.

On the client I resumed session, with printing enabled (I did not try starting a 
new session).

On server, I can open kde printer settings and try printing a test page.  It 
seems successful.

Nothing is printed.

How to debug?
