My current test environment is 32 bit Windows XP. We have another user testing 64 bit Windows 7. Most of the complaining users are 32 bit Windows XP. The disappearing mouse pointer is an Xming bug. Moving to vcxsrv will solve that. I think 3.0.1.14 was the first to support that but I'm not sure. We are also using an old X2Go Server - 3.0.1-5 I believe. Thanks - John

DRI role in x2go
by Shanon Loughton 20 Jul '11

20 Jul '11

Hi Im trying to understand how DRI works with a linux server display device and x2go. Id like to get opengl rendering completely in software on an Ubuntu server and so far so good - ive installed libgl1-mesa-swx11 which in Ubuntu auto removes libgl1-mesa-glx, and 'glxgears' and 'glmark' run nicely through x2go, considering the HW limitations. For some more complicated applications inc wine im running into openGL errors and im curious if any part of the server's X is still trying to direct render anything? I read somewhere that in the xorg.conf I can locate the device and set "NoAccel" to true which disables DRI and forces ARB shaders or something. Would this be worthwhile? thanks Shanon

How does one > build this x2goclient from source? Thanks - John You have downloaded the last release without Makefile. The next release (and also the code in X2go Git) contains a Makefile that you can use with make && make install so that x2goclient gets installed to /usr/local/bin. Two options: (a) wait for Wednesday/Thursday, then I will patch code from Alex into the current Git code and after that x2goclient will be releases as 3.0.99.0 (as tarball). (b) clone the current Git code: $ git clone git://code.x2go.org/x2goclient.git and then do $ cd x2goclient $ make && make install Greets, Mike -- DAS-NETZWERKTEAM mike gabriel, dorfstr. 27, 24245 barmissen fon: +49 (4302) 281418, fax: +49 (4302) 281419 GnuPG Key ID 0xB588399B mail: mike.gabriel(a)das-netzwerkteam.de, http://das-netzwerkteam.de freeBusy: https://mail.das-netzwerkteam.de/freebusy/m.gabriel%40das-netzwerkteam.de.x…

x2go und gpg-agent - no decryption of emails via kmail possible
by Stefan 15 Jul '11

15 Jul '11

Hi all, using x2goclient 3.0.99 on debian squeeze (client and server) together with kmail I run into a problem decrypting emails via gnupg. Unlike as with a Xserver-Session there seems not to be a startscript for gpg- agent in x2goserver. But if I start gpg-agent by hand using command "gpg-agent --daemon" still kmail can't decrypt emails. Starting the gpg-agent with the same command on a xsession initiated with "X -query SERVER" it works. One possible reason I guess in wrong environment variables for $DISPLAY - so the pinentry-qt4 gui (or any other pinentry-gui) could not start. So kmail ends up in "wrong passphrase". This problem allready went up in x2go on debian lenny. But the old kmail on lenny brought it's own frontend for decrypting mails without gpg-agent as a fallback - so it was at least possible to read encrypted emails - even if you had to submit your passphrase on every email again (because it's only remembered through gpg-agent). Any Ideas? Regards Stefan

Building X2GoClient from source
by John A. Sullivan III 12 Jul '11

12 Jul '11

Hello, all. I must be tired, brain-cramping, or clueless. I'm trying to put x2goclient onto a Fedora 15 installation. I compiled nxproxy and nxcomp fine once I figured out the dependencies and symlinked nxcomp-version to nxcomp so nxproxy could fine NX.h. But I then downloaded the x2goclient 3.0.1.18 tarball. I did not see a configure file, a make script, or any templates. I did notice several project files so I downloaded kdevelop to open the project files. I've not used Kdevelop4 before (dinosaur that I am). It only wanted to open the x2goclient-libssh.kdev4 project file. However, it cannot build it and there is nothing to create the configure/make files. How does one build this x2goclient from source? Thanks - John

Keyboardmapping <Alt Gr>-Key
by Stefan LAmbert 11 Jul '11

11 Jul '11

Hallo, leider reichen meine Englischkenntnisse nicht aus um den nachfolgend beschriebenen Fehler in Englisch zu beschreiben. Da jedoch, wie ich weiß, ein Großteil der Entwickler von X2GO aus Deutschland kommt, hoffe ich, dass mir trotzdem geholfen werden kann. Dafür möchte ich mich bereits im Voraus bedanken. Jetzt zum Grund meine Anfrage. Wir nutzen schon seit einiger Zeit X2GO und sind damit sehr zufrieden. Alles hat bisher sehr gut und problemlos funktioniert. Das hat sich jedoch leider geändert. Fehlerbeschreibung: Heute habe ich damit begonnen unsere Testserver von der "alten" x2go-Server Version (3.0.1-5) auf die neue Version (3.0.99.5-0~49~lucid1) umzustellen. Hierzu habe zunächst die alte Version gelöscht (purge) und dann die neue Version, wie im Wiki beschrieben, installiert. Beim Test des Servers habe ich dann folgenden Fehler festgestellt: Wird sich auf dem x2go-Server mittels x2go-Client angemeldet, eine Applikation wie z. B. Libreoffice gestartet und dort dann ein Zeichen unter Verwendung der <Alt Gr>-Taste wie z. b. | oder @ eingegeben, so ist ab diesem Zeitpunkt keine "normale" Texteingabe mehr möglich. Auf dem Bildschirm sind jetzt bei jedem Tastendruck nur noch "Hieroglyphen" zu sehen (Screenshots kann ich bei Bedarf gerne übersenden). Einzige Abhilfe schafft eine Ab-/Neuanmeldung am x2go-Server. Das beschriebene Procedere habe ich an mehreren x2go-Clients (Ubuntu 10.04 und 11.04) und mehreren Servern (Ubuntu 10.04 und 11.04) getestet. Der Fehler ist unabhängig von der x2go-Client Version (getestet mit Vers.3.01-5, 3.0.1.18-0~56~lucid, 3.0.1.18-0~56~natty), tritt aber nur bei der Serverversion 3.0.99.5-0~49 (lucid u. natty) auf. Die Tests habe ich an neu aufgesetzten Maschinen und an "upgedateten" Rechnern durchgeführt. Das Ergebnis ist immer das gleiche. Hier die installierten (x2go)-Pakete eines "Problem"-Servers: (dpkg -l | grep x2go) ii cups-x2go 3.0.0.2-0~33~lucid1 ii x2goagent 3.4.0.5-0~40~lucid1 ii x2gognomebindings 2.0.1.1-0~16~lucid1 ii x2goserver 3.0.99.5-0~49~lucid1 Hier die installierten (x2go)-Pakete eines funktionierenden Servers: (dpkg -l | grep x2go) ii cups-x2go 3.0.0 ii nxcompshad 3.4.0-1 ii pinentry-x2go 0.7.5-2 ii x2goagent 3.4.0-3-1 ii x2goclient 3.01-5 ii x2gognomebindings 2.0.1-1 ii x2goprint 3.0.0-1 ii x2goserver 3.0.1-5 ii x2goserver-home 3.0.1-1 ii x2goserver-one 3.0.1-1 Was mache ich falsch, bzw. was habe ich vergessen? Nochmals vielen Dank für die Unterstützung Viele Grüße Stefan Lambert

Kde4.6 x2goplasmoid
by Mirco Rohloff 06 Jul '11

06 Jul '11

Hello, i want to use the x2goplasmoidbindings on my Kubuntu with KDE4.6. So it is no problem to install the deb pakage. But i can't figure out how this will work. When i put the plasmoid on my Desktop i have a big box with a small toggle switch in. If I press it the session go to sleep. This works good but is not really nice. If I put the X2go Plasmoid in the Kicker-Taskbar i have resice it very high to see it in the bar. That is not usable. Screenshot: http://www.rohloff.de/fileadmin/rohloffde/tmp/kde_plasmoid.png Is there anybody who can give me some tips how this thing can be integrated in the Kde4.6-Desktop. Maybe like the X2go-Gnome Switch near the Logout button! Thanks Mirco

Not a help or feature request here, just a genuine and heartfelt thank you from a java developer who uses x2go on a daily basis.
