Hi Stefan,

I could not create a LXDE session, I get the message: "Unable to execute startlxde", When I try to create a MATE session I get the message: "Unable to execuate mate-session". I created "Publish Applications" session, but I didn't know what to expect since I didn't see any Desktop.

Regarding the editors, I was using Pycharm.

Here is the output of the debug, when I try to establish connection to the server using the latest version. x2go-INFO-1> "Starting X2Go Client 4.1.2.2..." x2go-WARNING-1> English language requested, not loading translator. x2go-WARNING-1> English language requested, not loading translator. x2go-DEBUG-../src/onmainwindow.cpp:10779> Getting X.Org Server settings. x2go-INFO-3> "Started X2Go Client." x2go-DEBUG-../src/onmainwindow.cpp:575> "$HOME=C:/Users/teiny171950" x2go-DEBUG-../src/onmainwindow.cpp:2266> Reading 1 sessions from config file. x2go-DEBUG-../src/sessionbutton.cpp:361> Creating QPixmap with session icon: ":/img/icons/128x128/x2gosession.png". x2go-DEBUG-../src/onmainwindow.cpp:13290> libssh not initialized yet.

So it seems that non have the suggestion solved my problem yet, any other ideas?

Hi, I have a sticky keys problem, when I connect from windows 10 pc to a linux server using x2Go version (4.1.2.0), connection type: XFCE. Then when I click shift + arrow right in order to mark a specific text and then release the keyboard the text is still being marked until the end of it. Also I cannot stop the operation, I need to restart the session. It happens using all editors, and using all arrows. Unfortunately, the latest version doesn't work, as it fails to connect to the server. Any suggestions?

Looks like you have several issues.

1. Regarding the sticky keys: What happens when you use a different desktop environment instead of XFCE, say, LXDE or MATE? If you don't have them installed and are unable to install them, you could also use "Published Applications" instead of a Desktop Environment for a test. Also, even though you say it happens using all editors, could you name one specifically that we can use to reproduce the issue?

2. Regarding the latest version of X2GoClient not working for you: Please try to install it again, and check the "debug" checkbox during installation. This will install x2goclient.debug.exe alongside x2goclient.exe.

After that, open a cmd.exe on your machine, cd to the installation directory, and run:

x2goclient.debug.exe --debug 2>&1 >%TEMP%\x2godebug.log

Then try to establish a connection. Close X2GoClient when the connection fails.

After that, open the file %TEMP%\x2godebug.log with an editor and paste its contents here.

Kind Regards, Stefan Baur

Hi Stefan,

I was able to understand how to use the publush application mode, So I opened "Pycharm" using the application finder. And the problem exists there too. By the way the problem I am facing seems to me similar to that reported here: https://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=1369 When I reducing the connection to ISDN helped, but the rendering of the desktop became very slow and not usable.

About the log, this is the text that was printed into the command promt: x2go-INFO-1> "Starting X2Go Client 4.1.2.2..." x2go-WARNING-1> English language requested, not loading translator. x2go-WARNING-1> English language requested, not loading translator. x2go-DEBUG-../src/onmainwindow.cpp:10779> Getting X.Org Server settings. x2go-INFO-3> "Started X2Go Client." x2go-DEBUG-../src/onmainwindow.cpp:575> "$HOME=C:/Users/teiny171950" x2go-DEBUG-../src/onmainwindow.cpp:2266> Reading 1 sessions from config file. x2go-DEBUG-../src/sessionbutton.cpp:361> Creating QPixmap with session icon: ":/img/icons/128x128/x2gosession.png". x2go-DEBUG-../src/onmainwindow.cpp:13290> libssh not initialized yet.

About the file x2godebug.log, it is empty (0kb)

Thanks a lot, Tamir

Regarding the editors, I was using Pycharm.

In Published Applications mode, you either get a pop-up with an application list (from which you could start Pycharm or a console window, for example), or, if you set X2GoClient to minimize to the task bar/notification area, you need to right-click the X2Go icon there and you will see a context menu. Select the entry matching your session name, and you will see the list of applications available to you.

...

Here is the output of the debug, when I try to establish connection to the server using the latest version.

[snip]

And that's all? You did close X2GoClient before accessing that log? Very strange.

So it seems that non have the suggestion solved my problem yet, any other ideas?

Well, these weren't suggestions to solve your problem, these were steps to narrow down the cause of your two issues.

Just fyi, I can confirm the sticky repeat behavior on Win client 4.1.2.0 and prior versions using XFCE with geany on Ubuntu 18.04 but also on prior versions and CentOS versions and also on vim or mc. [...] I have recently switched to Win client 4.1.2.2 and have not had the problem since. It may just be statistics and not a fix to any keyboard event queues though. This is not a scientific analysis.

So Tamir should probably investigate why 4.1.2.2 doesn't work for him.

It might be worth trying the latest nightly build (4.1.2.3) instead of the stable version: <https://code.x2go.org/releases/binary-win32/x2goclient/heuler/mingw32-4.8/qt-4.8/x2goclient-4.1.2.3-2020.05.20-a1a2f62-setup.exe>

Unfortunately, that's not very helpful. There's no connection attempt visible (other than a really generic setup).

Stefan's call has been "wrong" in that the order of redirections do matter, and, wwith his listing, stderr-data will continue to get printed out to the console.

Rather try:

x2goclient.debug.exe --debug >%TEMP%\x2godebug.log 2>&1

instead. %TEMP%\x2godebug.log should include text after that.

Also, if possible, please make sure to wait until the connection attempt actually errors out.

Additionally, do you have a file located at "C:\Users\teiny171950\ssh\config"?

If so, what does it contain?
