[X2Go-User] multiwindow option and resizing an application window

[Walid MOGHRABI]

Sorry, it's not 4.1.0.0-0~1304~ubuntu14.04.1 but 4.0.1.19-0~1064~ubuntu14.04.1 ... the one in the stable ppa.

Hi, 


I also have an isuse of the same kind that is easily reproducible ... dunno if it is exactly the same issue but it might be related. 
With X2Go Server stable (4.1.0.0-0~1304~ubuntu14.04.1) on Ubuntu 14.04 with MATE Desktop and X2Go client 4.0.5.1 for Windows on Windows7 and Windows10, with Terminator (terminal emulator) in Published Applications mode, when I maximize the application, app goes fullscreen but then, it diminish slowly the get back to pre-maximize size. 

It does that only on Windows while it works normal on Linux. 
Don't know if it will really help in this case but it is quite alike and since it is easily reproducible, it might help to put the finger on this. 

Regards.

When I reconnect it tries to resume and will usually show the desktop for a few seconds and then the connection is killed again. If I do this enough times (3-5 times) it will resume successfully but the window is not resized and I still cannot resize it, but the session is otherwise working fine. 

There should be a logfile on the session on the server, usually in 
~/x2go. Can you check for suspicious messages there? 


I think it is worth trying the upcoming 3.6.x version of the nx-libs. 
Unfortunately you need to build the rpm yourself. Please clone the 
repo at https://github.com/ArcticaProject/nx-libs.git and use the 
specfile in there to build an rpm.

Yeah, have come over this problem, too. But as I am not involved in 
the x2goclient development or packaging I cannot help here. Anyone?

Oh, that shifts focus back to windows again. Mike#2, any ideas? 

answer your question (and isolate it to windows). If not let me know 
and I will pursue getting 4.0.5.1 linux client working on RHEL6. 
According to the bug reports, I would have to update libssh to >= 0.6 
but that is problematic on RHEL6 (apparently it's unsupported because 
I can't even download it from RHN for RHEL6 but I can for RHEL7). I 
will have to install some newer packages in parallel with the older 
versions and update LD_LIBRARY_PATH when using x2goclient... 

> As far as giving you the application, unfortunately this application is proprietary and I do not own it so I cannot give it to you. I know I am not giving you much to help me troubleshoot this and I do apologize for that. If you simply don't have enough information to troubleshoot this problem I completely understand.

If you google for that message you'll find that this is from metacity 
and only a harmless warning. However, I am wondering why the app cann 
be resized at all then. 

Do you see the resizing problem when using another window manager or 
even desktop? Can you sucessfully resize using xdotool? Can you run 
xwininfo on the application window and post the output?

I could try and write a stub application (in motif which this problem application is written in) and attempt to reproduce this problem. That code I could give you. If or when that is worthwhile let me know and I can start on that. 

No, let's try other stuff first.
