Hi,
The client shows a weird resizing bug. I want to know what I can do to analyse this further and report it as a bug. I've mentioned this already earlier on the [X2Go-User] mailing list [1].
I'm surprised that I'm the only one seeing this, because I see it on all the environments that I work on. That is, on all PCs where I am logged in with the standard Ubuntu desktop.
My client is Ubuntu (with Ubuntu desktop) and the server side is Ubuntu with a Mate (or Openbox or XFCE) session. Also worthwhile to mention that I don't have my x2go client full screen.
When I move(!) the X2GO window, it resizes(!). And when I keep the mouse clicked on the top bar for the move, (and even if I don't move anymore) it keeps resizing until it reaches the maximum height of my local monitor. BTW. That maximum monitor height is not(!) the maximum height of my local window manager. The maximum height for the X2GO client window is the monitor height minus the height of the top bar.
What I also noticed is that the height increments in steps of 37 pixels. I'm not sure, but I think the the height of the top bar in the Ubuntu desktop is 37.
Here are the last few lines of the remote session.log. I start with a session of 800x600 Info: Screen [0] resized to geometry [799x600] fullscreen [0]. Info: Screen [0] resized to geometry [799x674] fullscreen [0]. Info: Screen [0] resized to geometry [798x674] fullscreen [0]. Info: Screen [0] resized to geometry [798x711] fullscreen [0]. Info: Screen [0] resized to geometry [797x711] fullscreen [0]. Info: Screen [0] resized to geometry [797x748] fullscreen [0]. Info: Screen [0] resized to geometry [796x748] fullscreen [0]. Info: Screen [0] resized to geometry [796x748] fullscreen [0].
Kind regards, Kees Bakker

This sounds like a bug in the _local_ window manager. Do you also see that when replacing the local window manager with e.g. openbox (openbox --replace)?

That is probably because you're not using the standard Ubuntu desktop. Or are you?

When I run the Mate desktop then the problem does not exist. (I may try the suggested openbox --replace in a virtualbox, centainly not on my normal PC environments, at home, at work.)
That tells me there is a bug when the X2GO client is used from an Ubuntu desktop. The question is, how can we find out where the bug is?
Again, I'm surprised that no X2GO user has seen this bug. It makes me wonder if I'm the only one running X2GO from an Ubuntu desktop.

No, I am using kde on debian.

Running another window manager is no permanent thing. You can do that in your running session and then switch back to the old WM using the same method (however, I am not sure what the ubuntu default WM is - maybe marco?). You can also create a second empty user profile just for the purpose of testing. It will not harm you standard session. And it will also not harm your remote session.

Well, switching the local window manager ist my approach for ruling out stuff. If this is tied to the window manager I can probably reproduce this easily.
I can instruct you how to build a debugging version of nxagent/x2goagent to get more information in the logs.

Maybe you have altered some setting in your environment that is falling on your feet now.

You can also create a second empty user profile just for the purpose of testing. It will not harm you standard session. And it will also not harm your remote session. That is only partly true. Ubuntu's desktop is Gnome based, so it is changing certain settings that could influence each other. Just the other day I had a weird double title bar in my gnome-terminal, after I tried Mate for a X2GO test. Luckily that problem disappeared after a restart.

Is that the server side?

Well, the point is, I tested it with a completely new installed Ubuntu with a new user account.

OK. Let's hear it.
Hey,
I really need some guidance, please.
I'm familiar how to build things. But I need to know what program(s) to debug, how to enable more logging, etc. Especially, what are the things to be looking for?
I have two virtualbox VMs that I can use, one as the server and one as the client. I have cloned git://code.x2go.org/nx-libs.git. Is that the one?
