[Message part 1 (text/plain, inline)]
Package: x2goclient
Version: 4.0.5.0

Error message:
"VcXsrv windows xserver (X2Go/Arctica Builds) has stopped working"

How to reproduce:
Start an x2go session using the Windows X2Go client, then suspend it. Now
change the resolution for the session and try to reconnect.

Expected behavior:
Well, it would be really, really nice if x2go could change the X11
resolution dynamically, a la VirtualBox/VMWare. Failing that, it might be
nice if x2goclient could query the resolution of the remote session and use
that, or else fail gracefully with a message telling the user about the
mismatch.

This is easily reproducible on Windows 10 Pro x64 client with Ubuntu MATE
14.04 LTS server.

Hi all

New here and trying to move away from NoMachine 3.

I have a Sun Workstation with nVidia Quadro card running OpenSuse 11 and NoMachine 3 (free) and using the latest player and this all works fine.  But I now need to move to a virtual server (no graphics hardware) and while NoMachine works OK there are issues with colours on session restart and performance.

I want to use X2Go but there are issues especially with resuming sessions.

My client is a Win 7 (32 bit) laptop that can have different screen setups
1)On own with a wide small screen
2)At "home" using laptop screen and a 1280x1024 external  - monitor wanted is number 2
3)At "work" using a 1280x1024 and a second wide screen monitor - monitor wanted in number 1

If present I want the X session to go full screen on the 1280x1024, else full screen on the laptop.  The NoMachine client does this very well so at "home" and "work" the session always goes to the 1280x1024 fullscreen without intervention from me.
Using X2Go I can start the session first time OK and I can set it to the 1280x1024 monitor.  I haven't been to the "work" location to see if it will work properly there.  But on attempting to resume the client opens a small window and then VcXsrv crashes.

I tried the pyhoca-gui and this does resume OK but the full screen fills both monitors and I can't find a way to limit to the 1280x1024.  And the mouse wheel doesn't switch between virtual screens.

X2Go session when working looks much better than NoMachines but the resume needs to work.  I sometimes work remotely and if the VPN link drops I need to be able to resume the session when I reconnect.  NoMachine does this job really well.  I don't need this to be automatic but I need the function.
