RPD not scaling well

[chesterman]

I saw some forums on the web complaining about the rdp session in virtualbox not scaling well. I'm having some weird problems.

I understand that when i connect to my virtualmachine via the embedded rdp server of vbox i'm getting some sort of console session instead of a real terminal server session in the guest OS, so i should change the resolution manually in the video configuration of the guest OS in order to get the resolution i want.

But if I inadvertently maximize my rdp client window (doesn't matter if i'm using mstsc or rdesktop-vrdp), my screen stop refreshing. The session still works, but i have to keep disconnecting and connecting again to have screen updates in order to change manually the resolution back to what was set before.

The host machine doesn't have a GUI, so all the work was done using VBoxManage and VBoxHeadless.

The host is a Debian Lenny AMD64 and the host is a Windows Server 2008 Standard 32bit.

Attach VBox.log of of a session with the problem.

The problem seems to happen in the end of the file

Correcting: The host is a Debian Lenny AMD64 and the GUEST is a Windows Server 2008 Standard 32bit.

The bug persist in the 3.1.6 release.

This is way too vague to work on it. Can you provide more details?

It is an intended feature for RDP clients which support resizing the resolution changes is applied to the VM as well.

Hi Klaus. I don't know which more details that i can give. What happens is that if i resize the window of the terminal session, my screen stop refreshing. In order to operate the remote machine properly, i must keep disconnecting and reconnecting to get a single screen refresh, so i can change the resolution in the guest OS and get screens refreshes properly again.
