RDP stops working correctly. Client can connect, but screen is black. -> Fixed in 2.1.2

[tale]

I've had this occur several times in the past few days. I have a headless setup running on Ubuntu with Windows XP running as a guest. If the network connection drops or I kill the rdp client that is connected, then it will occasionally show a black screen when I reconnect. I've tried reconnecting multiple times with different clients (Windows RDC and rdesktop-vrdp) and the screen is always black.

The only way that I can fix the rdp connection is to shutdown the windows xp guest. Restarting Windows XP doesn't fix the issue.

After a complete shutdown, I can restart the guest and then the rdp connection is fine again.

Please attach VBox.log with this problem.

Should be fixed in 2.1.2. Please reopen if the problem persists.

Same problem here: Headless Ubuntu Server 10.10 host and Windows 7 64-bit guest. VirtualBox version 3.2.12

The network drops connection from time to time (bad CPL connection it seems) and when it gets back, I get a black screen. The only way to fix it is to halt the virtual machine and restore it back.

This might be linked to the following ticket where I attached the log: ​http://www.virtualbox.org/ticket/4655

Please reopen if still relevant with VBox 4.2.14.

I have the same problem with 4.3

Archlinux 64bit Host After some connects/disconnects the display stays black Most of the time it helps to do

VBoxManage controlvm myvm vrde off
VBoxManage controlvm myvm vrde on

Sometimes guest vm aborts while doing this. Will post a log when it happens the next time. Edit: Attached a log now where rdp stayed black. Last Line:

02:39:11.369000 VRDP: DisableStatus timed out 5000!!!

Edit2:

Does not seem to happen if multicons are disabled:

 VBoxManage modifyvm myvm --vrdereusecon on --vrdemulticon off

VBox Log when rdp stays black

Please try to reproduce the problem with 4.3.2 extpack. There was a fix which might help in this case.

Currently you have an older extpack: Oracle VM VirtualBox Extension Pack (Version: 4.3.0 r89960; VRDE Module: VBoxVRDP)

Please reopen if you can reproduce the problem with the 4.3.4 ExtPack installed.
