VB second monitor?

[robbyx]

I am using Ubuntu 14.04 as host. WinXp as guest.

Settings show I have chosen 2 monitors.

Starting VB shows only one monitor ie Oracle VM Virtualbox:1 in the header toolbar

I can not find another VB window. How do I invoke it?

- Right-click on the VM in the VirtualBox Manager.
- Select "Show Log..."
- Save it (just the first log, VBox.log), ZIP it and attach it in your response (see the "Upload attachment" at the bottom of the form).

See log attached.

I found I could get the second monitor to show by going into windows display settings in WinXP, but both monitors go black with white patches presumably clouds in the desktop picture. If I switch back to one monitor in the VB settings, the one monitor is clear and in full colour, but I do not get a second monitor to use.

You gave 9GB to an XP guest. Can't use it! Maximum should be around 3.5GB.

00:00:00.536332   MonitorCount   ...   (1)

You don't have 2 monitors assigned to your guest, you only have 1. Check your settings under Display, Screen, Monitor Count.

00:00:00.536334   VRamSize       ...   60 MB

You can definitely afford 128MB.

Also, you don't have the Guest Additions installed and therefore no 2D or 3D acceleration. For the Guest Additions, see Chapter 4 of the user manual.

I put through your suggested changes, but I still have a problem if I set the number of monitors to 2.

This is a truncated picture of what I see. Although I took a full screen shot, the hosting service has cut it down. The second monitor is completely black.

I have also attached the log file after the changes you suggested.

VirtualBox VM 5.0.24 r108355 linux.amd64 (Jun 28 2016 16:19:57) release log
...
00:00:07.476639 VMMDev: Guest Additions information report: Version 4.3.14 r95030 '4.3.14'

The Guest Additions are too old. You should update them in your guest.

Another thing that I didn't mention is that you have to shutdown the VM completely before posting the log, otherwise it get truncated. And I'm pretty sure I did mention it. ZIP it first.

I have upgraded VB to the latest version, but the desktop is not improved and looks the same as the posted screen shot. See attached for log

The same thing. The second monitor is not working. Host Ubuntu 14.4.3 Server Client Win7 64Bit. After update GuestAddition the same problem. After downgrade to 5.0 everything OK.
