#3725 obsolete Display problems on Windows 2003 after reboot (4 bit color, 800x600 max), no resize Tiago Fernandes
Description

I use virtual box for a while, on my laptop (windows XP SP2), and a windows 2003 server web edition guest. Some time ago, I had to restart my VM because of a source safe fix I installed. When the VM restarted, it was on 4-bit color mode and 640x480 resolution. I tried to change color and resolution, but the max I can get is 800x600 4-bit color.

Well, I updated virtualbox version three times (first to 2.1.0, then to 2.1.2, now to 2.2.0), removed additions, re-installed additions, etc., changed video memory (was 128M initially), but still the same problem.

Then I removed VirtualBox Graphics Adapter. Now I have 32-bit color mode and higher resolutions. Mouse pointer integration works fine, shared folders, etc. all works nice. The problem is that the guest display is not dynamically resizing as I resize the VM window.

After searching the forums and trying a lot of things, including re-installing virtual box, I even tried to run this VM on my desktop Mac. The VM behave exactly the same way it did on my XP laptop.

My temporary solution to work with this VM was to start it in headless mode, then connect to it via terminal services client (not to virtual box RDP, but to windows terminal services). This way, when I maximize terminal services client, I get full screen used.

Ok, this is a *temporary* solution. I'd like to have the same behavior I had before, resizing my VM window and getting it display resized accordingly. I've passed last 3 days digging in the forums, trying to find someone with the same problem, trying all solutions I could find for display problems, but nothing. It seems I am the only guy with this problem...

laptop: LG P1 Pro Express Dual
cpu: Intel Core2 T7200 @ 2.00 Ghz
ram: 3GB @ 997Mhz
graphics: ATI Mobility Radeon X1400
os: windows XP sp2
virtualbox: 2.2.0

#3736 obsolete 24-bit color depth warnings with Windows 7 + Guest Addition Jim Avera
Description

Updated to VBox 2.2 and now a pop-up warning appears every time a Windows 7 VM is started saying that the virtual display is set to 24 bit color depth but should be set to 32.

However, Windows 7 thinks the color depth is 32, as indicated by the following:

Right-click desktop->Screen Resolution
Click <Advanced settings>
Click <List All Modes>
The highlighted mode is "1400 by 1050, True Color (32 bit), 60 Hertz"

So it seems like either Windows 7 is reporting the wrong mode (the resolution is correct, at least), or the Guest Additions and/or Vbox is incorrectly giving this warning.

Re-installing the new Guest Additions and rebooting the guest did not fix the problem.

#3747 obsolete Virtualbox Crashes on Mac Host When Using OpenGL 3D Caleb
Description

When I use 3D applications with the 3D acceleration turned on, I sometimes get crashes. The VM will freeze for a few seconds, the spinning colored pinwheel will animate, and then the VM will close without displaying the standard Mac OS X application crash dialog. I have attached a log of the VM from a session that crashed.

I was running YSFlight (http://homepage3.nifty.com/ysflight/aircraftsoft/aircraftsofte.html) on a Windows guest with Intel VT-x enabled with nested paging. I am running this on an early 2008 Macbook with Intel GMA X3100 graphics.

When I run Virtualbox on a Windows Vista host on the same Macbook with a Windows 7 guest with 3D acceleration and YSFlight, I don't experience this problem as often. I have also noted crashes with an Ubuntu Linux 8.04 guest with 3D acceleration in the new Virtualbox 2.2.0 release.
