Windows XP guest never starting up in high resolution

Hi,

I start my Windows XP guest (on Linux Ubuntu Jaunty, Virtualbox 3.0.8) always in fullscreen mode. Nevertheless, the guest's resolution is 1400x1050 on boot, thus giving me a black border around the windows desktop. When I hit HOSTKEY-F twice (switch from and back to fullscreen), the resolution automatically adjusts to Ubuntu's full resolution of 1920x1600. Next reboot, it's gone again.

Does anyone know how to keep the high resolution so I don't have to hit the fullscreen key twice? It used to work before, but I don't remember which version (<1.6 I think).

Thanks
Arnuschky

I found that

Code: Select all

VBoxManage controlvm WindowsXP setvideomodehint 1920 1200 32
enables the desired behavior. Unfortunately, it does not stay after shutting down the vm and starting it up again. The setting survives a reboot, though. This behaves like my GINADLL setting. Very weired. Anyone having this behavior as well?

Maybe this thread should be moved to "Windows Guest" forum, no?

At your request, moving to Windows Guests.

My guess is that the last used resolution in windowed mode was 1440 x 900 or similar. Can you try to maximize the window and shut down the Guest, then start it again and see what resolution you get? I don't have a big monitor for your kind of resolution, but all my VMs start with the resolution I left them at, but I hardly use full screen.
