I had the same problem.
I fixed it by installing the guest additions and then editing the
xorg.conf file.
First add a driver line to the Device Section to specify the virutalbox
video driver as shown below.
Section "Device"
Identifier "Configured Video Device"
Driver "vboxvideo"
EndSection
Next add a default depth line and a Display Subsection. In the display
subsection you list the mode you want to support, with the first one
listed being the default. My screen section looks like this:
Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "1024x768" "800x600" "640x480"
EndSubSection
EndSection
And works fine at 1024x768.
