Suboptimal display resolution in VirtualBox

This is might be due to #7602 (closed).

Note: My normal resolution is 1680x1050.

Outside of Tails

With the VirtualBox guest packages that are included in Debian, my guest machines work as one would potentially expect. The resolution upon booting is at 1024x768 but if I switch to a full screen display in my virtualbox guest, the resolution matches my workstation’s 1680x1050. At no point is the screen bigger than my display.

In Tails

In Tails, however, the resolution is set to 1600x1200. This means that by default the virtualbox window containing the tails session doesn’t fit on my screen. I can change it after logging in (or just deal with a missing part of the screen), but it’d be better if the resolution could be reduced to something that’s practically guaranteed to work, like 1024x768, 1280x1024, etc.)
