FreeBSD VBox Guest does not run X11 at 1440x900

[Malcolm Matalka]

Hello,

I am running FreeBSD as a virtualbox guest on a OS X.  My Mac is set to
resolution 1440x900 and my X11 config in the VM is set to this as well.
After running freebsd-update fetch and install and upgrading all my
packages I cannot seem to run X in VBox at that resolution.  If I bring
my Mac to 1680x1050, I can run that (but it's not super enjoyable due to
some poor redraw latency).  And I can run at 1080x1024.  I tried
1400x1050, which did not work as well.

What happens when I try to run at 1440x900 is that the screen is only
roughly the size of the console window.  It is running X, I can do all
my stuff but the screen is small.  xrandr claims it is running at
1440x900.

Has anyone seen this?  I feel like the resolution might be a red herring
but I have no way to determine this.

Thanks,
/Malcolm
