Using Ubuntu VM on remote windows computer. Choosing VboxVGA gives me an offset cursor, Choosing VmsVGA won't autoresize window

Question

I have a problem running Ubuntu 14.x (no choice) in a VM on a client's computer which I access via RDP:

When I select "VboxVGA", my mouse cursor is display to the right and lower of the actual cursor position as detected by hotspot highlighting or text select or window resize, etc.

But if I use "VmsVGA", the cursor tracks well, but I have use `xrandr --size 1680x1050` to get the screen to expand.  When I look at the view menu, `View->Auto-resize Guest Display` is grayed out.

Either solution would be acceptable:

1. (In VboxVGA) "Why is my cursor pointer is offset to the right and down from where linux thinks it is?"

2. (In VmsVGA) "Why won't VmsVGA allow autosizing?"

And yes VboxVGA DOES Autosizing, and VmsVGA puts the cursor in the right place.

I'd love a solution for both, but either will do.
