I am having trouble with the Ubuntu VM not displaying the same size from session to session. I adjust it to the size I want, then when I leave and return, the VM displays at the default size again. I looked in the configuration options for the VM and didn't see anything, so (and I am not sure this was the correct way to approach it) I tried setting the display size within Ubuntu and ended up with error messages every time the desktop loaded. What is the correct method of setting and saving the display size settings so that the VM restores back to the same size I want it?
