That helped, although as you said, disabling the mouse grab option part of 
that makes the game unplayable.

Here is what I found before I tried the --log --nograb options:

Removing the external monitors made no difference. Changing the resolution on 
my laptop screen made no difference.

When I moved the Enigma game window around the virtual desktop, I found that 
the mouse event numbers got smaller the closer to the upper left corner I put 
it. I could never get it close enough to the upper left corner top actually 
work. The smallest numbers were in the 2000 range. When I moved the window 
toward the lower right corner of the virtual desktop, the numbers could get up 
into the forty-some thousands.

When I changed the size of the virtual display screen, the numbers in the 
mouse event output looked like the virtual screen was always something like 
45,000 or maybe 50,000 in size. Wherever the Enigma window was and whatever 
size it was, the mouse event numbers looked like they were based on the 
position of the mouse within the virtual desktop. For example, if I set the 
desktop to be as big as I could and set the Enigma window to be as small as I 
could, then when I put the Enigma window in the upper left, the mouse event 
numbers could get as low as in the 2000's. But if the virtual display was set 
to a smaller resolution, the enigma window occupied more of it, so when I put 
the Enigma window in the upper left, the mouse position of the ball was 
farther away from the upper left corner as a proportion of virtual display 
screen size, and the mouse event numbers could not get lower than the 
20,000's. In other words, imagine that no matter what the resolution settings 
in the VM, no matter how many or few pixels the desktop is, when I started a 
level the mouse events showed where the ball is in a coordinate system that 
scales to make the desktop approximately 50000x50000.

Here is what I found trying enigma --log --nograb options:

I was able to control the ball with mouse properly, although it was a bit 
erratic when I set a very large virtual screen size and scaled it to fit on my 
physical screen. The mouse event numbers were in the two digits range and some 
of them were negative numbers. If there was an option that did the same thing 
for relative mouse without disabling mouse grab, that might work.
