[sugar] commanding what the screen should show

[Mikus Grinbergs]

This too might have a bearing on the "jumpy cursor".

I normally use Terminal (in the Sugar X session).  But sometimes I 
use the text console (to get there, I press ctl-alt-F2).  To get 
back to Terminal (i.e., Sugar), I press ctl-alt-F3.

No matter how carefully I press those keys (on a good-quality 
external keyboard), I often end up looking at Home view.  In fact, 
just today when coming back from the text console (I think it was to 
Joyride 2330), I was shown the Terminal screen and managed to type 
in one character -- then the XO changed the screen to Home view.


It seems to me that the XO had "stacked" my last keypress (the F3), 
and upon resuming Sugar had "fed in" that stack.  F3 is what asks 
for the Home view - and that's what I got - despite, from the text 
console, being careful to press F3 only once (for the ctl-alt-F3).

In this situation, the XO behaved as though it had been presented 
with more "input commands" than I had entered.  [I have no reason to 
believe that the keyboard was at fault.]


If this guess of mine were correct, that might explain "overshoot"
of a cursor movement - instead of acting on a _single_ cursor
movement as input by the user, the XO might behave as though it had 
been presented with _multiple_ movement inputs.
