Re: Touchscreen coordinates mangled on X/GPE in RC4

Hi.

FYI, the desynchronisation of my touchscreen and mouse movements may
have been cause by the fact I had a USB mouse connected to the Z at
the same time...

Whenever X is started and the mouse connected, the touchscreen won't
be useable anymore (odd mouse movements)... and in this case, it seems
launching xtscal is a bad idea since it will lead to almost locking X
: no way to click in the right place neither with the stylus, nor with
the USB mouse... unless there's an escape combination to quit xtscal,
maybe (that could be a valuable improvement to add some ? with the
keybord, for instance ?) :(

So I suppose this is the consequence of a weird setup, and may not be
a common problem most users would face ?

Probably not worth filing bugs ?

Best regards,
