Just annotations of little "how to's", so I know I can find how to do something I've already done when I need to do it again, in case I don't remember anymore, which is not unlikely. Hopefully they can be useful to others, but I can't guarantee that it will work, or that it won't even make things worse.

Setting asymmetric correspondence between screen and mouse "area"

Like the common acceleration feature, but asymmetric. So you can reach the ends of the screen with whatever range of motion "feels right", even if it's actually "wrong".

You basically misappropriate this spreadsheet:

(Thanks to whomever came up with it!)

Perhaps drawing two rectangles one inside the other may help achieving a more precise "mapping", but one can probably achieve acceptable results just by trial and error.

The principle is to inflate the "touchable" height and width fields, in comparison with the screen resolution, which is kept correct.

For example, for a 1280x1024 screen, I've "faked" a 2200x1780 area.

The spreadsheet is self-explanatory (including the procedure on how to make a copy and use it, written in red, near the top). At the bottom it will generate a "xinput" command.

It may be interesting to keep the defaults saved somewhere, even though I think it would "reset" on reboot, almost certainly. But who reboots anyway.

1.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000
In order to get the correct device name, you use "xinput list" and find your mouse/whatever there. I have the impression that trailing empty spaces are required characters.
