[Xorg] Dynamic mouse accelaration

[Peter Postmus]

Hi,

One thing that kind of bothers me is the implementation of mouse 
accelaration in both the XFree86 and X.org servers. If the mouse is 
moved fast enough (beyond a threshold), the pointer on the screen is 
moved faster. Although both the threshold and the accelartion factor are 
configurable, it still feels a bit unnatural to me. Especially when 
compared to MS Windows' mouse behavior.

Therefore, I would love to see dynamic mouse accelaration in in the 
X.org x-server, setting the accelaration factor depending on the speed 
at which the mouse is moved. The user could then control the amount of 
accelaration that is added, independent of the speed at which the mouse 
is actually moved. For example, if the accelaration factor for a given 
speed of mouse movement is normally 2, and the user wants less 
accelaration, he could set it so that the accelaration factor would be 
decreased to, say, 1.5. Accelaration at other speeds would be affected 
as well. For example, if accelaration at a higher mouse movement speed 
is normally 4, it would be decreased to 3 in this case. So the user no 
longer controls the absolute amount of accelaration, but instead the 
relative accelaration. The threshold would still be possible to control, 
functioning as a point after which accelaration is applied (as it is 
now). In short, the user could say: "from this point on, start 
accelarating the mouse by the relative amount I have entered".

Unfortunately, I don't have enough knowledge of the X.org architecture 
to implement this and test the mouse "feel". And I don't know if this 
functionality is allready included in any development version.

What do you think?
