The gui-based controls for mouse acceleration do not suffice to tame my mouse, so I am correcting this by running:
xinput set-prop 10 "Device Accel Constant Deceleration" 2.9
This script has the desired effect (every time) when run manually from the terminal. However I have yet to find a way to run it on each login. Attempts to have it execute through rc.local or using the script launching options in the system settings have both remained fruitless.
Do you have any suggestions of what else I could try? Should I modify X11 config files directly? Several posts related to this topic advised against doing so.
