Arf, the shoemaker's syndrome always badly shod! The computer technician (engineer?) Who does not back up his script before updating! hi hi ha ha oh oh! I know that too! I do not stop tinkering the Salfter files to have a little more details at my convenience on the MPH-Switch, but I do not know where the original files at all. But anyway, my changes are very minimal because I do not understand much about Python. Even some Bash script goes beyond me then ... For example I can not reproduce this manual command of nvidia-settings that would allow me to reduce a little fan speed when they make too much noise annoy me.

Post us your script with an explanatory comment on the changes made. At least it will be here and therefore saved in some sorts.
