  • Making a Powertop tunable permanent

    From Ar@2:250/1 to All on Tue Jul 20 17:05:31 2021
    After every reboot (new kernel), I have to go in to Powertop to change
    the USB receiver for laptop mouse and stop it going to sleep. Is there
    any way of making the change permanent?

    When I make the temporary change, it flashes up at the top of the console...

    echo 'on' > '/sys/bus/usb/devices/5-2/power/control';

    It changes from echo 'auto' before changing the device to "bad".

    If that is all it does then you could put that line into
    /etc/rc.d/rc.local (making sure rc.local is executable as owner-group)

    Off hand, I think the easiest way would be to use rc.local.

    As root, "touch /etc/rc.d/rc.local" "chmod a+x /etc/rc.d/rc.local", then edit the file and append the line ...
    echo 'on' > '/sys/bus/usb/devices/5-2/power/control'
    to that file so the script is executed on every boot.

    There are probably other ways to accomplish the same thing.
