Hello
I blacklisted my integrated bluetooth adapter from the USB autosuspend option in TLP by modifying /etc/tlp.conf
. I can see if this change is in effect by issuing sudo tlp-stat
and checking that the power management of the bluetooth adapter is set to “on” (meaning no USB autosuspend) rather than “auto” (meaning USB autosuspend). Or, I can just check directly in /sys/bus/usb/devices/1-3/power/control
.
The problem is that TLP does not apply this at boot, rather only when I manually issue sudo tlp start
.
Note that TLP is enabled and working at boot.
My first guess is that TLP actually does apply the right setting but that then it is overwritten by some other program.
The only other power saving tool I have installed is powertop, however I only use it as a power monitor.
