Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free.

This question already has an answer here:

In Windows Vista I can switch off via power management: PCI Express Modem port Optical DVD drive

Via network connection I disable: Blutooth

How can I do similar in Lubuntu? Under Power Manager I don't have the options.

It would be good to have a GUI manager for this.

Next Section PM for all pci(e) bus devices, Warning: experimental option, could cause system instabilities..But i found no problem just you have to put usb 2 devices in usb 2 port and usb 3 devices in usb 3 port
