Auke, no that autotune has always been set to good. It's been discussed already in the RH bug thread I linked to in my 1st post here. I didn't want to duplicate everything already gone through because it's quite lengthy. I'm asking here in case someone has any better suggestions because it should still work the same in theory. No settings have been changed in powertop. It autodetects and sets good for both kernel versions with regards the Logitech unified receiver. To summarise for people who don't want to read the RH bugzilla thread: Autotune service for both kernels tunes the same devices to Good. Nothing is set to Bad. With kernel 4.11.11-300 there is no wake up lag when the receiver and connected device has entered low power state With kernel 4.12.x and 4.13 release candidate there is lag you can measure in seconds and it's extremely frustrating. It causes missed clicks, keyboard characters, duplicate form submissions on websites. Setting the autosuspend for the receiver to Bad is an obvious workaround but it isn't the solution we're looking for. There is a regression here that needs addressing. Hopefully the HID driver contact I found thanks to Joe will be able to advise further on this.
