Hi, I just changed from Ubuntu 14.04 (flawlessly working) to 16.04 and experienced a similar behavior of my Logitech, Inc. Cordless Mouse: after a few seconds of inactivity, the mouse exhibits a lagging behavior. Interestingly, using a USB cord connected mouse does not show this behavior.
I searched the WWW and tried all proposed actions without success. However, I have not found THIS bug report. Finally, as a last random resort, I decided to fully disable the laptop mode ENABLE_LAPTOP_MODE_TOOLS=0 in /etc/laptop-mode/laptop-mode.conf and the problem disappeared. After that finding I searched the web regarding bugs in laptop mode and found this entry. A few information: lsusb yields (only the interesting line displayed here): Bus 003 Device 002: ID 046d:c501 Logitech, Inc. Cordless Mouse Receiver Relevant output of usb-devices: T: Bus=03 Lev=01 Prnt=01 Port=02 Cnt=01 Dev#= 2 Spd=1.5 MxCh= 0 D: Ver= 1.10 Cls=00(>ifc ) Sub=00 Prot=00 MxPS= 8 #Cfgs= 1 P: Vendor=046d ProdID=c501 Rev=09.10 S: Manufacturer=Logitech S: Product=USB Receiver C: #Ifs= 1 Cfg#= 1 Atr=a0 MxPwr=50mA I: If#= 0 Alt= 0 #EPs= 1 Cls=03(HID ) Sub=01 Prot=02 Driver=usbhid I did not find any error or warning messages in the log files. So this is definitely a bug in or wrong parametrization of the laptop-mode tools or the programs invoked by laptop-mode. It would be good if this could be corrected in one of the next updates given the fact that this bug persists now for more than a year.
