Any other suggestions?
Did you just turn off the laptop mouse or also unplug the laptop transceiver? This sounds like the desktop transceiver is connecting to the laptop mouse as well as the desktop mouse. I can't tell from the Logitech M185 product page if the nano transceiver is one of the 'unified' types. Does is have an orange square pattern on the transceiver? Options: 1. If unified, see if you can find ltunify for your distro https://lekensteyn.nl/logitech-unifying.html#ltunify This may allow setting up the transceivers so that they only "see" one particular mouse. 2. If not, you have 2 transceivers sending on the same 2.4GHz band. One of the devices has to go. Try a different mouse make/model, or go wired for the desktop 3. Build a small Faraday cage for the laptop. Unfortunately this is also block network wifi (a security feature!). -Ed
