Build a small Faraday cage for the laptop. Unfortunately this is >also block network wifi (a security feature!). OK, first no Faraday cage. That would just interfere too much with my pursuit of karma. :) Second, the M185 receiver does not have an orange square pattern on its transceiver. Third, I looked for ltunify, but the link above took me to a page with instructions for installing from source, and glancing through them I concluded that it was doubtful that it could be done, at least not easily. But that led me to fire up Synaptic and search on 'Logitech,' which turned up a couple of possibilities: logitech-applet and solaar. The former can only change the resolution from the default 400cpi to 800cpi. But Solaar is for pairing and unpairing. I was on the laptop when I did this, so I installed Solaar and launched it. It has a very minimal GUI display, and when I say 'minimal' I mean it displayed nothing. Eventually I figured out that the display was empty because it failed to find the M185 attached to the laptop. This did not surprise me because the M185 transceiver lacked the orange rectangle, and because I paid $10 for it at Wally World. Ya gets what ya pays for, I guess. :( So then I installed Solaar on the desktop, and got the same results. But I have a couple other wireless USB mice around here, so I grabbed one - an M325, whose transceiver has the orange rectangle - plugged it in, and there it was in the Solaar display. And, while it appears in the Solaar display on the desktop, it does not appear in the Solaar display on the desktop. On the desktop I could use Solaar to unpair the mouse, but that would surely deactivate it, so that is not a good idea. A better idea would be to buy a replacement for the M185 still in use on the laptop, one whose transceiver has the orange rectangle. Thanks for pointing me in the direction to a solution. :) _______________________________________________ PLUG mailing list PLUG@pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug
