It seems to turn off after short inactivity, and while it comes back on again as expected when you press a key, unfortunately the first keystroke does not get registered.Logitech customer service said that the keyboard doesn't have memory to keep its setting. Strangely, to pair it, you have to type in a number and enter, which all works fine. I conclude that our polling may prevent the K780 from getting idle and reset. I log the changes to syslog.I have a k780 and while I have it working with bluetooth, it doesn't seem to want to pair with the unified receiver. In fact, Solaar plays no role when you keyboard turn back on nor it have any influence on input keystroke processing. Your device will completely lost connection after unpaired. )This behavior, while annoying, is not related to Solaar. Forget it. It contains only 3 lines:However there is a problem: the setting may be reset from time to time.I don't see the k780 in the list of devices in docs. Maybe there are some nitpick issues but it's good enough for basic support.Don´t forget to close solaar (system installed) before last command above.I don't know what has influenced solaar to work abnormally. Logitech MK850 wireless keyboard and mouse combo makes it easy to comfortably work across multiple devices for increased productivity. I try holding the key for a few seconds to initiate pairing, and it blinks, but solaar simply times out. Comes in handy if you administer multiple machines in your office.It all worked fine on my Windows 10 machine, until I wanted to use the mouse (not the keyboard) with my Mac. The light on the mouse still came on, but the light on the keyboard (usually comes on when you press CAPS LOCK) was also dead. (By the way, most of the time, the solaar indicator has a wrong icon (a battery icon). I should take a look of it.I check its status with "solaar config K780 fn-swap" every second and set with "solaar config K780 fn-swap false" if true is reported. Logitech is the leader in the Mouse and Keyboard segment. I can now unplug the mouse receiver and use it in my Mac, and when I’m done I can plug it back into the Windows machine and use the mouse there. The instructions suggest that on Windows you need to press fn-P and on Mac OS fn-O to finalize pairing, but pressing either has no effect either.Whenever solaar fails, I just run it to restart the service.I've given up my watchdog (polling) helper, nor will I use the crontab. So my helper tool indeed wakes up every 3 seconds to check the status. I found the simplest way (and with least system overhead) is a tiny script to restart the solaar service. (So don't use the F1-12 keys for the first keypress.
Has anyone gotten it to work?
Is it supposed to work? In particular, what kind of protocol is in use. Maybe some device IDs?Last night, because of a X window hang, I restarted the display manager (# service lightdm restart), and something magic occurred to my solaar system - Now it will pop up a message at up-right corner, telling me my M585 mouse is back from offline (said "powered on"), and my K780 keyboard as well! But that didn't work.Same as I.
My M705 mouse does show up.We still need to face another case - it will lose our setting as well when it's switched back from other machines. The mouse pairs with both receivers just fine.Anyway, as I said before the basic functionality and support is available and appears good enough for daily use.
