First, go to the System Preferences and hover the mouse over the entry for the daemon. It will show you the location, which should be /Library/Application Support/Logitech/LCCDaemon.app (you won't see the.app part when you go to the folder location). Launch System Preferences. Click on Security & Privacy, and then click the Privacy tab. In the left panel, click Files and Folders and in the right panel, check the boxes under Logitech Control Center Daemon. Click here for information on macOS Catalina and macOS Mojave permissions on Logitech Options.
Linux led controller for Logitech G213, G410, G413, G512, G513, G610, G810, g815, G910 and GPRO Keyboards. I've found a lot of stuff snooping around in the files of the Logi Options and the Daemon associated. I figured out some ways where I could (kind of) turn them off. Although it was tedious and only one by one, and still, they were mainly just relegated to the main screen (So woopie for desktop switching). I'm praying for an update here. I have a 2020 MacBook pro 16 and Logi Options Daemon is 8% of my battery power. What could possibly require this kind of overhead? I would have thought less than 1% if you would have asked be beforehand.
The Logitech Unifying Receiver is a wireless receiver using 2.4 GHz band radio communication that can connect up to six compatible wireless mice and keyboards to your computer.The input device that comes with the receiver is already paired with it and should work out of the box through plug and play.Logitech officially supports pairing of additional devices just through their Windows and macOS software.
Pairing and unpairing on Linux is supported by a number of tools, listed thereafter:
ltunify is a command-line C program that can perform pairing, unpairing and listing of devices. Solaar is a graphical Python program that integrates in your system tray and allows you to configure additional features of your input device such as swapping the functionality of Fn keys. libratbag is a configurable mice daemon that allows you to configure your devices, it has a GTK based graphical frontend app, piper.
Several solutions are available:
The following packages use the
plugdevuser group, create it if it does not exist, and add users to this group to avoid the need of running these as root:
Do not forget to relogin to apply user's group membership. After installation, run
and then replug reciever. After that you will not need root permissions.
pairingtool can only be used for pairing and does not provide feedback, it also needs to know the device name for pairing. ltunify, Solaar and libratbag can detect the receiver automatically.
Examples on unpairing a device, pairing a new device and showing a list of all devices:
Solaar has a GUI and CLI. Example CLI pairing session:
To disable autostart of Solaar, remove
Currently, piper is not able to pair/manage devices for unifying receivers but libratbag does include a
lur-command command line tool that is able to do this.
To find the device that the receiver has, therefore take a look at the outputs of
This will show the names of your receiver, for example
Now switch off the device that you want to pair (if it was on) and execute your compiled program with the appropriate device as argument:
Now switch on the device you want to pair. After a few seconds your new device should work properly.
On some systems there is more than one device that has the same name. In that case you will receive the following error message when the wrong device is choosen:
With kernel 3.2 the Unifying Receiver got its own kernel module hid_logitech_dj which does not work flawlessly together with keyboard layout setting set via xorg.conf.A temporary workaround is to use xorg-setxkbmap and set the layout manually. For example for a German layout with no deadkeys one has to execute:
To automate this process one could add this line to xinitrc or the according autostart file of your windows manager respectively desktop environment.
The Logitech keyboard K400r with integrated touchpad comes with Logitech unifying receiver M325 so the above mentioned about the keyboard layout will apply here too.
Also the integrated touchpad is recognized as 'pointer' instead of 'touchpad' so you cannot use the Touchpad Synaptics drivers.Two finger horizontal scrolling and tapclick will work but in order to have a middle mouse button emulated you will have to add
to your evdev.conf. Now third button is emulated by pressing both buttons simultaneously.
Is it possible to have the error:
In this case, you can physically remove the Unifying Receiver and re-insert it, and re-run the command (as described in the second point of installation part on the official site ).
While booting it's impossible to input anything with a Logitech wireless Keyboard (e. g. Logitech MK700).The cause of the problem is the own hid module for Logitech devices since Kernel 3.2.
A workaround is adding hid-logitech-hidpp to MODULES in
and recreate the initrd for the kernel:
Several security vulnerabilities of the system have been reported and you may be in particular affected by the MouseJack Vulnerability if your firmware has not been updated recently.
It is possible to display the current firmware's version by running:
RQR12 firmware with version earlier than
012.008.00030 and RQR24 firmware versions earlier than
024.006.00030 are affected by this vulnerability and should be updated.
The firmware can be updated using fwupd like so:
If everything looks good, apply the update:
Follow the Solaar USB installation instructions.
Because the receiver uses the 2.4 GHz frequency band also used by Bluetooth and Wi-Fi 802.11, it is possible in some circumstances of heavy Wi-Fi usage close to the receiver to experience lag or disturbances in communication with the devices. This is unlikely because the receiver confines its communication to channels unused by the majority of 802.11 solutions and it is able to quickly change channel within the band if it detects any interference from another device. However, some users have experienced interferences.
Switching on/off the device will force the search for a 'quiet' channel and may solve the issue.
This problem can also manifest if there is electrical noise from USB3 sockets on the motherboard, and it is located close to or in one. Moving the receiver to a USB hub or the end of an extension cable may fix this.
If you have several receivers in system, for example you use multi-device keyboard and mouse and passthrough one of the receivers while using pci passthrough setup and after you turned off your guest machine, that receiver got appeared in the host OS, the input may become laggy. While mouse moving is good, the scrolling with wheel is unacceptably slow (scrolling step is very small). In that situation, unplugging and replugging the receiver may help (however, it may fall to this laggy mode just after several seconds again). Also if you use multi-device peripherals (for example, MX Master mouse), you may just reswitch to the current port with the device-number button.
