[p][b]Logitech[/b] manufactures a full range of wireless mice; some of them may be used in GNU/Linux via the included [b][i]Wireless Unifying Receiver[/i][/b], that also accomodates other devices (wireless keyboards, etc). [b]Mice that works in GNU/Linux are advertised as such on the package itself[/b].[/p]

[h2] Pairing [/h2]

[p]Wireless Unifier Receivers and "Nano" Receivers ( A version that only accepts one device per dongle ) can be paired and unpaired with some logitech branded mice and keyboard using the free software (GPLv2) [a]https://pwr.github.io/Solaar/|Solaar[/a] which claims to be a retro-engineered implementation of the logitech's proprietary HID++ protocol.
[/p]

[h3]Experience With Gnewsense-Parkes: [/h3]

[p]If this receiver-wireless keyboard solution is used as primary method of data entry in a setup in which the root mount point is inside an encrypted partition, the receiver doesn't work between its use in the Grub Menu and the loading of the modules by the Operating System, preventing the decryption password from being entered, stopping loading of the Operating System. In order to fix that, append these lines to [b]/etc/initramfs-tools/modules[/b] :
[code]hid_logitech
hid_logitech_dj
#One of the above may not be alway be required and my produce a warning
[/code]

And per instructions on the file itself, one must run [b]update-initramfs [/b] for the change to take effect.
If the changes didn't seemed to take effect, verify that the kernel configuration file in /boot/ have the following values equal to "m" as in "module".
CONFIG_HID_LOGITECH=m
CONFIG_HID_LOGITECH_DJ=m
