From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Try unplugging and replugging your logitech dongle, sometimes solaar needs to see the dongle appear to figure out that it's there.
Tried that, no luck. I'm starting to think it might just be a hardware issue. It's a mouse and keyboard I haven't used for a while.
Is it just the mouse and keyboard that aren't showing in solaar, or the unifying receiver itself?
For context, this is what a unifying receiver with a mouse and keyboard paired to it ought to look like in solaar:
Not even the unifying receiver seems to show up in solaar. When I plug it in I get a notification saying Logitech unifying receiver has been plugged in on my task bar. But then I open solaar and it's just a blank window. I also tried it on my other PC that's running bazzite and it's the exact same thing. I also had 2 unifying receivers and I tried them both just to rule out a broken dongle.
I'd check with other USB ports then. If the receiver is not even detected, it's often a defective USB port.
I tried every USB port, they all detect when the dongle is plugged in but solaar just displays a blank window. I even tried it on my other Linux PC and it had the exact same thing happen . I also had a second dongle so I plugged it in to time rule that the dongle was broken.
Silly question, but you have tried turning the computer off and back on again, right?
Yes I did, even tried a different PC which is why I think It might be the hardware. I might see if my buddy from work can plug it into his windows PC to see if it works. That way I can definitely know if it's a hardware issue.
