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.

Linux newbie needs help with solaar (lemmy.dbzer0.com)

Hello I'm a Linux newbie and I need some help. I'm running fedora on my laptop and I want to connect my Logitech mouse. I got solaar installed but I need to manually install the udev rule. I'm following the Instructions here

So I understand that I need to copy rules.d/42-logitech-unify-permissions.rules from the solaar GitHub and place it in /etc/udev/rules.d the thing I don't know how to do is get there. I'm not super familiar with the terminal

Edit : adding this for any future people having the same issue. I booted up my wife's old windows 10 PC, downloaded Logitech unifying software and re-paired the mouse and dongle. Put the dongle back into my Linux PC and the mouse is working. Weirdly though solaar still shows nothing but an empty window. But whatever at least the mouse is working.

Edit 2 : just figured out if I open terminal and type sudo solaar it opens solaar and my devices show up. If I just open it from the start menu or don't use sudo in the terminal solaar opens an empty window.

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?

[–] johnyreeferseed@lemmy.dbzer0.com 2 points 2 days ago

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.
