Is Solaar still active? Is there a replacement for monitoring Logitec Unifying devices?

Solaar is still active upstream, but has not made any kind of release in quite some time.  The Fedora package should probably be updated but it would just be to another git snapshot which would have another assortment of issues.

Totally untested scratch build of current solaar git tree:

https://koji.fedoraproject.org/koji/taskinfo?taskID=22087446

Thanks.

I took a chance and installed solaar-0.9.2-4.20150528gitcf27328.fc28.7.noarch.rpm

It seems to be working just fine on FC26. It has not exited and is showing all the devices and has survived a logout and logint. Have not tested beyond that. But that is far better than the current rpm on FC26.

Maybe this build can be pushed back to FC26?

I'm a bit confused, because according to that you pulled the rawhide package and installed it on F26.  Which is fine if the dependencies work out, but that package has exactly two commits which aren't in the F26 package:

commit 3aa9aca6812e81597a4023864210ced6c2d84949 (HEAD -> master, origin/master, origin/HEAD)

commit 61495e39fb88611e40dc214120c18cf2d23c826f (origin/f27)
Author: Fedora Release Engineering <releng>
Date:   Thu Jul 27 18:54:17 2017 +0000

    - Rebuilt for https://fedoraproject.org/wiki/Fedora_27_Mass_Rebuild


Neither of these has any functionality changes at all.  So there is no reason why it would perform any better than the F26 package, and there's certainly nothing which could be backported to F26.

If instead you actually tested the untested build I provided then that would be particularly useful information.

Agree with you and sorry for the confusion on my part. The solaar-0.9.2-4.20150528gitcf27328.fc28.7.noarch.rpm eventually has same aberrant behavior as the standard FC26 rpm.

I will test the untested build and report back.

I installed the test build. When it first started, it had the connection to the unifying receiver, keyboard, and mouse. After running for a while, it lost the devices.

The previous rpm would sometimes lose all of the devices. The test build just did. Sometimes on restart, it will have only the unifying receiver, sometimes only the keyboard, and sometimes all three; receiver, keyboard, and mouse.

I have never seen it where is only had receiver and mouse.

When I start Solaar from the command line, I get these messages:

$ solaar
/usr/lib/python2.7/site-packages/solaar/gtk.py:34: PyGIWarning: Gtk was imported without specifying a version first. Use gi.require_version('Gtk', '3.0') before import to ensure that the right version gets loaded.

  from gi.repository import Notify

Took about 20 minutes for Solaar to lose the devices. There were no additional messages in the terminal in which it was started.

Started solaar with -d. Getting messages like this with every mouse movement.

When Solaar lost connection, this is the output in the terminal.

Solaar was still running. It did not show any devices.

Similar problem has been detected:

All I did was log in to KDE.

Solaar loses contact with the mouse and keyboard. It reconnects when stopped and restarted by killing or by logging out of session and logging back in again.

After it has been reconnected for a while, it again loses connection. I suspect it may be because of the KDE Info Center since it also reports on the battery status of the mouse and keyboard under Device Information -> Device Viewer -> Batteries

This just conjecture.

This message is a reminder that Fedora 26 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 26. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '26'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 26 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged  change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

Still happening in Fedora 28, solaar-0.9.2-4.20150528gitcf27328.fc28.8.noarch
