Yes, I'm aware of that. However 'tracer' supposed to detect this, either when called from the Shell or via the dnf plug-in. That's why it's telling me to restart the session.
I seriously doubt that tracer will be able to detect that some processes may survive a log-outt/log-in event.
Naturally not, but it should (and AFAIK does) detect libraries being updated and recommend that processes using them be restarted.
Do you run tracer again after logging in again?
I sometimes run it from a root console while the user session is logged out, and make sure nothing out of date is still hanging around. This doesn't appear to correlate with the problem, but I haven't been systematic enough about it to be sure.
Therefore, I don't logout/login after updates. If anything, I reboot. In my case a reboot takes about 12 seconds so I'm not bothered by it.
It's fast here too, but I usually have a VM running that I may not want to forcibly reboot.
There is always something, isn't there?
Yes, Murphy had something to say about that ...
And I just had lightdm screw up royally. First, upon login I got an XFCE polkit error popup, which is singularly useless in telling you anything you can troubleshoot with. Then, I had no access to the sound hardware on my machine, nor could I enable/disable wireless, play with firewall settings or anything else, as polkit thought I didn't have permissions to do anything, nor did it ever pop up an authentication dialog.
I wiped my xfce settings, reinstalled lightdm, xfce4-polkit and anything else I could think of to no avail. I finally just punted, disabled lightdm and enabled lxdm and everything started working again.
Very, VERY frustrating.
