After suspend, Bluetooth indicator flickers in greeter and wingpanel unresponsive on logging in #192

Closed jeremypw closed 1 year ago

What Happened?

I have noticed that recently wingpanel often becomes unresponsive (more than once per day) and can only be fixed by killing and restarting from the terminal.

I have not determined the trigger but have noticed that while in this state htop shows that there is very high activity on the messagebus and network manager processes (almost 20% of cpu)

Another posssibly related observation was that after waking up from suspend, in greeter, the bluetooth was flickering rapidly on and off. On entering the desktop the wingpanel was found to be unresponsive. After restarting the wingpanel and suspending again the bluetooth indicator no longer flickered in the greeter on rewakening.

Steps to Reproduce

Usually occurs after switching bluetooth on in session and then suspending for a while. On reawakening the bluetooth flickers rapidly in the greeter and the popover switch shows it is switching on and off rapidly. On logging in, bluetooth indicator shows "off" (i.e. is not restored as expected) and the wingpanel is unresponsive.

Expected Behavior

The wingpanel remains responsive.

Running wingpanel from a terminal and waiting for a hang gave the following output, apparently in an infinite loop:

Confirmed that when this issue occurs during suspend, the bluetooth indicator is rapidly switching on and off. Maybe related to commit ce88a7b03231b59c57f832aa656b4763d7d1e77e - it started about the same time. I'll try running a branch with this commit reverted.
