[Bug 1509334] Re: KDE/Plasma very slow to launch (Kubuntu 15.10)

[Philip Muškovac]

** Description changed:

- On my four PCs upgraded from Kubuntu 15.04 to 15.10, I have the same
- problem: for two days, KDE/Plasma is very long to launch. The desktop
- begins to appear but I must wait nearly one minute for all plasma
- widgets and icons to appear. And I repeat, this is happening on 4
- different machines !
+ [Impact]
+ Plasma NM does synchronous DBus calls do bluez for the bluetooth status, which in some situations can take up to 30s to finish/reach a timeout.
+ As Plasma itself waits for Plasma NM to initialize, this can cause the Plasma login to take half a minute without any response.
+ 
+ [Test Case]
+ First of all, you need a system that is affected by this.
+ - Try to log in an see that it takes unusually long to do so (~30s)
+ - Enable wily-proposed and update plasma-nm
+ - Reboot and verify that the login now takes 5-10s
+ 
+ [Regression potential]
+ This is mostly just reworking existing BT activation code, so the worst that should happen is the adapter getting enabled a while after the Desktop finished loading. As that's a normal use case when you enable an adapter by hand later on this shouldn't cause any issues.

+ [Original Description]
+ On my four PCs upgraded from Kubuntu 15.04 to 15.10, I have the same problem: for two days, KDE/Plasma is very long to launch. The desktop begins to appear but I must wait nearly one minute for all plasma widgets and icons to appear. And I repeat, this is happening on 4 different machines !
  
  Once everything is finally launched, the system seems OK.
  
  Update: removing the network manager app from the taskbar solves the
  problem.
