Plasma long loading after login

[john2]

It seems to assume that the machine has Bluetooth hardware, and if not it hangs until it times out. It makes no difference if Bluetooth is disabled. I fixed it by plugging in a USB Bluetooth dongle that was lying about (£1 from Poundland).

I have this on my 2nd monitor too. Black screen, I can move windows into it, but no right click for settings etc.
Disabling Bluetooth seems to have fixed it.

The first thing I did was to disable Bluetooth and then tested the boot time which was unchanged. I then started with an empty session and that decreased the boot time but gave the black auxiliary monitor. So a disabled Bluetooth did not solve the problem on my system.

I also have an auxiliary monitor which does not initialize correctly. It has a black auxiliary screen which I can move applications to and from, but right mouse click provides nothing, including no "Desktop Settings".

This made my KDE panel show up at once. , I never use Bluetooth anyway, I use KDE Contact to have a interface with my phone.

$ sudo systemctl disable bluetooth.service

But how do I turn it on again?

[NoWorries]

On my system, when I "Start with an Empty Session", I get the HPLIP Status Service message with no system tray detected. I also have an auxiliary monitor which does not initialize correctly. It has a black auxiliary screen which I can move applications to and from, but right mouse click provides nothing, including no "Desktop Settings".

For these reasons I have reverted to "Restore previous session" and put up with the extra 23s boot time. I certainly hope that a solution to this problem is found soon.

The times reported here a dismal compared to what was being measured with Kubuntu 13.04. I have an SSD and I am wondering what is slowing the system boot time down so much. Once the desktop is up it is very fast.

I solved the latter problem by following advice here [...] and the former by going into Settings/Start Up & Shutdown/Desktop Sessions/On Login and changing the setting to "Start with an Empty Session".

Hope this helps :-)

And that fixed the other 30 second delay!

Thanks.

Login to working desktop now around ten seconds, down from about a minute.

If you don't need or don't have bluetooth just do:

$ sudo systemctl disable bluetooth.service

And the systemtray will load quickly.

That's brilliant. That fixes one of my 30 second delays - now if I could just work out what the other is caused by.

Thanks!

On my Thinkpad there was a problem with the broadband modem causing slowness and eventually lock up.
Starting up in 14.04 or Windows and then (hot) rebooting into 15.04 would prevent the problem.

I fixed my slow start problem up by going in to the system tray settings and disabling "networks (automatic load)"

Still long loading here too!

[NoWorries]

For me, on my VM of 15.10 (Oracle VirtualBox), Plasma was also taking quite a while to load after the greeter login. Others have suggested/pointed to Bluetooth being involved in this long loading time. As my 15.10 VM doesn't have or use Bluetooth, but Bluetooth packages were installed, I purged all bluez* installed packages except for libbluetooth3 (removing/purging it removes your functioning system/desktop!) and rebooted. Plasma now loads extremely fast after typing in my password.

Sorry to say that I did not get any improvement by purging bluez. I did this using muon as when I used the command line with the purge of bluez* it would have nuked my system. I changed my system to auto login and the times from power on to a desktop was about 49s both with and without bluez. I even tried commenting out the swap file in fstab and that made no difference for me.

I have found that by not having kontact active when shutting down, the reboot doesn't cause problems with my auxiliary monitor not being correctly activated, ie a blank screen.

P.S.

I tried bootchart to get an accurate measure but that failed to generate the file /var/log/bootchart.tgz. So I seem to be snookered no matter what I try to do.

Does seem to be bluetooth related

I updated my wireless card in laptop (the new card included bluetooth). As soon as I booted up with the new wifi/bluetooth card the problem went away. The loading time went from 1min. to about 5 seconds.

I also had slow boot after updating Wily "testing" from the22nd Oct. Upon booting I checked the boot message for errors ( Ctrl+Alt+Tab) which showed something similar to "a start job is runnning for dev-disk-by \ x2duuid-xxxx ".........(37s / 1min30s).
A google search landed me at http://jayshomebrew.blogspot.com.au/...nning-for.html
He sugested to edit /etc/fstab
and comment out the swap file that was used during installation. Reboot, and all should be fine. That fix worked for me
