Hi,

Since I upgraded to kubuntu 15.10, it takes up to 2 minutes to get full workspace (taskbar, widget etc...).
Before, I had very quick boot (20sec from power to workspace).
I tried to disable every program in system settings, automatic startup, and to start with an empty session, with no change.

Thanks

The same with me.
After I updated from Kubuntu 15.04 to 15.10 it takes more than twice as long until everything is ready, especially the Taskbar/Panel.

Rog131 Yes it looks like what is described in your link, but I did not find a workaround

what has happened if you rename the .cache folder (only to try ...)

It has been resolved, probably with an update
