Someone's going wrong opensuse 42.1 KDE leap from today's updates 09/14/2016?
I have a feeling that the problem is the access to the encrypted home. The system is almost clean, reinstalled it two days ago. Until I updated this morning went well.
Goes so slow it is unusable, it takes about a minute to load applications, have a ssd and i7, everything has always gone very fast. I am now from Linux Mint KDE 18.

Greetings and thanks
