Hello,
I added Klipper to autostart apps:

Unfortunately it does not starts when I log in. Do you have any suggestion how to fix that?
I use Linux Mint 17.1 "Rebecca" - KDE (64-bit) with KDE 4.13.2

been so long

let Klipper handle the autostart itself by removing it from autostart and then quiting it, a window should popup and ask if Klipper should autostart just click "start"
