Hi,
After an upgrade from debian wheezy to jessie, my user can not display the desktop manager. It start regularly, Software's windows, automatically loaded, react resizing, I can move through virtual desktops, but I have no taskbar, menu, wallpaper, etc. But I can connect to the other windows managers. Others users can open their kde 4.14.2 sessions correctly.
Comparing ~/.kde/files, between a new user and mine, it appears that what is links in the new user, pointing toward /tmp/ksocket-pierre and /tmp/kde-pierre and /var/tmp/kdecache-pierre, are empty directories on my common user : pierre.
Have you ever heard someone has the same problem ? I tried to remove the ~/.kde directory, but it does nothing. I have searched for QDBus error etc. but I didn't find correct answers.
Could someone help me

answer : delete /var/tmp/kdecache-myuser/
