--- Comment #8 from Ivan Bordoni <ivan.m...@fastwebnet.it> --- Ok I've solved !!!!! The problem, it comes from the database ~/.local/share/kactivitymanagerd/resources/database it was corrupt ...I have not tried to empty it but I simply deleted it: ~/.local/share/kactivitymanagerd/ and now everything works correctly ...but now I can not explain why this kind of problem, here are the things I was doing before the problem: - after a login I found the latte-dock of the primary display, strangely out of position and on the 55-inch TV secondary display - I played on the management of the displays to reposition the latte-dock - I restarted and here appears the problem described above Thanks so much guys for support -- You are receiving this mail because: You are watching all bug changes.
