This morning I have updated my pc (Kernel 4.8.17, Xubuntu 16.04 LTS, KDE neon 5.9.9 stable) with 168 updates.
After rebooting, in Plasma I have no more mouse gestures: right click on desktop (for contextual menù) > no effect, middle click rolling on desktop > no more changing among the virtual spaces ...
If I right click on an icon the contextual menù appears and if I double left click on same icon then "open" works good.
If I digit "k" in "search..." of "application menù" no programs..
What's happened?
Where are the old configurations?
Thanks.
