Only wallpaper after login

[ouck]

Regulary when I login, I only see my wallpaper: no intro sound, no taskbar. I can move the cursor but it's all, even right clic didn't work.

Code: Select all

$ inxi -S
System:    Host: kingju-desktop Kernel: 4.15.0-39-generic x86_64 bits: 64
           Desktop: Cinnamon 3.8.9  Distro: Linux Mint 19 Tara

Which info can I give you ?

Up, sometimes I have only cursor in a black background...
