I'm using ubuntu 16.04 LTS
after I shut down the laptop with power button anytime I hover any icon on the left side launcher the screen is flickering(all of the launcher gets hidden for a while and gets back and the applications are still there) and the dash is not opening .the shut down in the menu on top right does not bring the window which makes the laptop shut down.
I found this on google: https://ubuntuforums.org/showthread.php?t=2061180
It requested the following commands:
cat /etc/lsb-release
uname -a
lspci -nnk | grep -iA2 vga
env | grep DESK
the result of commands are:

the same solutions didn't work. I used ccsm to restart the unity. But it again flickers with hovering the luncher's icons.(the launcher gets hidden for a while)
the error report from ubuntu is as following: compiz crashed with sigsev
