I updated my Ubuntu 16.04 xenial and rebooted the system, but after the reboot no launcher and panel appear in screen. Mouse right click is working, even I can start any applications from terminal it's working fine, but no menu bar for applications are being displayed and many shortcuts are also not working(ex-ALT+TAB to switch between application). I googled it and got so many solutions but none of them worked for me. I installed CCSM tool, tried to delete .config/compiz-1/compizconfig directory, tried some Intel Graphics driver tricks but eventually I end up with no solution.
I created other accounts, for new accounts it's working fine.
