I had run apt upgrade a couple of days back, and restarted my PC a while after, when the top bar and the launcher disappeared. I have tried all the following solutions, but none of them worked:

  1. Reinstall ubuntu-desktop

  2. Removed Unity entirely and reinstalled it again.

  3. Using dconf reset and setsid unity
  4. Enable Ubuntu Unity Plugin
  5. Running unity --reset or initctl restart unity-panel-service just flashes the top bar and the launcher and disappears again.
  6. Removing the compiz-1 folder
  7. Removing the .compiz folder

EDIT:

  1. All upgrades installed + compiz-core is already the newest version(20170630)

I have been searching for solutions for days now without any luck. Although the above solutions have been working for others, none of them seem to work for me. How do I fix this?

Currently running Ubuntu 16.04.3 LTS.

Update: Yesterday I tried advice from WinEunuuchs2Unix answer in ubuntu-menu-and-launcher-not-showing-after-2-16-2018-update and it fixed the problem in my case.

rm -rf ~/.config/compiz-1/compizconfig/*

I have tried to remove it before, but nothing changed. And just after mesa downgrade, and then removing compiz config files Unity panels come back to their usual places. But I still can't understand what was the main cause of crashing.
