This problem actually appeared out of the blue. I've nearly exhausted every option I can find here, but it barely helped.

Here is my situation:

  1. I tried ccsm to enable Ubuntu unity plugin, but every options are unchecked and it seems every time I configure and exit, it revert back to "everything unchecked".

  2. My guest account seems working normally.

  3. Reinstalling ubuntu-desktop and unity also didn't help.

  4. After trying export DISPLAY=:0

    sudo dconf reset -f /org/compiz/
setsid unity

Unity launcher and the panel flashed for a split of a second and then disappeared again

  • Did you try `unity --reset` command? – Danibix Mar 19 '17 at 08:48
  • Yes, the panel flashed and then went away :( – James Wong Mar 19 '17 at 08:50
  • @Danibix here is the output: `unity-panrl-service stop/waiting`,`unity7 stop/waiting`, `unity-panel-service start/running process 3351`,`unity7 start/running, process 3363` – James Wong Mar 19 '17 at 08:53
  • @Danibix I got this when I rebooted the system yesterday. I've currently installed mesa 17 dev version, but it worked as it should before. Should I revert it back to mesa 13 or something? – James Wong Mar 19 '17 at 09:01
  • @Danibix is this really because of mesa 17? I have my guest account working fine though. – James Wong Mar 19 '17 at 09:09

  • @Danibix unfortunately, it was not mesa's fault. Reverting back to mesa 13 didn't change anything. – James Wong Mar 19 '17 at 09:39

I have ubuntu 16.04 and these are the steps that worked for me:

$ sudo apt-get update
$ sudo apt-get install –reinstall ubuntu-desktop
$ sudo apt-get install unity
$ rm -rf ~/.cache/compizconfig-1
$ sudo shutdown -r now
