After installing regular system updates yesterday and rebooting, suddenly Launcher and menu bar are missing, Tried looking for answers under similarly titled threads but nothing I've tried seems to help. Tried disabling and re-enabling unity in Compiz. I'm really new to Linux and not very familiar with it yet. I am trying to learn but have not had any luck with everything I've tried that was suggested in the other threads.
The only way I'm able to do anything right now is that I can make the launcher and menu bar reappear (temporarily) when I type unity --debug into the terminal which results in this:
~$ unity --debug
unity-panel-service stop/waiting
unity7 stop/waiting
unity-panel-service start/running, process 5114
