Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free.

I just did some routine updates through the Update Manager, and upon the requested reboot, both the unity panel and bar are gone. Desktop notifications are still there, though the rendering seems broken, and it's black opaque where the alpha should be. Luckily I can still run a web browser since I had a Firefox shortcut on my desktop.

I have tried—

  1. Checking CCSM to make sure the Unity Plugin was turned on — It was.

  2. Running unity --reset in the terminal — It said the reset function was "deprecated".

@Jorge et al.: Closing such questions is a good way to prevent growing this site. If the asker knew what the root cause for the issue was he wouldn't ask the question. It may be a bug, but it may be something more specific. I strongly believe we need some place to discuss this before filing a bug report. askubuntu would be a perfect means... –  cfi Jan 27 '13 at 11:15
