I've just installed 11.10 and am having some big problems. After installing updates and programs I wanted I did a restart which was apparently necessary for changes to take place.
Now my unity launcher is completely missing, my nice dark top panel is now the standard yucky grey and I'm missing all the email and user controls on the right hand side of it, including the ones to turn the computer on and off.
Does anyone know how I can deal with this? Thanks!
