How can I create launchers on my desktop?
I have just upgraded from 11.04 to 11.10. Everything worked fine at first, but at one point when I was editing some CompizConfig settings (just something basic like 'number of desktops'), CompizConfig crashed. Then the whole launcher disappeared, along with most of the buttons in the top panel. The shutdown button, calendar, etc. all went, leaving just the tabs from File to Help.
Also, windows now have the title and File, Edit..(etc) tabs on 2 separate lines, instead of the new format where hovering over the bar switches which one is visible.
I have since been using Ctrl+Alt+T to open a terminal and open applications, shut down, etc, from there.
I have typed in the command: unity --reset which has some effect, but the terminal never reaches the end of the task. I've also done apt-get update, which completed fine.
Can anyone help me restore the launcher and panel functions?? I am getting most frustrated by the fact that once I have opened Firefox, I can't enter any other commands!
