The wingpannel once dissapeared on me too To fix this, run this command in the terminal. (does not have to be root)
cd $HOME cd .config rm -R *
Then run this to restart the computer.
When you log back in, it should be back to normal.
Tip: if you don't have a terminal in your dock, dont panic! you can always open a full terminal by pushing ctrl + alt + f1. You can go back to the desktop by pushing ctrl + alt + f7. Just remember these things:
When logging in, use the nickname that you chose when installing.
be careful with what you do. The terminal is a great way to ruin your system
- Always remember to use the command "exit" without the quotes to log back out. Failure to do this will result in the shell being open to anyone who passes by your computer.
