when entering commands "wingpanel" here is a log appears. window error

  • I'm not an expert at this but I would try to reboot, and then if that doesn't solve the issue, then I would just sudo apt-get purge wingpanel and sudo apt-get install wingpanel again. Commented Dec 23, 2016 at 16:07

Use killall wingpanel in terminal - it should reset the wingpanel and bring it after few seconds. ;)

It happens from time to time.

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.
  • I believe that you don't need to restart your whole system to solve it :) And hey! Terminal is a great way to learn something about system work and how to work with CLI based systems - don't scare our friend ;)

    Do not rm your whole .config directory! That will delete settings from a lot of applications!
