Solution after the taskbar of the centos GNOME panel disappears

Today, I finally made up my mind to install my computer as centos. When I got online, I felt that the top menu bar was out of the way and I deleted it.

That is, the top line of the desktop, and Baidu is fruitless. Google won't be able to go up, So bing is not easy to find the solution!

Symptom: after entering the Linux system, the taskbar on the upper and lower panel disappears, and many programs that come with the system cannot run. Modify the desktop resolution, change the system's Chinese and English text, and restart the desktop.

Methods found on the Internet:
1. Use killall gnome-panel to restart the panel. (The gnome-panel process does not exist)
2. If the above method does not work, delete the configuration file folders.
# Rm-RF ~ /. Gconf/apps/gnome-session

3. If not, delete the configuration file folder.
# Rm-RF ~ /. Gconf/apps/panel

After the restart, the Panel task will return to the initial state, including the insecure warnings for root logon.
