When I uninstalled the OpenOffice built-in email tool under Ubuntu8.04, all the items that looked like were removed. I upgraded other software and reminded me to restart. I did it. The taskbar and panel bar disappear. At first, I thought it was caused by the upgrade. I found a bunch of information on the Internet and I was not clear about it. Later, I thought it was the cause of incompatibility caused by the video card Driver Upgrade. After the video card is uninstalled, the resolution is abnormal. Therefore, the sub-card driver is re-installed to fix the resolution problem. Some people later said that gnome-panel was not started.

I used the command gnome-panel and the system prompts that I could not find the command.
So I installed the tool with "sudo apt-get install gnome-panel" and started it. The removed taskbar and panel bar are returned. Switch from graphical interface to command mode and use Ctrl + Alt + F1 ~ F6 and F7 are graphical interfaces, and F8 is a background process. You can also press Ctrl + L to quickly open the file manager. View the gnome-panel process information, and use "sudo ps aux | grep gnome-panel ". (By bengold1979)
