How to retrieve that I kill accidentally
 

Hello I am having problem retrieving the desktop that I accidentally point out and clicked on it by xkill. How can I retrieve it?

if you're at a command prompt, try "startx"

after entering 'startx' this is what I get:

"xauth: creating new authority file /root/.serverauth.6604


Fatal server error:
Server is already active for display 0
If this server is no longer running, remove /tmp/.X0-lock
and start again."

My desktop now turned to black wallpaper also I cannot right click on the desktop. My OS is CentOS Gnome GUI.

First you have to kill the current gnome-session. The xkill command terminates the graphic objects but not the parent process that created them. Switch to a virtual console, e.g. Alt-Ctrl-1, login and do:
then logout and switch again to the graphic console Alt-Ctrl-7. You should see the login page again.

Thanks COLUCIX. It is now working!

I have one more problem. I cannot access any websites now before I can. Connection Timeout!
All my configuration are correct but I cannot access the web. Why is this?

I don't know. What does make you to suspect the problem is related to the xkill of the desktop? Maybe did you connect using a desktop (GUI) application which has been killed as well? Which kind of connection do you have (LAN, DSL, wireless, ...)?

LAN connection in our office (static IP). not related to xkill. After the blackout then I power on again and boom I have no internet access.

Config.

Static IP - Good
Gateway - Good
DNS Primary and secondary - Good
connected to domain

You shouldn't be running Xorg and browsing the 'net as root user.


As for your connection problems can you access LAN servers and services? Can you (tcp!)traceroute known sites?
