I did:

sudo apt-get install vnc4server



But VNC viewer at a Windows computer could not access the Ubuntu.

Then, I did:

sudo apt-get install gnome-core

But still no access.

Ubuntu already has a VNC server called vino. Vino is pre-installed.

If you run


you will get a dialog box to help you configure the VNC server, and even make your computer accessible for VNC from the Internet (if you wish to).

I recommend removing the packages you installed and use vino.

In addition, the pre-installed VNC client for Ubuntu is remmina.

Thanks, will do. How do I safely remove (uninstall) vnc4server and gnome-core? – user1689961 Oct 9 '12 at 15:10
You can remove them with sudo apt-get remove ..... Since you installed them, they should also uninstall as well. – user4124 Oct 16 '12 at 20:16
vino works great. Just one problem: I have to log in physically at the Linux Ubuntu computer before I remote into it from another computer, otherwise the VNC fails. Any solution? – user1689961 Oct 18 '12 at 16:56
