I haven't personally tried installing ROOT on Ubuntu, but some googling turned up

It looks like, at the very least, you should install libx11-dev.

I am on Lucid lynx ubuntu
to install the cern root oo language:
click (french version) on Applications/Logithèque ubuntu (under sound and video/science et ingenierie/physique and then on then on root.
Root will appear in Application/programming
Is it what you want?

Ubuntu should have apt or synaptic. From that CERN page I linked above,

Use "sudo apt-get install package" or use the graphical "Synaptic Package Manager" program.

You need administrator or sudo access to your computer to do this. If you don't know what that means you should talk to whoever maintains your computer.

If you do it the way I told you lib11-dev will be installed. I just verified it with synaptic

In english it is called "ubuntu software center" (logithèque ubuntu in french".

i have installed the package

name@ubuntu:~/Downloads$ sudo apt-get install libx11-dev

It seems that there is a problem on your 11.04 software center unlike on my lucid linx version.
