Are you using the 32bit version or the 64bit version?
And have you installed the "RESTRICTED" display drives yet.
To find out Click Applications in the menu bar at the top (unless you've moved it ). Select Accessories->Terminal.
In the new command terminal type "uname -a" (dont type the quotes) this will then display some thing like this
Linux user-desktop 2.6.24-16-generic #1 SMP Thu Apr 10 13:23:42 UTC 2008 i686 GNU/Linux
The i686 bit means that you have the 32bit version of Ubuntu installed (the 64bit version displays x86_64)
If you have the 32bit version in the command terminal type
sudo apt-get install g++-3.3 libglu1-mesa-dev x11proto-core-dev x11proto-gl-dev x11proto-kb-dev libxxf86vm-dev libasound2-dev
This can be found here (

If it's the 64bit version of Ubuntu then it gets tricky.
I had to create a chroot environment and install a very minimal 32bit build environment so that every thing would work correctly. Instruction found here (

As for the "RESTRICTED" display drivers to initialize those in the menu bar at the top click System->Administration->Hardware Drivers and click the Enable check-box, then restart the computer.
