It was my graphics card drivers that were not updated.
I download the updated drivers on the graphics card website and install it directly in command line.

In my case, I bought a GeForce 6150 and I would install the last Ubuntu version (at the time : 10.04 LTS) on my PC.
When I started my PC, I had a white screen.
So, I have dl linux drivers on http://www.geforce.com/drivers, boot my PC into console command line instead of X and install the driver (I don't really remember the command that I used, but by google I find the command : jockey-text, ref : how-can-i-reconfigure-the-nvidia-proprietary-drivers-from-the-command-line
What graphical card do you use?

a) Did you boot your laptop with the Ubuntu Live CD before you installed it? It sounds like you didn't. Due to various weirdnesses with laptop hardware and Ubuntu incompatibilities the same, it really is worthwhile to test the Live CD first, and try several things with it.
b) Installing Ubuntu probably will not help with getting a RedHat certification, mainly because the package manager and other subtle differences make Ubuntu and RedHat administration somewhat different.
c) You probably would be better off install VirtualBox on your laptop and running a CentOS VM. But what are the specs of your laptop? Linux VMs run fine on my laptop, a 5-year old HP with an AMD dual core 1.8GHz proc and 4GB or RAM.
