i've Asus Laptop A43SM the specifications can be seen here.

I am trying to install Ubuntu 12.04 LTS on my laptop, but something wrong is happening. When I boot up Ubuntu on this laptop the first screen Ubuntu loader shows up, but then it freezes; I can't do anything but push the power button.

I've tried to use a usb drive and a CD but that doesn't help.

Anyone can tell me how to install Ubuntu ?

My first question would be: What is displayed on the screen when the computer freezes? Second would be: Do you have any other bootable devices installed in the laptop? – user60597 May 5 '12 at 13:12

When it starts booting press esc to stop it for a while, and then press F6 to turn on nomodoset

I have the same laptop as you and it works fine.
