my laptop has a ATI Mobility Radeon HD 5650, and I've tried many ways to install the drivers but nothing has worked for me, how can I do it?

Also, I'm not sure why but when I put 'lspci -vvnn | grep VGA' it showes me this:

VGA compatible controller [0300]: Advanced Micro Devices [AMD] nee ATI 
 RS880M [Mobility Radeon HD 4225/4250] [1002:9712] (prog-if 00 [VGA 
 controller])

VGA compatible controller [0300]: Advanced Micro Devices [AMD] nee ATI 
 Madison [Mobility Radeon HD 5650/5750 / 6550M] [1002:68c1] (prog-if 
 00 [VGA controller])

What does this mean?

Well, Radeon has officially dropped support for the HD series, so you'll have to use the open-source driver.

sudo apt-get install xserver-xorg-video-nouveau
sudo apt-get install --reinstall libgl1-mesa-glx libgl1-mesa-dri xserver-xorg-core
sudo dpkg-reconfigure xserver-xorg
sudo update-initramfs -u
sudo reboot #This will reboot your computer, so save any open files first.

That should get you going.

Credit and thanks to Bashing-om and QIII from the Ubuntu Forums for helping me get my card working.
This has been tested with a Radeon HD 4350.
