Ubuntu – How to install the ATI graphic card

atidriversradeon

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?

I recommend to install xserver-xorg-video-radeon, the driver works great in trusty

sudo apt-get install xserver-xorg-video-radeon

xserver-xorg-video-nouveau mentioned in this answer is a driver for NVIDIA.
