Ubuntu: why is my ATI graphics driver not working?


i just installed ubuntu day ago and im total newb in this system. after installation and ubuntu update i found out in "System Info-"Graphics":



after that i found "Aditional Drivers" utility in "System Settings" and i found there 2 proprietary drivers:

  1. ATI/AMD proprietary FGLRX graphics driver (post-release updates)
  2. ATI/AMD proprietary FGLRX graphics driver

when i activate first, it shows me error and it wont install. when i activate second, installs fine and asks for restart and after i restart graphics are slow and choppy, and youtube vids are slower then when was with no driver. and "System Info-"Graphics" shows next:

Driver-VESA: RS780MN


My Graphics card is ATI Radeon HD 3200 My netbook is Lenovo x100e

*update i uninstalled ATI/AMD proprietary FGLRX graphics driver and manually installed driver i downloaded from oficiall ATI site and system's graphics are still choppy. I can opet ATI Catalyst Control Center, and it detect my graphics card, and everything looks fine but system is still choppy.


I have the same graphic card in my laptop, but I use the open source driver. It works fine, I am able to run Unity and 3D applications normally.

I'd recommend you to install the open source driver (xserver-xorg-video-radeon Install xserver-xorg-video-radeon - click on the image to install it).

According to the manual page, the package should support Radeon Mobility HD 3200.


What I did is to go to this page : http://support.amd.com/us/gpudownload/Pages/index.aspx Choose your graphic card. (If you are not quite sure, you can verify by typing lspci | egrep VGA in your terminal)

Then follow this instructions : https://help.ubuntu.com/community/BinaryDriverHowto/ATI#Manually_installing_Catalyst_12.3
