I have HP ProBook 4530s laptop with AMD Radeon HD 6490M graphics card. After installing Ubuntu it runs on Intel Sandybridge graphics. The Ubuntu community page says: "By default Ubuntu will use the open source ATI or Radeon driver for cards manufactured by AMD/ATI." I already have installed the required driver packages: xserver-xorg-video-ati xserver-xorg-video-radeon xserver-xorg-video-vesa xserver-xorg-video-intel xserver-xorg-video-all, but it uses Intel driver anyway. When I'm uninstalling the Intel driver (xserver-xorg-video-intel) and rebooting, Radeon graphics works, it uses Gallium driver, but only 2D session loads. This page says: "No configuration is necessary for ATI driver in the modern versions of Ubuntu." and I'm using Ubuntu 12.04. What's wrong? P.S. I don't want the proprietary FGLRX driver, it's really buggy on my system.

  • Do you by chance have hybrid graphics? – Uri Herrera Sep 8 '12 at 18:28
  • Yes, I have hybrid graphics. – Giorgi Gzirishvili Sep 8 '12 at 19:53
  • Can you disable the Intel GPU from the BIOS? – Uri Herrera Sep 8 '12 at 20:01
  • Unfortunately I can't. – Giorgi Gzirishvili Sep 8 '12 at 20:02

Have you tried this?

sudo apt-get remove --purge xorg-driver-fglrx fglrx*  
sudo apt-get install --reinstall libgl1-mesa-glx libgl1-mesa-dri fglrx-modaliases  
sudo dpkg-reconfigure xserver-xorg

sudo apt-get install --reinstall xserver-xorg-core

This should make your system use the opensource driver. It worked for me. I have a different computer but it has a Radeon HD 4000 series
