At the moment ATI Radeon HD6470 hasn't working proprietary driver. Open source driver works not well too: the card heats and cooler works very loud and notebook becomes hot. I would like to use integrated Intel's video card until this problem be solved, but I don't know how to switch to it and if it will work well with external monitor through VGA port.


my case: Thinkpad T500: ATI HD3650 -> Intel
I think I did similar operation just minutes ago. First and foremost - simply switching option in the BIOS to 'Integrated' resulted in Ubuntu booting into command line only, without desktop.
I did the following to solve my problem (general outline):

  1. Changed the BIOS display setting to 'Integrated' and booted into command line
  2. Uninstalled ATI drivers (proprietary) as per http://wiki.cchtml.com/index.php/Ubuntu_Oneiric_Installation_Guide#Removing_Catalyst.2Ffglrx
  3. Rebooted

If you have not yet resolved your problems you could try the solution outlined here by user Nick Andrik. This is the only thing that has worked for me after 6 months of searching and trying all sorts of solutions.

"For those who have hybrid systems (ATI/intel) and fglrx has stopped working in 12.10, then the problem might be like the one described here (fglrx incompatibility with the recent version of the intel driver): https://bugs.launchpad.net/ubuntu/+source/fglrx-installer-updates/+bug/1068404

What I would suggest would be

Remove all the fglrx* packages:

sudo apt-get purge fglrx*

Add my PPA in your repositories list:

sudo add-apt-repository ppa:andrikos

Update your package information:

sudo apt-get update

Update the fglrx and intel drivers:

sudo apt-get install fglrx xserver-xorg-video-intel

Don't forget to enable the fglrx driver

sudo aticonfig --initial --force"
