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


For software switcher you may try the switcheroo https://help.ubuntu.com/community/HybridGraphics

There is no setting in my BIOS to manipulate graphics. –  VitalyP Jan 25 '12 at 20:26

I can't help you then. I've never fiddled with software methods for switching graphics. switcheroo is the only hint I have for you help.ubuntu.com/community/HybridGraphics –  Bucic Jan 25 '12 at 21:28
    
Thanks. I use it at the moment to swithc Radeon card off and stay with integrated one. But for some reason my laptop is still heating :( –  VitalyP Jan 25 '12 at 22:07
    
Heating is a whole another story. A really nasty one unfortunatelly askubuntu.com/questions/72121/… You may start here ubuntuforums.org/showthread.php?t=1822629&page=23 –  Bucic Jan 25 '12 at 22:14

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"
