A few days ago I uninstalled Windows 7 & installed Ubuntu 12.04 LTS on my laptop (MSI CX620). No problems occurred in installation process. My laptop contains two graphic controllers
1) ATI Radeon HD5470.
2) Integrate chipset (Intel Core i3-330M).


  • System is running very slow
  • Not able to run Unity3d only 2d
  • Laptop becomes very hot in short period of time (1.5 hours, 100C)

What I think is wrong: Only integrated chipset is used, more powerful ATI Radeon is not recognized and not used.

Can somebody help me determine the problem. I'm not a very experienced linux user. Attached some information that might help:

Output sudo lshw:

Pic System details graphics:

Thanks in advance!

Here is an answer about installing graphics card drivers. – Seth Dec 8 '12 at 17:47
@iSeth You must be careful what you are pointing to and what the user have. The user has a dual graphics card and dual graphics aren't same as your normal driver installation. He can't install ATI drivers because it isn't recognized/used properly because of a hybrid system. Please see this. The answer is pretty old. I am not an AMD user, so don't know the latest development. @ Dennett please try to find out in BIOS whether you can disble intel/integrated graphics card – Web-E Dec 8 '12 at 19:45
@Web-E Oh, I didn't know there was that big of a difference, thanks for pointing that out. – Seth Dec 8 '12 at 19:55
