I have a AMD Radeon HD6630 2GB card, and the processor is: Intel Core
i5-2430M Processor

When I look in lspci I see the following:

matt at mariachi:~$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core
Processor Family Integrated Graphics Controller (rev 09)
01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI
Whistler [AMD Radeon HD 6600M Series] (rev ff)

Then in "Settings > Details >  Graphics" I see:

Driver: Intel Sandybridge Mobile
Experience: standard

which suggests that it's seeing the inbuilt chip ok...  I think!?

You could also look into /var/log/Xorg.0.log and see what X is doing on

Nothing obvious in there.. but I will check next time immediately after

One thing I like to try is to stop gdm/lightdm whatever, and then run

Good suggestion!  thanks... Will try it next boot.

Thanks Philip!
