Integrated and Passive GPU

Postby aeternal on Tue May 03, 2011 12:05 pm

Few time ago I heard about some problems but I didn't care that much. Since I'm going to buy a notebook soon, right now I start caring :P

The question is simple, the notebook will have an integrated GPU (the one you can find into Sandy Bridge, it's called h3000 as far as I know) and also a dedicated GPU (nVidia). As far as I know there are not physical switches, therefore I guess that the dedicated one starts computing when the integrated one is not enough.
So, few time ago I heard that there were some problems because you couldn't stop one of the two and they were both running. And as you may imagine, battery goes down down down :)

Do you know the current situation? I won't play games in Linux, however I may watch a full HD movie, therefore even the dedicated GPU may be needed. Is it possible to change between them in Mint?

Linux Mint is funded by ads and donations.

However in case I need both they are actually supported? So if I never need both I may change the BIOS settings, but if I don't change them the passive GPU will start only when the integrated can't handle the needs (like it should) or this feature isn't still working in Mint/Debian ?

Not depend on the distro.Most laptops have compatibility problems with acpi and hardware in all linux world, is rare to see one of them 100% compatible.
Because of this, it has created a compatibility list, see:
