I've been a Gentoo user for a long time, but I switched to Arch a few years ago (that's what everybody is using at work, so...). But I just purchased a brand new Sony Vaio SA, and I decided to try Sabayon, that I discovered on distrowatch, as it seemed great! So far, so good. ^^
But now that it's installed, I have a few questions that are hardware-related. Those new Vaio come with an interesting feature: the possibility to switch, during runtime, between a dedicated ati card and the default intel chipset. The point of it is of course to be able to work with a low-consuming chip and to switch to the powerful one only when needed. Currently, my Sabayon install uses the radeon driver (fglrx driver makes X segfault), so I suppose it uses the dedicated 6630M radeon card at all times, whatever the switch says. This is backed up by the fact it is way hotter than under Windows and by the fact that battery life is half what it is under Windows.
I currently have absolutely no clue about how to get that working, and I can't find any relevant documentation anywhere, mostly (I suppose) because that laptop is brand new. Also, I'm not used to linux on laptops and I'm therefore a noob as far as acpi or temperature questions go. So I'd be happy to have a few pointers about how to start: where can I learn more about that feature, if you konw a tutorial that explains how to get it working... any vaio sa related documentation would be appreciated.
Thanks in advance!(and sorry for my English).
