http://bugs.sabayon.org/show_bug.cgi?id=2210 ). It is still suboptimal of course couse an Xorg restart is needed, but if GPU hotplugging will become reality i strongly hope this kind of setup (intel IGP with open source driver + AMD/NVIDIA GC with proprietary driver) can do the switch at runtime.
From a personal point of view i'm not intrested in this kind of switching, i don't think it is a win. You spend more money (you buy 2 GC), you spend more power (you have two GC powered on, even if one is in a very low power state it still drains power), but of course i might be wrong. I have no problem buying a pc with hybrid graphics, but it must work in the way i said before on linux. I use linux for work and for my personal use as my main OS. If the hardware doesn't work or just half works it is useless or at least wasted money in point of view. I'm happy seeing AMD working on this, at least they are trying. I hear you saying "buy a pc with just an intel IGP", and i do for work. But for personal use i fell limited with intel only couse the power is a bit low. I really hope intel will reach the power of, let's say, the radeon HD 6550D (the one in the A8 AMD processors).
Thank you for your Open Source / free software work intel
