Marketing is either forward looking (how I can sell more widgets), or complementary to a customer (I need to meet this requirement for to help a customer sell more widgets). Note that as a supplier, the customer is really the OEM.
And OEMs have proven SEVERAL times, that the customer is nothing they care about either (glare displays for example).
So where in this list is the customer?
What can I do as customer tog et what I want? Buying AMD?

So you're going to have to convince the OEMs to work at getting things more straightened out.
As for not supporting Optimus, that was something of a poor decision on NVidia's part- even if I understand the motivations behind them choosing that. They're going with what the OEMs are asking for- the main reason we have drivers is the workstation market and Optimus isn't likely to be used in that space. So, no driver support for it for us.
All this means is more room for AMD to get it's act together on things- and take the market segment from them (and there IS one, it's just not on your OEM's radar...). I WAS going to get a new laptop with NVidia because of the stuff just largely working on Linux (AMD's proprietary drivers have in the past been iffy in varying areas...and rumors of issues with suspend on the mobile parts has me still thinking there's still a bit to be done...) - but if they're going to play that game, I might have to reconsider that decision.

Can anyone please tell the developers at ATi what CUSTOMERS want? And make sure, that the marketing guys are stuck in snow somewhere, so they don't disturbing the devs with useless things.

I'm always wondering why this stuff can't be integrated in one GPU anyways. A simple gpu for the composited desktop and a real 3D unit which can be completely switched off. Or something more integrated: why can't maybe 98% of those processing "cores" be disabled on low workload. There should be a lower idle consumption be possible than AMD's current 5xx0 series has (>15W).
However, with IGPs being integrated into CPUs right as we speak, the future might look quite different. The output signal could always be routed through the IGP (so no display hardware on the dedicated GPU) and the extra GPU could only be fired up when the load becomes too heavy for the IGP. Something similar to the Voodoo2-era 3d accelerator add-on cards, in fact.

If dual GPU solutions become widespread in the future, I can imagine this coming to the open-source stack at some point. From a previous discussion it seems that X isn't really flexible enough for this right now, so it's mostly a matter of developer interested and manpower.
I also doubt this will come to open- and closed-source driver combinations (e.g. Intel + Nvidia) without very wide cooperation between all competitors (fat chance?) Time will tell.

I have no doubt that this, or something functionally equivalent, will be coming to linux at some point. Will nvidia implement it in their blob? I don't know and quite frankly, I don't give a rat's a$$.
To be honest, I really don't want any kind of magical hidden automatic switching... a manual mechanism + an optional daemon monitoring (to monitor for switch conditions and automatically switch it) and switching it will be enough. Let me be in control of it if I happen to want to be in control of it.
The other thing I expect in this nvidia implementation is that it will only work with nvidia/nvidia pairs. Likely as a result of driver constraints. Gallium3D with its softpipe should introduce the possibility of switching *live* between two DIFFERENT GPUs (since all GPUs, in the end, will have equivalent capabilities, albeit at vastly different levels of performance). And this, I think, will be really slick.

Originally posted by agd5f View PostThis sounds like new marketing on an existing concept. You can do this already if your system has two GPUs of the same capability level, you just need some extra smarts in the driver. It's basically power selective multi-gpu. Wire one to the displays and then render using the faster or slower one depending on what power mode you are in. When the other one is not in use, ramp it's clocks down.

I vote for PowerXpress on the DESKTOP with high-end graphic card and IGP. But I repeat myself (9 month ago):
And bridgman did not listen to me
