Generic you do not need to configure anything for Intel-videocards. Also to know more in detail what kind of videoadapters yours are (model, generation). From what you have shown now this seems to be a system using Nvidia Optimus, which is questionable "good" - more bad. The reasoning why I write this: Depending especially on the generation of your graphicscard Nouveau does not even provide any support - therefore the linked feature matrix in the corresponding wiki-article.

Personal I would not use any Nvidia graphicsadapter, because either you have no really good or even no support (depending on the generation as stated). You should look for your BIOS- / UEFI-settings and when possible deactivate the Nvidia-adapter complete just leaving the integrated graphicsadapter working (Intel UHD Graphics).

Neither AMD nor NVidia are really good for anything: Either they don't support acceleration (without firmware-blobs, AMD) or they have not enough power through implementation of free, libre drivers (not the fault of nouveau that Nvidia is not providing proper documentation and reject help). So in the end: Integrated graphiccards from Intel. Sorry, but that's the honest answer.

I have myself a D16 besides its power-consumption (I would remember that this is for real a midrange-server-system): I have used an Nvidia 770. But I have only used this for terminal as this machine did run virtual machines and services on it. But its power-consumption brought me to the decision to deactivate it again. That's a personal story for sure, so everyone decides different. But energy is critical combined with our environment, so we need to look after it.

Please let us not do this kind of argumentation: Meaning to raise some numbers we have heard or read just "somewhere on the internet" and using that for a convinient type of argumentation. Sure you do not mean it exactly that way. But to state: It did not mean anything for me what the tankers are doing in relation towards the D16 I had deactivated. It means surely for me what they are all doing, but "Coca Cola" and "Tesla" have also customers using their products, so they do not stand alone. We are all responsible and it is just too easy statng that "others are doing more bad".

So you see that your argumentation is kind single-sided going just in one direction. If I had made you angry or you feel provocated, that was not my intention. But please do not state just some numbers as I know for sure that it is not 0.01% maximum. Or do you not count ASICs for cryptocurrency-mining, streaming, cloud-services- and computing? They are done via PC (per defintion "Personal Computers"), so they all count in and this is not that kind of percentage number you have state. There will be an article coming about why Hyperbola is declining cryptocurrencies and there you can read for example more about some of those topics. And when people are buying literally obsolete hardware (ASICs) being in that moment useless when a new model is there, it is a bunch of e-waste done by intention. And that is surely a big issue, meaning the percentage of 0,01% is not fitting for sure.

Yes, in relation to others named: The number is less. But do we really want to name responsibilities? Then we need to make the same also for our position. That's what Hyperbola is about. So if you want to create a D16-based system I just want to state that you may be frustrated about the Nvidia-component depending for what purpose this computer should be. And it is my responsibility also to share my experiences: For server-implementation? Then I can give you alternatives. For desktop and gaming? Your T440p should be very good for that, including the energy-consumption. As I have said: I have used the D16-system as server (its intention) and terminal only. But the energy-consumption was nevertheless with 550W too high for me when this system should run longer, even 48hours around a week.

The comparison is just: Taking the consumption of a mobile computer running and tower PC or even midrange-server like the D16-boards are for that purpose. Those energy-consumption is way more different besides their noise also. So you should know that for sure. If you want to do that as I have done it also (https://forums.hyperbola.info/viewtopic.php?id=384), please make your experiences on your own. No problem, but in relation to our current times perhaps it is good to look more close together.

And I better add again: I surely care very much about tankers on the oceans and I care also about companies, corporations doing their nonsense around and polluting our environment. But I care also about all the people not caring about this as the named actors before can only do this because they are kept in the position to do that. For me speaking I take therefore conclusions for my responisbilities then when I look out to do something. As that is the only point of language and action. If I can motivate others? Cool. But again: If we use this kind of argumentation you have now used, this does not work.

Well, we can surely debate this in forum. But then in another part of it. I would have interest and I bet you have the same as far I can see. But the issue stays as said and you have noted: It is the human ignorance and the opposite our possibility to have empathy for other beings same. So I close into your point of view. But I also guess: We would have need to make it not so complex so others would go in. Proposal: Let's finish first the article in the wiki and then we look again. As far to state: You seem to have same stance as I have on this.

About the 550W: This is meant the power-consumption under high loads. The D16 is a midrange-server-board and therefore it is high performance in many ways and possible scenarios. I have used the D16 for virtualization. So you can run surely many virtualized environments on one machine. But when there are database-servers under high load and application-servers doing theirs, web-server included, this gets a bit harsh for energy-consumption.

Running a D16-server with Libreboot was too much in perspective of energy-conumption and costs. So I have deactivated that system and migrated all parts on way more smaller systems. https://forums.hyperbola.info/viewtopic.php?id=143

When you get on standby times you would surely have a different consumption. But beware nevertheless: The selected graphicscard-generation is already having in case also the need to be connected to the power adapter of the computer. Also: You don't have the choice for smaller power adapter. I have tried with 400W and even smaller. The mainboard does not even bootup in those cases. So at minimum you would have the need for 450 or up to 500W. And when all components get under load (gaming and / or rendering load) you will have sure a big consumption.

On power consumption, if your card can drive 720p movies, it should be good enough for basic daily usage. 1080p as a graphics artists, maybe.  Also, it's a pity people doesn't know low power services such as Gopher, Gemini, IRC, XMPP... against the power sucking monsters of web based "crapware".  Even propietary software got into this madness. Back in the day a Pentium 3 could watch street view panoramas form Google. Equirectangular panoramas are not magic: My Atom can play these freely with libquicktime and lqtplay from that package. I guess that by using Curl and a custom equirectangular viewer, no propietary software would be needed at all, a propietary software which needs a Core Duo computer to a task, again, a Pentium 2 or a Pentium 3 could do in 2001.  It shoudln't bee too difficult, the most difficult task would be to seek for an sxiv/feh like viewer for these images and a tiny tcl/tk wrapper showing the panorama window inside with a URL box and some TLS calls with tcllib.
