From what I learned new GPUs from NVIDIA are using the Optimus technology which does not support Linux, meaning that only the dedicated graphics on the system will be used in Linux. Does it still make sense to go for NVIDIA instead of ATI? No, the right way is to contact NVIDIA and pressure them to support Linux. Just sending a mail to customer support saying what you just wrote before is enough. Also, Eric suggest a smart way. But even if it works, you should bother NVIDIA so that in the future things will evolve in the right way. Many people did this several years ago, so at some point, NVIDIA started providing quality Linux drivers. In fact, people should bother NVIDIA so much so it is even possible for people outside of NVIDIA to support the Linux driver even when NVIDIA will no more be interested into supporting it. Eric Eric, Optimus is a technology for fast switching between the slow internal graphics unit and a fast, but power-hungry, NVidia chip. Unfortunately, it is currently only supported by Windows7. If the notebook's BIOS offers to permanently disable, or permanently enable, the NVidia graphics then, from the Linux view, this would be equivalent to a conventional notebook with slow/fast graphics. If it just defaults to one of those states then, using Linux, you are at the mercy of the decision of the BIOS developers. So I'd say: before you buy investigate what the BIOS offers.

Re: [ccp4bb] Graphics for notebook
Eric, if you want to use stereo on a notebook you have very limited options. I have stereo running using a Lenovo T61p with a Nvidia Quadro FX570M under XP, not tried Linux yet. Officially this card is not even supported by Nvidia for 3D application, but works anyway in conjunction with a docking station, which has a DVI adaptor. Don't go with a Quadro NV series, they did not work in our hands.

The Quadro FX 3700M in my Dell Precision 6400M notebook works great with stereo in Windows, no support for Linux yet though.

Re: [ccp4bb] Graphics for notebook
It's best to have dedicated NVIDIA (don't have much experience with ATI, but it is my understanding that they may be more difficult to configire sometimes). However, Intel on-board graphics has gotten much better recently (in fact, Intel releases drivers as open source (guess because they are not big players in video cards). I am not sure you'll actually notice any difference between NVIDIA and Intel integrated, since coot is not as demanding as the bleeding edge videogames for which high-speed graphics matters. I'd recommend to search various linux forums for information about the laptop you are considering - if it's a fairly new model, there are often issues you'll need to resolve to get it going. Ed.

Re: [ccp4bb] Graphics for notebook
Hi Eric, I wanted to know which type of graphics card is more suitable for a notebook which is going to be used for structural biology. Integrated or dedicated? ATI or NVIDIA? At the moment I have to choose between an integrated Intel HD Graphics or a dedicated NVIDIA NVS 3100M Graphics. Any suggestions are highly appreciated. These responses are in line with what I'd recommend. First, NVidia presently has the drivers with fewest number of PyMOL bugs (then ATI, then Intel) across all platforms. Their Linux support, has for years, outstripped the competition. Next, if you're doing anything graphics related, I'd highly suggest moving away from integrated boards. Last, the integrated mobile boards are the worst offenders--I'm looking at you Intel GM945!--so if you can help it, stay away from them.

Definitely NVidia or (maybe) ATI. NVidia's Linux support has usually been much better. The integrated graphics will probably be okay for rebuilding in Coot, but you won't get hardware antialiasing and as soon as you try to do something complex like PyMOL surfaces, you're going to wish you had a better computer. -Nat
Re: [ccp4bb] Graphics for notebook
NVIDIA NVS 3100M is an entry level card that mostly is designed with 'business applications' in mind - meaning that its rendering/polygon/3D engine is relatively weak compared to an average or even low-end modern desktop graphics cards. Nevertheless it is definitely a step up from an integrated card.

Re: [ccp4bb] Graphics for notebook
If using Linux, definitely a dedicated NVidia - their drivers are the best supported by far. There are also some issues right now with the drivers for some of the integrated Intel graphics cards, a bug with handling OpenGL applications which prevents O, Coot, and PyMOL from working properly, among others. If using Windows or Mac, anything will do but I would go with a dedicated card to keep the load off the CPU so it runs much smoother when moving. I've used discrete NVidia cards in all of my systems, always worked without any problems. Stuart ___ Stuart Endo-Streeter, Ph.D Dept.
