#nvidia optimus

... but on a system, which is also using bumblebee because you’re too effing lazy (at least I was) to use a fresh install.

노트북에서 그래픽코어는 매우 중요한 차이를 만들어 냅니다. 고사양 3D 게임을 노트북으로 즐길수 있는가 없는가에 대한 문제가 이 그래픽코어의 종류에 따라서 차이가 발생하기 때문입니다.

여러분들도 기본적으로 인텔 HD 그래픽스는 CPU에 내장된 그래픽코어이며 NVIDIA 나 AMD등의 별도 외장 그래픽코어가 장착된 모델들이 구분된다는 것을 알고 계시리라 생각됩니다.

오늘은 이러한 외장 그래픽코어중 엔비디아(NVIDIA)사의 그래픽코어 시리즈에 적용되는 기술인 옵티머스(Optimus) 테크놀러지 기술에 관하여 소개해드리고자 합니다.

3D 그래픽처리가 많아지면 배터리 소모량도 증가

노트북은 일반 데스크탑PC와 다르게 배터리에 의한 전원공급을 받게 되어 있습니다. 어답터를 연결하지 않는다면 배터리용량만큼의…

I'm going to log how I got Civilization 5 purchased through Steam to run on Linux.

After trying various configurations and packages, I settled with installing

$ sudo apt-get install nvidia-drivers primus bumblebee

This gave me a bumblebeed daemon and a program called optirun which can be used to start graphical programs.

You can test the bumblebeed daemon using these commands:

$ sudo apt-get install mesa-utils $ glxinfo |grep vendor server glx vendor string: SGI client glx vendor string: Mesa Project and SGI OpenGL vendor string: Intel Open Source Technology Center $ optirun glxinfo |grep vendor server glx vendor string: NVIDIA Corporation client glx vendor string: primus OpenGL vendor string: NVIDIA Corporation

Now simply run

$ optirun steam

If working with an Nvidia graphics card or chipset wasn't difficult enough on Linux (thanks for the horrible support, Nvidia,) there is the issue of working with Nvidia Optimus.

If you're one of the people with a laptop touting the merits of Nvidia Optimus with a shiny sticker to prove it on the armrest, and haven't heard of the Bumble-bee Project, you don't know what you're missing!

Or maybe you DID hear about it, like I did a year or so ago. But then you tried to further look into it and the fact that it somewhere down the road the project got divided into another side project, and the documentation wasn't so great, and the installation itself wasn't exactly an easy thing, you just decided it wasn't worth the time.

Well, it's time to reconsider the Bumble-bee Project, because with their latest release (3.0) things have never been as easy.

Not only does Bumblebee give you the option of configuring and switching between your Intel and Nvidia chipset, it also installs the Nvidia drivers for you. 

I'm not going to waste anymore time, let's get our hands dirty, shall we?

Add the repository

sudo add-apt-repository ppa:bumblebee/stable

Update

sudo apt-get update

Install Bumblebee and Nvidia drivers
