NVIDIA Optimus without bumblebee

已有 2825 次阅读 2015-11-26 23:28 |系统分类:科研笔记

Although bumblebee under Linux gives people lots of convenience in switching dedicated GPU to integrated ones, it still causes plenty of problems such as many software cannot detect the GPU correctly. NVIDIA Optimus, which only use the dedicated Nivida GPU by default for all program, seems to solve this issue.


Here are some steps showing how to configure Nivida optimus without Blumblebee:

Be sure:

* You are running OpenSUSE LEAP 42.1, 13.2 or 13.1

* You don't have bumblebee installed


1)install nvidia drivers using http://opensuse-community.org/nvidia.ymp

2)Download necessary tools:https://drive.google.com/file/d/0B-XzV1WxKN20Z3h2WFIxbWlEc3M/view?pli=1

Put the content of this package somewhere


3)Added the following lines

if [ -f /etc/X11/xinit/xinitrc.d/prime-offload.sh ];

then

. /etc/X11/xinit/xinitrc.d/prime-offload.sh

fi


To /etc/X11/xdm/Xsetup


after the line

". /etc/sysconfig/displaymanager"


4) Edit xorg.conf provided by this package to set the right PCI BusID for your nvidia card  (find it by `lspci|grep NVIDIA`), mine was 02:00.0, yours is probably something else. Edit the line in xorg.conf:BusID "PCI:2:0:0"


5)Run "bash primeselect.sh nvidia" as root. Log out and login again, hopefully you are using nvidia GPU. To switch back to intel GPU run "bash prime-select.sh intel"
