Install GPU on ArchLinux

前言, 之前比较坑的是, 在安装了nvidia 跟 nvidia-utils 之后, 重启就莫名其妙的黑屏了, 别慌, 这是xorg与nvidia驱动之间的冲突, 或者是配置问题, 先卸载原来与nvidia相关的package, reboot , 现在你就再一次进入到图形化的世界里面了.

Add nouveau to blacklist

去除一些与nvidia冲突的组建, 添加到黑名单里面

sudo vim /etc/modprobe.d/nouveau_blacklist.conf

blacklist nouveau

more blacklist

reference from https://askubuntu.com/questions/481414/install-nvidia-driver-instead-nouveauhttps://askubuntu.com/questions/481414/install-nvidia-driver-instead-nouveau

blacklist nouveau
blacklist lbm-nouveau
options nouveau modeset=0
alias nouveau off
alias lbm-nouveau off

Remove xorg.conf or configure in xorg.conf.d

去除原来的nvidia的设置

cd /etc/X11/
rm xorg.conf

Install Nvidia and bumblebee

Install Dependecy First

必须先安装这个依赖

yaourt -S mesa

yaourt -S xf86-input-mouse
yaourt -S xf86-input-evdev
yaourt -S xf86-input-keyboard

Install Nvidia and bumblebee

yaourt -S nvidia bumblebee

另外我好像也安装了 nvidia-settings , nvidia-config 啥的.

将自己添加到bumblebee用户组

这里scorpion是我的用户名

sudo usermod -a -G bumblebee scorpion

启用bumbleed

sudo systemctl enable bumblebeed

Error

[ERROR]Cannot access secondary GPU - error: Could not load GPU driver
[ERROR]Aborting because fallback start is disabled.

解决方案 配置bumblebee.conf

重启 配置bios

Run as Root update nvidia config and restart kdm

su

nvidia-xconfig

# restart kde
systemctl restart sddm
