Install GPU on ArchLinux
前言, 之前比較坑的是, 在安裝了nvidia 跟 nvidia-utils 之后, 重啟就莫名其妙的黑屏了, 別慌, 這是xorg與nvidia驅動之間的沖突, 或者是配置問題, 先卸載原來與nvidia相關的package, reboot , 現在你就再一次進入到圖形化的世界里面了.
Add nouveau to blacklist
去除一些與nvidia沖突的組建, 添加到黑名單里面
sudo vim /etc/modprobe.d/nouveau_blacklist.conf
blacklist nouveau
more blacklist
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
去除原來的nvidia的設置
cd /etc/X11/
rm xorg.conf
Install Nvidia and bumblebee
Install Dependecy First
必須先安裝這個依賴
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
另外我好像也安裝了 nvidia-settings , nvidia-config 啥的.
將自己添加到bumblebee用戶組
這里scorpion是我的用戶名
sudo usermod -a -G bumblebee scorpion
啟用bumbleed
sudo systemctl enable bumblebeed
Error
[ERROR]Cannot access secondary GPU - error: Could not load GPU driver
[ERROR]Aborting because fallback start is disabled.
解決方案 配置bumblebee.conf

重啟 配置bios
Run as Root update nvidia config and restart kdm
su
nvidia-xconfig
# restart kde
systemctl restart sddm
