全程root用户运行, 本次的闭源驱动最新版是430
1、安装闭源驱动
$ pacman -S nvidia nvidia-utils nvidia-settings
2、查看n卡的BusID
$ lspci | egrep 'VGA|3D'出现如下格式：----------------------------------------------------------------------00:02.0 VGA compatible controller: Intel Corporation UHD Graphics 630 (Desktop)01:00.0 VGA compatible controller: NVIDIA Corporation GP107M [GeForce GTX 1050 Ti Mobile] (rev a1)
3、自动生成配置文件
$ nvidia-xconfig
4、启动脚本配置
LightDM
$ nano /etc/lightdm/display_setup.sh----------------------------------------------------------------------#!/bin/shxrandr --setprovideroutputsource modesetting NVIDIA-0xrandr --auto----------------------------------------------------------------------$ chmod +x /etc/lightdm/display_setup.sh$ nano /etc/lightdm/lightdm.conf----------------------------------------------------------------------[Seat:*]display-setup-script=/etc/lightdm/display_setup.sh----------------------------------------------------------------------
SDDM
$ nano /usr/share/sddm/scripts/Xsetup----------------------------------------------------------------------xrandr --setprovideroutputsource modesetting NVIDIA-0xrandr --auto
GDM
创建两个桌面文件/usr/share/gdm/greeter/autostart/optimus.desktop/etc/xdg/autostart/optimus.desktop----------------------------------------------------------------------[Desktop Entry]Type=ApplicationName=OptimusExec=sh -c "xrandr --setprovideroutputsource modesetting NVIDIA-0; xrandr --auto"NoDisplay=trueX-GNOME-Autostart-Phase=DisplayServer
5、修改配置文件
$ nano /etc/X11/xorg.conf----------------------------------------------------------------------Section "Module" #此部分可能没有，自行添加load "modesetting"EndSectionSection "Device"Identifier"Device0"Driver "nvidia"VendorName"NVIDIA Corporation"BusID"1:0:0" #此处填刚刚查询到的BusIDOption "AllowEmptyInitialConfiguration"EndSection
6、解决画面撕裂问题
$ nano /etc/mkinitcpio.conf----------------------------------------------------------------------MODULES=(nvidia nvidia_modeset nvidia_uvm nvidia_drm)----------------------------------------------------------------------$ nano /etc/default/grub# 此处必须是grub引导，其他引导自行百度----------------------------------------------------------------------GRUB_CMDLINE_LINUX_DEFAULT="quiet nvidia-drm.modeset=1"#此处加nvidia-drm.modeset=1参数----------------------------------------------------------------------$ grub-mkconfig -o /boot/grub/grub.cfg # 就算grub引导，配置文件也可能不在一个地方，请查看清楚
7、nvidia升级时自动更新initramfs
$ mkdir /etc/pacman.d/hooks$ nano /etc/pacman.d/hooks/nvidia.hook-----------------------------------------------------------------[Trigger]Operation=InstallOperation=UpgradeOperation=RemoveType=PackageTarget=nvidiaTarget=linux# Change the linux part above and in the Exec line if a different kernel is used[Action]Description=Update Nvidia module in initcpioDepends=mkinitcpioWhen=PostTransactionNeedsTargetsExec=/bin/sh -c 'while read -r trg; do case $trg in linux) exit 0; esac; done; /usr/bin/mkinitcpio -P'
