我尝试通过在 Manjaro i3 中设置此内核参数来启用 DRM：
nvidia_drm.modeset=1
但之后系统拒绝启动 lightDM，因为出现以下 Xorg 错误：
failed to create screen resources
经过一番挖掘后，我在内核日志中发现了以下消息，其中提到了 noveau 驱动程序失败，即使我尚未安装 noveau 驱动程序。那么有人能理解这一点吗？

答案1
我想我终于想通了。至少autorandr现在终于检测到外部屏幕的插入，这是我想要启用drm的主要原因。
我关注了下面的文章 https://vfbsilva.medium.com/howto-set-up-prime-with-nvidia-proprietary-driver-c647e3597447
第1步：卸载大黄蜂
步骤 2：将 /etc/X11/xorg.conf.d/90-mhwd.conf 更改为：
Section "Module"
Load "modesetting"
EndSection
Section "Device"
Identifier "nvidia"
Driver "nvidia"
BusID "PCI:1:0:0"
Option "AllowEmptyInitialConfiguration"
EndSection
步骤 3 将 /etc/modprobe.d/mhwd-gpu.conf 更改为
##
## Generated by mhwd - Manjaro Hardware Detection
##
blacklist nouveau
#blacklist ttm
#blacklist drm_kms_helper
#blacklist drm
options nvidia "NVreg_DynamicPowerManagement=0x02"
blacklist nvidiafb
blacklist rivafb
options nvidia_drm modeset=1
步骤4
创建此文件（/usr/local/bin/optimus.sh）
#!/bin/sh
xrandr --setprovideroutputsource modesetting NVIDIA-0
xrandr --auto
使其可执行
chmod a+rx /usr/local/bin/optimus.sh
编辑 /etc/lightdm/lightdm.conf 并设置（如果您使用其他 dm，请查看文章）
display-setup-script=/usr/local/bin/optimus
