我的笔记本电脑同时配备独立显卡 (GTX 1050) 和集成显卡。lspci给出这个：

问题：xorg 无法识别 nvidia 卡。我使用的是 Ubuntu 19.04，但这似乎不是 ubuntu 特有的问题。glxinfo显示：

** Message: 21:01:38.481: PRIME: Requires offloading
** Message: 21:01:38.481: PRIME: is it supported? yes
xrandr --listproviders没有看到 nvidia 卡：
▶ xrandr --listproviders
Providers: number : 1
Provider 0: id: 0x48 cap: 0x9, Source Output, Sink Offload crtcs: 4 outputs: 5 associated providers: 0 name:Intel
我试着跟随这配置 xorg 和设置 PRIME 输出的指南，但它没有更改 的输出glxinfo，并且目前我没有使用任何额外的 xorg 配置。我已经通过以下方式启用了 drm /etc/modprobe.d/nvidia-drm.conf：
options nvidia_drm modeset=1
/etc/modules:
nvidia
nvidia_modeset
nvidia_uvm
nvidia_drm
顺便说一句，我的 xorg 日志：
