在无法让 Bumblebee 与我的外部显示器一起工作后（xrandr 没有“看到”它），我重新安装了 Debian。我在 Nvidia Dev Forum 上（没有找到 atm）建议安装 384。通过这个设置，我让 nvidia 在我的外部显示器上使用 X。我使用 gdm3 作为显示管理器。在没有我的显示器的情况下启动会导致 X 崩溃并出现 (EE) 未找到屏幕。
WaylandEnable=false通过注释in来反转此设置/etc/gdm3/daemon.conf将允许我在笔记本电脑显示器上启动 Gnome(Wayland)。现在从 wayland 开始会导致启动时出现循环。
如何让 Nvidia 识别我的 2 个屏幕？

新的 xorg.conf 带有 --enable-all-gpus --separate-x-screens ，与旧的没有什么不同的体验。
