我在 HP 笔记本电脑上运行 Debian 8.0 64 位(Jessie,稳定版本)。我在安装显卡的专有 nVidia 驱动程序时遇到了困难
01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GF108M [GeForce GT 630M] [10de:0de9] (rev ff)
我按照 Debian Wiki 上的指南一步一步操作。由于我的显卡配有 nvidia optimus,所以需要 Bumblebee。到目前为止一切顺利,我认为我的机器上已经安装了所有正确的软件包。现在我必须启用 bumblebee。事实证明正确的命令是
sudo optirun nvidia-settings -c :8
因此,图形前端出现了,我保留了所有默认检查,只需将配置文件保存在 /etc/X11 文件夹中,即 xorg.conf。但在系统重新启动时,我得到了黑屏,x 无法启动,它说“未找到屏幕”。这是日志

我认为您的配置指向了错误的显示器编号(除非您有很多显示器)。您可以尝试以下操作:
sudo optirun nvidia-settings -c :0
