我有一台配备 Intel HD4000 和 nVidia Quadro K2000M 的笔记本电脑。今天早上我刚刚在笔记本电脑上重新安装了 Archlinux，所以这是全新安装。
我这样驱动图形：
yaourt -S xf86-video-intel intel-dri bumblebee nvidia
我启用了bumblebeed，甚至安装了bbswitch，但仍然出现该错误：
skypers@ark ~ % optirun glxspheres
[ 815.104395] [ERROR]Cannot access secondary GPU - error: [XORG] (EE) NVIDIA(0): Failed to initialize the NVIDIA GPU at PCI:1:0:0. Please
[ 815.104447] [ERROR]Aborting because fallback start is disabled.
以下是一些信息：
skypers@ark ~ % dmesg | tail

这Xorg.8日志文件。 任何想法 ？
