我的朋友有一台带有混合显卡（corei5 和 geforce920m）的华硕 x555UJ 笔记本。我们将 debian jessie 与 gnome 和 bumblebee 放在上面（https://www.unixmen.com/how-to-make-nvidia-optimus-technology-work-properly-on-debian/）。我们有问题。
问题1：全新安装后只有1024x768，即使在bumblebee安装后也没有改变。
问题 2：bumlebee 似乎可以工作，但是当它更改为 nvidia 卡时，它似乎使 libGL.so.1 崩溃（尝试使用 glxgears）。我们从 jessie-backport 安装了 bumblebee 和 nvidia，因为需要来自 backport 的 nvidia-driver 来支持 920m。这是 inxi 输出：

# To get the BusID prop, run `lspci | egrep 'VGA|3D'` and input the data

# This Setting may be needed in some platforms with more than one
# nvidia card, which may confuse the proprietary driver (e.g.,
# trying to take ownership of the wrong device). Also needed on Ubuntu 13.04.

任何帮助，将不胜感激！
谢谢！

答案1
您是否尝试过使用 nouveau 来使用 bumblebee（您是否确定 920m 的反向端口驱动程序 - 我确定我的 820m 可以与当前的驱动程序一起使用 - 我正在使用拉伸驱动程序），而且在使用 primusrun 时我得到了奇怪的结果，最好尝试 optirun ，但我不认为这能解决问题。
因为恕我直言：问题是这样的：
您尚未使用正确的 PCI BusID 配置 /etc/bumblebee/xorg.conf.nvidia（或 nouveau）。
只需执行 alspci |grep -i 3D即可获取正确的 PCI BusID（您的卡不在 01:00:00 上）
如果它不能修复它。尽快回到这里。
