GT 720M (Optimus) 显示驱动程序设置 - Crunchbang Waldorf/Debian Wheezy

在安装 Crunchbang 11（基于 Debian Wheezy）并首次启动后，由于 Xorg 无法启动，我被强制进入 shell Fatal server error: no screens found。

我的笔记本电脑有基于 Optimus 的 GT 720M。Nouveau 在安装过程中自动安装，并且似乎在某种程度上占用了 GPU：

我尝试安装 bumblebee 和 primus，但似乎都没有帮助。Optirun 似乎无法识别第二个 GPU（尽管这可能是由于 Xorg 没有运行）：

~$ optirun glxgears
[  625.400763] [ERROR]Cannot access secondary GPU - error: [XORG] (EE) Failed to load module "mouse" (module does not exist, 0)

[  625.400809] [ERROR]Aborting because fallback start is disabled.

值得注意的是，它是一个基于 UEFI 的系统。

答案1

您最好使用 nvidia 专有驱动程序和 primus，刚刚在以 UEFI 模式启动的 Lenovo B570e 上检查了基于 ALT Linux 的 LiveCD。

顺便说一句，配备 Optimus 的较新型笔记本电脑往往仅将视频输出连接到英特尔 GPU。
