我有一台 Sager np8290 笔记本电脑，配备 NVidia geforce GTX 770m（optimus）。我目前正在尝试bumblebee使用 Ubuntu 13.04。经过所有这些混乱和全新系统安装，我相信我已经能够让 bumblebee 正常工作，因为我可以运行 optirun，glxspheres而且它运行良好。但我无法运行bbswitch。我知道主 Nvidia 卡一直在运行，因为计算机变得非常热，风扇一直在旋转。

我现在正在运行更新后的内核
$ uname -r
3.9.4-030904-generic
我不知道为什么我无法bbswitch运行。我想关闭 Nvidia 卡以防止它变得太热！
任何想法或其他解决方案的链接都将受到赞赏。
答案1
好吧，至少你并不孤单。
这里是 MSI GE40，配备 GTX 760M。完全相同的问题，optirun 运行良好，并且有效果，但我无法关闭独立显卡（而且它消耗了大部分电量）。没有 /proc/acpi/bbswitch - bbswitch 不喜欢加载：
[119624.055053] bbswitch：版本 0.7 [119624.055059] bbswitch：发现集成 VGA 设备 0000:00:02.0：\_SB_.PCI0.GFX0 [119624.055062] bbswitch：找不到 VGA 设备 0000:01:00.0 的 ACPI 句柄 [119624.055064] bbswitch：未找到独立 VGA 设备
如果我找到解决方案，我一定会回到这里......
编辑：我发现了这个帖子，
https://github.com/Bumblebee-Project/bbswitch/issues/65
这告诉我们这是内核 3.8.5-1 的一个内核错误。希望很快会再次发布一个可用的内核版本。如果您想编译自己的内核，请阅读该帖子，或者将内核恢复到 3.8.4。
答案2
我也遇到了同样的问题。使用的是 Ubuntu 12.04 LTS 和 3.8.0-31-generic 内核（Ubuntu 13.04 的内核）。我能够让 optirun 和 primusrun 都工作，但 bbswitch 在使用后不会自动关闭独立 GPU。
我最终通过安装最新的 v3.11 内核成功让 bbswitch 正常工作。请按照本页上的步骤操作：http://itsfoss.com/linux-kernel-3-11-install-in-ubuntu/
