本子：MSI GE60 20C-051XCN
配置：
CPU： i7 4700MQ
显卡：GT750M+HD4600
内核：3.10.9（因为默认的内核驱动不了我的有线网卡）
方法1：改/sys/kernel/debug/vgaswitcheroo/switch，不过我的ubuntu没这个文件，连/sys/kernel/debug/vgaswitcheroo都没有（用3.8的内核也是如此）
代码： 全选
wangchaoran@azurepointer:~$ sudo ls /sys/kernel/debug/

问题：
1.现在希望bumblebee能在我的本子上正常运行，可以降点温，提高点能源利用效率，怎样解决装bumblebee造成的以上问题？
2.如果真的关不了独显，干脆就只用独显，反正对于游戏本，续航力都是浮云，干脆不关了，直接上N卡闭源驱动，不过看到有人说，双显卡本（独显为N卡）直接装N卡闭源驱动会导致X不能正常运行，是否对？有什么办法解决？
PS：
1.我的独显在lspci结果中被称为3D controller，而不是VGA compatible controller。
2.在sys里我找到了一个似乎与显卡电源有关的文件/sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/power/control（0000:01:00.0为独显的物理地址，0000:00:01.0为 Haswell PCI Express x16 Controller的物理地址），里面的默认值为on，可用 echo auto|sudo tee /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/power/control 改为auto，但改成off就显示参数错误，不能改成off。
3.我的bios无关显卡的选项。
4.贴一下lspci的结果
