[fish47 <fish47@xxxxxxx>]

Here is my info.
OS:Ubuntu 11.04
Kernel:2.6.38-10-generic (I check it out by using the "uname -r")
Laptop:Lenovo Idlepad V460
Graphic1:Intel GMA
Graphic2:G310m (I don't think it support the Optimus,because I bought this laptop in 2009 Jun)

Hi,recently I have tried the Ubuntu 11.04,that feels good.But what bother me is that I can't switch to my integrated graphic card.My discrete graphic card emits a lot of heat and draws a lot of energy.I have done a lot of research to figure it out,but it doesn't work.Whenever I watch the video on You-tube,I can feel the heat from my laptop fan.It must be the discrete graphic card is still working.

I have tried 3 methods.
1.acpi_call:It doesn't seem to work.
2.Bumblebee:The same to the above.
3.vgaswitcheroo:Can't find the file or directory.
If you want more specific info,please contact me,I will reply as soon as possible.

Thanks a lot.



Here is the methods I have used.
