I'm using elementary os freya with UEFI mode. My laptop has two graphic cards (Intel 4400 and Nvidia 860 gtx) and it is getting so hot after using about 30-60 minutes.

I tried some ways to install bumblebee but in each way nvidia module not installed correctly and said :

modprobe: FATAL: Module bbswitch not found. [ 924.996622] [ERROR]Module bbswitch could not be loaded (timeout?) [ 924.996656] [WARN]No switching method available. The dedicated card will always be on. [ 924.997915] [ERROR]Module 'nvidia' is not found. 

Any ideas?
