I've seen a lot of people in this situation, but every time the variables differ and so does the solution for it.

I think I have everything installed correctly. I have Nvidia GeForce 540M with Bumblebee drivers installed.

What happens is, every two times when Ubuntu starts it tells me it is running in low-end graphics mode. I say OK and it crashes at the next window. I just restart and it starts normally.

I've made:

lspci -nn | grep '\[030[02]\]:

and the answer was:

00:02.0 VGA compatible controller [0300]: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0116] (rev 09)
01:00.0 3D controller [0302]: NVIDIA Corporation GF108 [GeForce GT 540M] [10de:0df4] (rev ff)

At the interface which have "low graphics mode", press Ctrl+Alt+F1. After login, input: 

sudo service lightdm restart

and it will go in to x window. Input: 

sudo apt-get install gdm

and choose gdm later. This method is using gdm to replace lightdm. Reboot.
