NVIDIA dual-graphics card

Step 1:
Sudo Update-pciids # It is very important to update the video card information. Otherwise, an error may be identified.
Lspci-v | grep-I VGA # view the video card

My video card information is as follows:
00:02. 0 VGA compatible Controller: Intel Corporation 2nd generation core processor family integrated graphics controller (Rev 09) (prog-If 00 [VGA controller])
0:00. 0 VGA compatible Controller: NVIDIA Corporation gf108 [geforce GT 540 m] (Rev ff) (prog-If ff)

The installation of an independent video card driver is successful, but it is also complicated. It is not necessary to think about it, because for this dual-card machine, the Integrated Video Card is generally very strong, there is no large game in Linux, at most, just watch movies. It's enough, including special effects. It's okay. It seems that the independent video card is redundant. Maybe it's a little stronger than my CPU ,, but I can still watch p high-definition movies in my previous netbook, so I think that even if the processor almost does not need an independent video card, unless you use a video card to implement some special tasks, in one sentence, your computer can be used normally.
If you have to worry about it, what should you do? There is a way, although NVIDIA Optimus does not plan to support Linux, someone has solved it.
Ubuntu is easy to operate.
