I solved this problem by re-install the OS. When I install the OS, I did not check the checkboxes to install updates and third-party software (I checked to install third-party software last time). Therefore the nouveau driver instead of the NVIDIA one will be installed. Then I changed the apt source to a local software mirror, and use Ubuntu Drivers to install the NVIDIA driver. And everything now works fine.
  I think the problem may caused by incomplete install on the NVIDIA driver. Since I am in mainland China, the network may be the primary reason for this incomplete install.

During the above procedure, I found that the OS will become extremely slow in the following situation.
- Using nouveau driver.
- The laptop internal display is disabled (lip off or disabled in Display Setting).
- The external monitor is the only display.
I did not investigate deeper and I quickly installed the NVIDIA driver.

Thanks for the help!
