I found a workaround to use nvidia driver with lightdm + gnome-shell.
WIth nvidia-331 driver, lightdm and gnome-shell, in "System Settings" (gnome-control-center) --> "Displays", I can still see two displays "Built-in DIsplay" and "Unknown Display". This is the same to "Intel driver" situation. All the layout problems I met so far can be fixed by turning off "Unknown Display" in gnome-control-center. After turning off the "Unknown Display", gnome-shell works perfectly. And then I tried to launch "nvidia-settings", it shows "CRT-0 Off". I am thinking the "Unknown Display" might be refer to CRT-0 (VGA-0) ?
Note: I tried to configure "nvidia-settings" layout, it does not work. In "nvidia-settings", It only has CRT-0. (CRT-0 is using "X Screen 0" configuration. and in "X Screen 0" --> "X Server XVideo Settings", it shows CRT-0 is the same as VGA-0. Hopefully, this paragraph is not confusing you.)
PS: I am not sure how to upload multiple files at once or even if that is possible in launchpad. I will upload three screenshots to make my words more clear.
nvidia-builtin-display.png is a screenshot which shows built-in display setup in gnome-control-center before turning off "Unknown Display".
nvidia-unknown-display.png is a screenshot which shows unknown display setup in gnome-control-center before turning off "Unknown Display".
nvidia-turnoff-unknown.png is a screenshot after turning off "Unkown Display". You can see that the layout looks perfectly by turning it off.
I have no idea why both intel driver and nvidia driver think I have an extra "Unknown Display" VGA-0 or CRT-0.
In the end, I will show the final "xrandx -q" output after turning off "Unknown Dispaly":
