Black screen after login on account in Asus-laptop of 16.04

This question had been asked multiple times but since they're almost older than two years, I will ask it again. The answers to those question couldn't help me either.

My problem:
After logging in on my account I get a black screen. I don't even see my cursor. I did not change major settings and the problem occurred randomly. When I start a guest session, everything works fine.
I don't know if it's worth mentioning but when I take a screenshot, I see two desktops in the output. Like this. I don't have anything plugged in.

Steps taken:

• The solution in this question doesn't work. The file in the mentioned directory doesn't exist.
• Multiple answers on this subject mention (NVIDIA) drivers. As far as I know, no drivers have been installed/updated by me nor did I edit settings related to graphics. My laptop isn't Dual-Boot either and I erased the entire disk and replaced Windows with Ubuntu (through the Ubuntu installation screen). So existing drivers where probably deleted.

My OS Type: Ubuntu 16.04 LTS (regular), 64-bit

My Hardware:

Hardware: Asus laptop R500V
Processor: Intel Core i5-3210M
CPU: 5GHz × 4
Graphics: Intel Ivy Bridge Mobile
Graphics Card: NVIDIA Corporation GF199m [GeForce 610M]

I hope I've given enough information and I hope you can help me.

Solution 1:

I found out why the screen turns black when I login on my personal account. It appears I have accidentally pushed a button that toggles between monitors/beamers when connected. When nothing is connected to the laptop the build-in screen still turns off. This is done by pressing Fn+F8. This is applicable for the Asus R500V series

My thanks to the people who tried to help me. I'm in the process of learning Ubuntu and your suggestions/answers helped my understanding of the OS.

Solution 2:

There are many possible causes for this problem. And thus, there are many solutions, some of which might work for someone else but not you.

That said, give this a try:

1. Open up tty1 on the logon screen by pressing Ctrl+Alt+F1

2. Login at the prompt.

3. Then run these commands:

   sudo rm .Xauthority
   sudo shutdown -r now
