Virtual machine Ubuntu16.04 The system is running in Low-graphics mode solution!!

Virtual machine Ubuntu16.04 cannot enter the graphical interface the system is running Low-graphics mode installed virtual machine Ubuntu16.04 64-bit can be used normally, After installing many software packages (caffe), I do not know where the configuration problem occurs, the system is running in Low-graphics mode error, try a variety of methods, the following methods apply:

1.CTRL+ALT+F1 entering the console

2. Enter the user name and password to enter the system

3. Enter the following command:

1. Cd/etc/x11
2. sudo cp xorg.conf.failsafe xorg.conf
3. sudo reboot

Remember to enter the system after the contents of this file clear (Clear!!) Not deleted!! Don't ask me what the principle is. I will not, otherwise the system resolution will be very low, the operation will have a card one card feeling. All is tears, looked for one hours only then summarizes the method.
