‘dpkg-reconfigure xserver-xorg’ is the command for fixing the Xserver loading problem.

Steps:-

First, log in as a super (or root) user from the console.
Then, run dpkg-reconfigure xserver-xorg (if you’re on Ubuntu and can’t log in as root, run sudo dpkg-reconfigure xserver-xorg).
You will see a window/wizard as ‘Configuring xserver-xorg’ , Just accept the default answer and go to the next one.
At the end of the wizard you will be exited from the configuration window/wizard, then just reboot the system your graphics(GUI) loading problem will be fixed.
