The boot works fine until the pink Ubuntu screen appears for a minute or so and then black screen shows up with some text.

enter image description here

My problem is that the GUI display isn't opening, but the original TTY CLI is working fine. When I run xhost command on it, it says xhost : unable to display ''''

I am using Ubuntu 18.04 on a 16GB Sandisk pendrive as bootable stick on a Windows 7 Lenovo IdeaPad Z560 PC.

it doesn't seem xhost(GUI) thing, but seems more like there is bad sector in boot-sector. this did magic. just, make new bootable-usb of the same ubuntu version.Then, boot up the pc with both the bad pendrive and newly made bootable-usb plugged in.This(bootable-usb) guides you to Install or Savemode.and choose Savemode.Now you see the friendly used-to normal screen of ubuntu.Then use aplication called 

BOOTREPAIR

just double click and run it.This repairs your bad sector of boot-sector in the pendrive.Then shutdown PC.Making sure to plug out newly made bootable-usb and Finaly, plugin the pendrive and boot. that's it!!!
