I am windows user and needed to switch to ubuntu for my research. I downloaded 64 bit Ubuntu 17.10 iso and made a an UEFI bootable USB for install.
Then I made some changes from legacy support to UEFI based boot selection.
Everything happened smoothly and I successfully installed a UEFI bootable Ubuntu which smoothly launches until user ID prompt. After I enter the password I am left with a frozen screen as attached. Then all I had is to hold power button to turn off.
I have tried all the possible help from google but this doesn't go away?
