When installing Xubuntu18.04, it crushed at login account registration.

[[e-mail]]

Xubuntu 18.04 (32bit), not 18.04.1.
Installing from Live USB Pendrive.

There were a couples of failures of installation, and finally I got to point where I can create my login name and password. But it crushed during typing my login name.
Therefore I don't know how to take a installation log file.

Previously I had Ubuntu 11.04 and Manjaro (32bit),which were deleted for fresh installation. But I didn't remove GRUB2 for your info.

Thank you for your attention.
