I'm using Ubuntu 16.04 without a desktop manager.
When my system is started, it goes to tty0, and the screen appears like this:
<my-pc-name> login: |
| represents the cursor.
After a few seconds my cursor shifts to the beginning of line like this:
I can login "normally", but when I type my username, the new text overwrites all text to the right of the cursor (i.e., the login prompt).
When I use Ctrl+Alt+F2 to switch to tty1, this problem has not happened.
How can I debug this?
