After 10 Jan 2018 upgrade, suddenly only one of the dual monitors works, the
other one can't be recognized.
I'm current using the i3-window manager as my primary desktop environment, but
I can't login in ubuntu default desktop environment as well, when I tried to
login, it automatically logout and return to the login page.
Here is some of my graphic card information, don't know if it is useful
