My system is Linux Mint 18.3 Sylvia Xfce, for bearing the system's machine has been very, very old (Acer Aspire 3680, please do not ridicule why use so old machines, direct change machine... Bala bala, because is... It still can boot... Not willing to part with or use ah... + life lies in with), found that after entering system, all kinds of "the old man dementia", so sudden can not start the graphical interface, direct use text interface (BTW: I have a Linux small white, only have a mint, so... Can only lasted)

Tried to stand in a great god Settings, such as "modify/etc/X11/default - the display - manager files";" Edit/etc/default/grub files ", did not succeed, can display text self-checking process after is switched on, the login link, stay after 2 seconds will automatically enter the graphical interface,

Seek advice...
