Ubuntu 17.10 Artful Aardvark is expected to be released today October 19, with changes that may distract some distribution friends. Canonical's new operating system leaves the familiar Unity interface for GNOME 3.
Gnome 3.26.1 will be the default desktop of Artful Aardvark, and will run through the Wayland display server.
But those who want to use the X11 display server, instead of Wayland there will be the choice “Ubuntu on Xorg” via screenGDM (GNOME Display Manager) connection. Among the options will be the vanilla GNOME 3.26 session without the modifications made by Canonical, but also the old Unity desktop.
So then in a while you will be able to download the operating system Ubuntu 17.10, but only for 64 bit computers, as Canonical has decided to stop supporting 32 bit installations, although existing installations will still be supported with updates security until the end of the life of the respective edition.
Ubuntu 17.10 is powered by the Linux 4.13.4 kernel, which could soon be upgraded to a newer version once the operating system is released.
Of course, if you are using older versions like Ubuntu 17.04 (Zesty Zapus) or Ubuntu 16.04 LTS (Xenial Xerus), you can upgrade to Ubuntu 17.10 once it is officially released.

try a switch from Xorg to Wayland or vice versa. If it does not recognize your password you will probably need to change it
