Ubuntu 17.10 Artful Aardvark is expected to be released today, October 19, with changes that may upset some friends of the distribution. New functional Canonical is leaving the familiar Unity desktop for GNOME 3.
Gnome 3.26.1 will be the default Artful Aardvark desktop, and will run through the Wayland display server.
But those who want to use the X11 display server instead of Wayland will have the option of "Ubuntu to Xorg" via the GDM (GNOME Display Manager) login screen. Options include the vanilla GNOME 3.26 session with no modifications made by Canonical, as well as 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 usesolder versions such as 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
