Watching a few Youtube videos about installation of Solaris 11.4 beta I got an impression that they get a text mode console login and that's about it. There is no Live CD/USB image on Oracle's site, so I did not try. Did anyone already install 11.4, if you did - does it come with XOrg like 11.3 did?
The installer is text only, but after you install the OS you can run "pkg install solaris-desktop" to get Xorg, GNOME 3.24, Firefox, Pidgin, and other packages that were provided by the Live CD/USB images in previous releases.
This is covered in the Solaris 11.4 docs under Installing the Oracle Solaris OS.
