Ubuntu has switched their default desktop from Unity to GNOME in Ubuntu 18.04. Unfortunately they decided to keep the same xsession name ("ubuntu"). That means that our default configuration thinks this is unity, and not GNOME. Besides showing the wrong information in the profile chooser, this also hides the real Unity and prevents it from being started.
Installing Unity on Ubuntu 18.04 is quite simple: > sudo apt install ubuntu-unity-desktop The result is this: cendio@ubuntu1804:~$ cat /usr/share/xsessions/ubuntu.desktop [Desktop Entry] Name=Ubuntu Comment=This session logs you into Ubuntu Exec=env GNOME_SHELL_SESSION_MODE=ubuntu gnome-session --session=ubuntu TryExec=gnome-shell Type=Application DesktopNames=ubuntu:GNOME X-Ubuntu-Gettext-Domain=gnome-session-3.0 cendio@ubuntu1804:~$ cat /usr/share/xsessions/unity.desktop [Desktop Entry] Name=Unity Comment=This session logs you into Unity Exec=/usr/lib/gnome-session/run-systemd-session unity-session.target TryExec=unity Type=Application DesktopNames=Unity:Unity7:ubuntu X-Ubuntu-Gettext-Domain=gnome-session-3.0
My suggestion is that we have these profiles: * GNOME (looks for gnome.desktop) - will not be found on ubuntu 18.04 - will work on other distros * Ubuntu (looks for ubuntu.desktop) - will choose the default ubuntu desktop environment (gnome OR unity) - will work on all ubuntu versions * Unity (looks for unity.desktop) - for the people who wants to use unity on ubuntu 18.04 - will not be found on older ubuntus This would mean creating a new "Ubuntu"-profile and changing the xdg_session of the Unity profile.
(In reply to comment #2) > * GNOME (looks for gnome.desktop) > - will not be found on ubuntu 18.04 That was incorrect, it is possible to do "apt install gnome-session" on ubuntu 18.04 and get a gnome.desktop.

Should be all done now.
Nice. All three profiles are correctly separated and working well. Tested on Ubuntu 16.04 and 18.04. > * The GNOME desktop on Ubuntu 18.04 should not be listed as Unity in the profile chooser. Works. > * The Unity desktop should always be available from a fitting profile when installed. It is. As "Unity" when it is its own thing, and "Ubuntu" when it is the default Ubuntu desktop.
