the system starts "gdm", but this maps to the default gdm selected by "update-alternatives". Since gdm is not installed, but lightdm is, update-alternatives automatically selects lightdm to start with:
# update-alternatives --get-selections x-session-manager auto /usr/bin/startxfce4 x-window-manager auto /usr/bin/metacity This does indeed start lightdm and in tune lightdm starts lightdm-gtk-greeter. But after successfully logging in lightdm does not start the desktop! I have to switch to a console, login as user, stop lightdm, then start X11 with "startxfce4" to have my desktop shown. /etc/lightdm holds only: drwxr-xr-x 2 root root 4.0K Jan 30 2015 lightdm.conf.d/ -rw-r--r-- 1 root root 51 Dec 19 20:59 lightdm.conf -rw-r--r-- 1 root root 2.7K Apr 11 2016 lightdm-gtk-greeter.conf -rw-r--r-- 1 root root 452 Oct 30 2014 users.conf the only changed file: lightdm.conf holds: [SeatDefaults] greeter-session=lightdm-gtk-greeter An other file in lightdm.conf.d has: [SeatDefaults] user-session=xubuntu But combining these into one does not change anything. lightdm starts, handles login, but does not start my desktop environment. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gdm3 in Ubuntu. https://bugs.launchpad.net/bugs/1611433 Title: gdm does not start after upgrade from 14.04.4 LTS to 16.04.1 LTS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1611433/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
