After gdm-3.8.3.1 upgrade along with systemd, gdm no longer displays a login dialog. After starting it activates all my monitors and after about 20-30 seconds I get gnome wallpaper with a clock and a speaker icon buy no login screen I enabled the systemd use flag globally and rebuilt all those packages. I also uninstalled udev. I set the openrc flag in systemd as well. startx runs gnome-3.8 without issue so that is what I am using now. This is what ps -ef | grep gdm shows after I cntl-c out of the failed gdm launch: root 3852 1 0 15:07 ? 00:00:00 /usr/bin/gdm root 3855 3852 0 15:07 ? 00:00:00 /usr/libexec/gdm-simple-slave --display-id /org/gnome/DisplayManager/Displays/_0 root 3860 3855 0 15:07 tty7 00:00:08 /usr/bin/Xorg :0 -background none -verbose -auth /run/gdm/auth-for-gdm-DFMSxn/database -nolisten tcp vt7 root 3880 3855 0 15:07 ? 00:00:00 gdm-session-worker [pam/gdm-launch-environment] gdm 3884 3880 0 15:07 ? 00:00:00 /usr/bin/gnome-session --autostart /usr/share/gdm/greeter/autostart gdm 3887 1 0 15:07 ? 00:00:00 /usr/bin/dbus-launch --exit-with-session /usr/bin/gnome-session --autostart /usr/share/gdm/greeter/autostart gdm 3888 1 0 15:07 ? 00:00:00 /usr/bin/dbus-daemon --fork --print-pid 5 --print-address 7 --session gdm 3891 1 0 15:07 ? 00:00:00 /usr/libexec/at-spi-bus-launcher gdm 3895 3891 0 15:07 ? 00:00:00 /usr/bin/dbus-daemon --config-file=/etc/at-spi2/accessibility.conf --nofork --print-address 3 gdm 3898 1 0 15:07 ? 00:00:00 /usr/libexec/at-spi2-registryd --use-gnome-session gdm 3904 3884 0 15:07 ? 00:00:00 /usr/libexec/gnome-settings-daemon gdm 3991 1 0 15:07 ? 00:00:00 /usr/bin/pulseaudio --start --log-target=syslog gdm 3998 3991 0 15:07 ? 00:00:00 /usr/libexec/pulse/gconf-helper gdm 4001 1 0 15:07 ? 00:00:00 /usr/libexec/gconfd-2 gdm 4008 1 0 15:07 ? 00:00:00 /usr/libexec/dconf-service gdm 4026 1 0 15:07 ? 00:00:00 /usr/libexec/mission-control-5 gdm 4035 1 0 15:07 ? 00:00:00 /usr/libexec/goa-daemon gdm 4511 1 0 15:09 ? 00:00:00 /usr/libexec/gnome-session-failed --allow-logout --extensions
Maybe this is a dupe of bug 476848, please see at the end of logind output looking for errors
Some problems could be solved with gnome-settings-daemon-3.8.4, if not, try: https://bugs.gentoo.org/show_bug.cgi?id=476848#c31
