Though I've not experienced exactly this bug, I've got exactly the same
symptoms in other circumstances. During restarts of GDM3 and in attempts
to change config.
Having had a look at how the permissions of
/var/lib/gdm3/dconf/profile/gdm get messed up, I've believe I've found
the culprit. The section of the init script which sees if the
configuration needs converting from gconf to dconf style settings:
if [ "$needed" = yes ]; then
rm -rf /var/lib/gdm3/dconf
mkdir -p /var/lib/gdm3/dconf/profile
/var/lib/gdm3/dconf/db/gdm.d/locks
ln -s /usr/share/gdm/dconf-profile /var/lib/gdm3/dconf/profile/gdm
ln -s /usr/share/gdm/dconf/*-settings /var/lib/gdm3/dconf/db/gdm.d/
ln -s /usr/share/gdm/dconf/locks/*-locks
/var/lib/gdm3/dconf/db/gdm.d/locks/
# The configuration file in /etc uses org.gnome.blah gsettings syntax.
# Convert it to org/gnome/blah dconf syntax.
awk '/\[.*\]/ { gsub("\\.","/"); } ! /^#/ { print;}' \
/etc/gdm3/greeter.gsettings >
/var/lib/gdm3/dconf/db/gdm.d/90-debian-settings
dconf update /var/lib/gdm3/dconf/db 2> /dev/null
fi
will write as root, making the directories in question unwritable by
Debian-gdm, and hence the window manager won't run.
Cheers,
Bem
