Package: xfce4-session Version: 4.12.1-3 Severity: normal Dear Maintainer,
Since a few days, my testing system (updated almost daily) issues a strange behaviour in starting the XFCE4 desktop : the window manager isn't started, and the top most panel doesn't start, whereas another panel and some apps started at session start appear. Restarting X eventually works again corrctly (lightdm + xfce4). Here's an excerpt of .xsession-errors when that happend : Xsession: X session started for olivier at vendredi 29 avril 2016, 09:36:34 (UTC+0200) export DESKTOP_SESSION='xfce' export DISPLAY=':0' export GDMSESSION='xfce' export GDM_LANG='fr_FR.utf8' export HOME='/home/olivier' export LANG='fr_FR.UTF-8' export LOGNAME='olivier' export PATH='/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games' export PWD='/home/olivier' export SHELL='/bin/bash' export USER='olivier' export XAUTHORITY='/home/olivier/.Xauthority' export XDG_CURRENT_DESKTOP='XFCE' export XDG_GREETER_DATA_DIR='/var/lib/lightdm/data/olivier' export XDG_RUNTIME_DIR='/run/user/1000' export XDG_SEAT='seat0' export XDG_SEAT_PATH='/org/freedesktop/DisplayManager/Seat0' export XDG_SESSION_DESKTOP='xfce' export XDG_SESSION_ID='6' export XDG_SESSION_PATH='/org/freedesktop/DisplayManager/Session0' export XDG_SESSION_TYPE='x11' export XDG_VTNR='7' localuser:olivier being added to access control list openConnection: connect: Aucun fichier ou dossier de ce type cannot connect to brltty at :0 dbus-update-activation-environment: setting USER=olivier dbus-update-activation-environment: setting XDG_SESSION_TYPE=x11 dbus-update-activation-environment: setting HOME=/home/olivier dbus-update-activation-environment: setting DESKTOP_SESSION=xfce dbus-update-activation-environment: setting XDG_SEAT_PATH=/org/freedesktop/DisplayManager/Seat0 dbus-update-activation-environment: setting GTK_MODULES=gail:atk-bridge dbus-update-activation-environment: setting QT_LINUX_ACCESSIBILITY_ALWAYS_ON=1 dbus-update-activation-environment: setting DBUS_SESSION_BUS_ADDRESS=unix:abstract=/tmp/dbus-wuKq4WtPn9,guid=b7716e2838bf9ce5b381304a57230f03 dbus-update-activation-environment: setting LOGNAME=olivier dbus-update-activation-environment: setting PATH=/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games dbus-update-activation-environment: setting GDM_LANG=fr_FR.utf8 dbus-update-activation-environment: setting XDG_SESSION_PATH=/org/freedesktop/DisplayManager/Session0 dbus-update-activation-environment: setting XDG_RUNTIME_DIR=/run/user/1000 dbus-update-activation-environment: setting DISPLAY=:0 dbus-update-activation-environment: setting LANG=fr_FR.UTF-8 dbus-update-activation-environment: setting XDG_CURRENT_DESKTOP=XFCE dbus-update-activation-environment: setting XDG_SESSION_DESKTOP=xfce dbus-update-activation-environment: setting XAUTHORITY=/home/olivier/.Xauthority dbus-update-activation-environment: setting XDG_GREETER_DATA_DIR=/var/lib/lightdm/data/olivier dbus-update-activation-environment: setting SHELL=/bin/bash dbus-update-activation-environment: setting GDMSESSION=xfce dbus-update-activation-environment: setting QT_ACCESSIBILITY=1 dbus-update-activation-environment: setting UDEdir= dbus-update-activation-environment: setting GPG_AGENT_INFO=/home/olivier/.gnupg/S.gpg-agent:0:1 dbus-update-activation-environment: setting PWD=/home/olivier dbus-update-activation-environment: setting XDG_DATA_DIRS=/usr/share/xfce4:/usr/local/share/:/usr/share/ dbus-update-activation-environment: warning: error sending to systemd: org.freedesktop.DBus.Error.Spawn.ChildExited: Process org.freedesktop.systemd1 exited with status 1 /usr/bin/startxfce4: X server already running on display :0 xfce4-session: GNOME compatibility is enabled and gnome-keyring-daemon is found on the system.
