[Pkg-xfce-devel] Bug#760740: lightdm leaves at-spi process behind after login

[sthibault at debian.org (Samuel Thibault)]

Package: lightdm
Version: 1.10.1-3
Severity: important
User: debian-accessibility at lists.debian.org
USertags: a11y

Hello,

After a fresh Jessie install of Debian with the XFCE desktop and logging
in with the user created at installation ("joe"), there are some
processes left behind by lightdm, running ad lightdm user, notably:

lightdm    509  0.0  0.0  24340   588 ?        S    14:45   0:00 /usr/bin/dbus-launch --autolaunch 1b4e071b23e9498f9e505e31c68727f0 --binary-syntax --close-stderr
lightdm    510  0.0  0.1  41580  1116 ?        Ss   14:45   0:00 /usr/bin/dbus-daemon --fork --print-pid 5 --print-address 7 --session
lightdm    512  0.0  0.3 337456  3180 ?        Sl   14:45   0:00 /usr/lib/at-spi2-core/at-spi-bus-launcher
lightdm    516  0.0  0.1  41580  1720 ?        S    14:45   0:00  \_ /usr/bin/dbus-daemon --config-file=/etc/at-spi2/accessibility.conf --nofork --print-address 3
lightdm    519  0.0  0.3 125220  3512 ?        Sl   14:45   0:00 /usr/lib/at-spi2-core/at-spi2-registryd --use-gnome-session

The at-spi-bus-launcher and at-spi2-registryd are problematic: since
they are there on the X display, joe's session can not start its own
at-spi-bus-launcher and at-spi2-registryd, thus leading to an
inaccessible desktop.

Lightdm must make sure not to leave behind at-spi-bus-launcher and
at-spi2-registryd running on the display.
