Lubuntu - Finaliza a sessão do usuario

Enviado em 13/03/2017 - 17:59h

Boa tarde,
Estou utilizando a versão Lubuntu 16.04 LTS x86 e executando uma aplicação java de automação comercial. O que ocorre é: após uma consulta ao banco de dados, o sistema abre uma janela e assim que isto ocorre, o sistema operacional mata a sessão de usuário. Estranhamente isso ocorre de modo randômico, sendo difícil rever este erro. Acontecem em maquinas distintas com configurações diversas de hardware. Consegui ver o erro ocorrer e estou encaminhando alguns dos logs atualizados após o incidente.

PS.: No sistema operacional Windows, utilizo a mesma aplicação e este erro não ocorre.

Arquivo de configuração:

lightdm.conf
[Seat:*]
autologin-guest=false
autologin-user=pdv
autologin-user-timeout=0
greeter-session=lightdm-gtk-greeter
greeter-hide-users=false

#
# Appearance:
# theme-name = GTK+ theme to use
# icon-theme-name = Icon theme to use
# background = Background file to use, either an image path or a color (e.g. #772953)
# user-background = false|true ("true" by default) Display user background (if available)
# transition-duration = Length of time (in milliseconds) to transition between background images ("500" by default)
# transition-type = ease-in-out|linear|none ("ease-in-out" by default)
#
# Fonts:
# font-name = Font to use
# xft-antialias = false|true Whether to antialias Xft fonts
# xft-dpi = Resolution for Xft in dots per inch (e.g. 96)
# xft-hintstyle = none|slight|medium|hintfull What degree of hinting to use
# xft-rgba = none|rgb|bgr|vrgb|vbgr Type of subpixel antialiasing
#
# Login window:
# active-monitor = Monitor to display greeter window (name or number). Use #cursor value to display greeter at monitor with cursor. Can be a semicolon separated list
# position = x y ("50% 50%" by default) Login window position
# default-user-image = Image used as default user icon, path or #icon-name
# hide-user-image = false|true ("false" by default)
#
# Panel:
# panel-position = top|bottom ("top" by default)
# clock-format = strftime-format string, e.g. %H:%M
# indicators = semi-colon ";" separated list of allowed indicator modules. Built-in indicators include "~a11y", "~language", "~session", "~power", "~clock", "~host", "~spacer". Unity indicators can be represented by short name (e.g. "sound", "power"), service file name, or absolute path
#
# Accessibility:
# a11y-states = states of accessibility features: "name" - save state on exit, "-name" - disabled at start (default value for unlisted), "+name" - enabled at start. Allowed names: contrast, font, keyboard, reader.
# keyboard = command to launch on-screen keyboard (e.g. "onboard")
# keyboard-position = x y[;width height] ("50%,center -0;50% 25%" by default) Works only for "onboard"
# reader = command to launch screen reader (e.g. "orca")
#
# Security:
# allow-debugging = false|true ("false" by default)
# screensaver-timeout = Timeout (in seconds) until the screen blanks when the greeter is called as lockscreen
#
# Template for per-monitor configuration:
# [monitor: name]
# background = overrides default value
# user-background = overrides default value
# laptop = false|true ("false" by default) Marks monitor as laptop display
# transition-duration = overrides default value
