Package: xfce4-power-manager
Version: 1.2.0-2
Severity: important
It has been going on for a while but I do not remember exactly after which upgrade.
I am running awesome as a window manager for XFCE4. Whenever I connect to external monitors, or disconnect from them I issue xrandr commands e.g.
xrandr --output $LVDS --off
xrandr --fbmm 520x326 \
--output DP1 --same-as LVDS1 --mode 1920x1200 \
--output VGA1 --mode 1920x1200 --rotate left --right-of DP1 \
--output LVDS1 --off \
|| xrandr --output $LVDS --mode 1440x900
where LVDS is set to output of xrandr | awk '/LVDS/{print $1;}'
then some times (not always but often) xfce4-power-manager crashes with
the following traceback:
