Hi,
I am new to this , so dont know if it would help.
I was facing the same issue but on ubuntu 12.04 precise [Kernel 3.2.04]
and gnome-settings-daemon version 3.2.2 . My system is toshiba
sattellite L305-D .
After looking into the issue i found out the the whenever i leave the
system Idle for around a minute there was a crash only when i login with
out pluging in the power cable.
I did the following to fix the segmentation fault.
File: plugins/power/gsd-power-manager.c
Adding the following at line 2264 backlight_helper_get_value
// after getting the long value should be checked for lesser than 0 value also
// Line: 2319
if (value > G_MAXINT || value < 0 ) {
// this will fix the seg fault
For some reason I always get -5 value in
/sys/class/backlight/toshiba/brightness irrespective of logging on with power
cable plugged or without it.
I will look into it later.
Hope it helps.
