gnome-settings-daemon crashed with SIGSEGV in idle_set_mode()

[Jim Read]

The settings enforcer will crash randomly. When I run it through a terminal, it gives me a varying amount of text for varying purposes, followed by Segmentation Fault (core dumped)

After restarting it more than once, my mouse pointer doesn't work through my synaptics touchpad. Don't know if it's related, but it seems to be.

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.

This also happened to me. Since it seems that it still isn't fixed, I created a bug upstream:
https://bugzilla.gnome.org/show_bug.cgi?id=675048

[Arnoques (arnoques)]

Bug fixed in gnome-settings-daemon version 3.4.2 (at least, I'm not sure). The fix was http://git.gnome.org/browse/gnome-settings-daemon/commit?id=0fc947c590ec40f492af16cef5e3de7775ba08ab
