SegFault in libgdk-3

[Rui Lapa]

I'm using Trusty XFCE with lightdm-gtk-greeter 201411130631~ubuntu14.04.1 on 470x Asus VivoPC i5 (intel graphic).

Using "201411130631" because I need conky to help Helpdesk diagnose network info.
On trusty's version 1.8.5-1ubuntu2, conky steals focus.

Its been randomly normal users locking sessions and when they "wake up" they get a black screen.

The issue seams to be this segfault.

Nov 13 11:17:20 VP0329 kernel: [ 8128.980526] lightdm-gtk-gre[8780]: segfault at 18 ip 00007f0efd547ca0 sp 00007fffe4f1a488 error 4 in libgdk-3.so.0.1000.8[7f0efd50f000+a0000]
Nov 13 09:04:37 VP0329 console-kit-daemon[1785]: GLib-CRITICAL: Source ID 11 was not found when attempting to remove it
Nov 13 11:17:20 VP0329 console-kit-daemon[1785]: GLib-CRITICAL: Source ID 36 was not found when attempting to remove it

Issue is not easily reproducible.

If there's a way to get network indicator I would gladly be back on "stable".

Obviously you can't have a network indicator in the greeter because the network settings are *within* the session and the greeter sits outside of it. (Unless you have a single-user system with global network settings, then it would make sense to show it.)

So you're diagnosing network information on the greeter/lock screen..?

Anyway, that segfault we'll have to look into I guess.

Yes, normally, network indicator is used inside the session.
We need the Ethernet IP address so that "field support" can check basic
network connection, initial checkup/provision and remote authentication.

A basic IP info would be enough, but I could not find a way to use a
network indicator, nor make one.
Even a red/green led based on /sys/class/net/eth0/operstate would do it.
Have any ideas to share another way of getting same info without conky
would be appreciated.
