No .ICEauthority file at all in x686 trusty's Kubuntu 14.04.1, Lubuntu 14.04 and 14.04.1.

I detected three cases in installed trusties : there is no .ICEauthority in /home/main_user. Nevertheless users can log in. You can see the phenomenon as soon as the live usb has been burned. You don't even need to install.

I already could reproduce it for
b0d1c58c8515ab40382d01f59655ba85 *lubuntu-14.04-desktop-i386.iso
==============

First case :
Lubuntu iso unknown
lsb_release -d Description: (L)Ubuntu 14.04.1 LTS
uname -r Linux NC10 3.13.0-33-generic

Second case :
MD5: b0d1c58c8515ab40382d01f59655ba85 *lubuntu-14.04-desktop-i386.iso
With updates, according to the kernel.
uname -a Linux NC10 3.13.0-33-generic #58-Ubuntu SMP Tue Jul 29 16:47:17 UTC 2014 i686 i686 i686 GNU/Linux

Third case :
kubuntu iso unknown
lsb_release -d Description: (K)Ubuntu 14.04.1 LTS
uname -a Linux deever-desktop 3.13.0-32-generic #57-Ubuntu SMP Tue Jul 15 03:51:12 UTC 2014
Processor: AMD Athlon(tm) II X2 250

==============
I reproduced the second case with this process :
I took a micro-SD card and washed it up with
sudo dd if=/dev/zero of=/dev/sdx bs=512 count=4000
Then i burned it with usb-creator-gtk 0.2.23, of a Xubuntu 12.04.5
(uname -a
Linux NN 3.2.0-67-generic #101-Ubuntu SMP Tue Jul 15 17:45:51 UTC 2014 i686 i686 i386 GNU/Linux)
and an Intel Atom N270 processor.
Then I plugged it in another pc, with an amd64 AMD Athlon dual core processor 5050e.
And so it was : no .ICEauthority, but i could boot and reboot the live session.
