And so... considering information that was mentioned by previous
posters, I did some investigation. First of I do not use any DM, I'm
also big antifan of various useless deamons like gconf and dconf, and
even before posting here I disabled them. I also do not run IBus. So
that basically left me with very little files. So I used inotify on
/etc/default/keyboard, and lo and behold something reads it, with no
reason. Though getting the process that does that was a bit more
difficult as inotify does not provide such information. I found that I
can do this with auditd, so I setup fs audit:

auditctl -w /etc/default/keyboard -p war -k culprit

And after significant waiting [almost a day, I do not turn my machine
off] (strangely moments before resets happened like once every 2-5
minutes, like 10 times in a row), I get keyboard reset, inotify reports
file access, and here is what audit shows:

# ausearch -f /etc/default/keyboard
time->Thu Dec  4 09:16:47 2014
type=PATH msg=audit(1417677407.634:1120389): item=0 name="/etc/default/keyboard" inode=524629 dev=08:06 mode=0100664 ouid=0 ogid=0 rdev=00:00 nametype=NORMAL
type=CWD msg=audit(1417677407.634:1120389):  cwd="/"
type=SYSCALL msg=audit(1417677407.634:1120389): arch=c000003e syscall=2 success=yes exit=5 a0=7ffff3668ff0 a1=80000 a2=1b6 a3=0 items=1 ppid=9235 pid=8863 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm="systemd-udevd" exe="/lib/systemd/systemd-udevd" key="culprit"

Now all I can say is that I suspected that something like that will be
responsible for this. For a very long time now I have very hard time
saying anything positive about systemd, this does not make it better.
Considering that this is /dev related I'm pretty sure I can not simply
nuke it without some unpeasant consequences. In any case, we now know
what is causing it (well at least process-wise). Anyone has any
suggestions how to work around this? And if fix can be expected?

Title:
  Keyboard layout changing randomly

Status in gnome-settings-daemon package in Ubuntu:
  Confirmed
Status in unity-settings-daemon package in Ubuntu:
  Confirmed

Bug description:
  Just upgraded from 12.04 (raring) to 12.10 (saucy) and keyboard layout keeps changing from pt_br to what I think is en_us.
  It seems random so I don't know what trigger this, but sometimes just alt-tabbing is enough to mess with keyboard layout in one of the windows.
  I already removed the en_us from my keyboard sources, double checked the use of one source for all windows, and even removed accelerators to switch between layouts but none have worked.
