Comment 11 for bug 656988

@Mehdi Fattahi: The archlinux bug that you are referring to has to do with a different bug that is specific to the Iranian layout,
https://bugs.freedesktop.org/show_bug.cgi?id=30548
This bug was fixed in xkeyboard-config on 1st Oct 2010 (8 days ago) with
http://cgit.freedesktop.org/xkeyboard-config/commit/?id=e5c77e30a9457a301e0a3857db450310584dae1a
You need to make sure that the fix goes into Ubuntu 10.10.

You all need to get your act together.
After verifying that the layouts do not switch automatically (the part of about testing the new PPA package), you need to
Compare http://cgit.freedesktop.org/xkeyboard-config/commit/?id=e5c77e30a9457a301e0a3857db450310584dae1a
with /usr/share/X11/xkb/symbols/ir

If they are different, you need to file a new bug report for project 'xkeyboard-config' that asks to update the Iranian ('ir') keyboard layout file from upstream. This is something that you should have done since the 1st Oct.

Good luck!
