Wrong keyboard layout in lightdm for (k)ubuntu

I’ve had this annoying thing about my keyboard layout being US for my login window in Kubuntu 12.10. This happened after I got a new wireless keyboard with this unifying usb thing at work. I recently upgraded to 13.04 and the error followed, so I dug up the workaround / fix at bugs.launchpad.net .
My fix was adding this to /etc/lightdm/lightdm.conf

Kubuntu update manager has been complaining about failed package download / update

If you, like me, got that really annoying message from update manager regarding failed download of additional data ( usually flashplugin-installer in my case) every time you login, I just found the answer at ubuntu forums .

bind9 using forwarders

I installed bind9 at localhost so that I could setup forwarders for our LAN dns servers + for my Unix dns servers in DMZ ( I don’t have access to configure the LAN dns server, which would be a better option) . I setup something like this in /etc/bind/named.conf.local (Debian type of distro):

zone "windows.domain.servers." IN {
   type forward;
   forward only;
   forwarders { 10.0.0.1; 10.0.0.2; };
};

zone "unix.dmz.servers." IN {
   type forward;
   forward only;
   forwarders { 192.168.0.1; };
};

domain names and forward ip’s has been changed .
With this setup, I could configure my workstation to use localhost for dns queries, and tell /etc/resolv.conf to search for both the domains I want regular access to without typing the fqdn .
But there was a problem getting answers from my unix dns server in DMZ, /var/log/syslog told me something like:

Nov 15 09:27:07 uranus named[8184]:   validating @0x7f94784dgd70: unix.dmz SOA: got insecure response; parent indicates it should be secure
Nov 15 09:27:07 uranus named[8184]: error (no valid RRSIG) resolving 'lb01.unix.dmz.servers/DS/IN': 192.168.0.1#53
Nov 15 09:27:07 uranus named[8184]: error (no valid DS) resolving 'lb01.unix.dmz.servers/A/IN': 192.168.0.1#53

Since I haven’t got time to debug this stuff in detail, I simply edited /etc/bind/named.conf.options and setup

dnssec-validation no;

And my localhost bind9 could resolv stuff from our DMZ
