Arg ! skype segfaults in my fresh 13.04 install ! It’s a rather easy fix discussed at community.skype.com simply load skype like this:
LD_PRELOAD=/usr/lib/i386-linux-gnu/mesa/libGL.so.1 skype

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
[...] display-setup-script=setxkbmap no [...]
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
