Lubuntu Post Installation

Every time I install a fresh copy of Lubuntu on one of my devices I have to think a long time what apps to install after the default install and what changes I normally do to config files etc. Since I'm sharing a very common problem to a whole lot of others (I'm getting older every day :-) I decided to write some kind of recipe to cook my own installation to save tons of time next time (what at poem, ain't it?! :-).

/etc/apt/apt.conf
/etc/apt/apt.conf.d/30proxy on newer systems (Ubuntu 16.04 and above)

else PS1='\n[\[\033[32m\]\u\[\033[00m\] @ \[\033[01;33m\]\h\[\033[00m\]] `pwd` (\t) \[\033[32m\]$\[\033[00m\] '

Install RDP-Server on Lubuntu:

vi /home/user/.xsession -> lxsession -e LXDE -s Lubuntu
systemctl restart xrdp

"Mixxx" is an open-source DJ-ing software. Forget about spending your hard earned money in Traktor, BPM-Studio etc., Mixxx is all you need!

sudo -E add-apt-repository ppa:mixxx/mixxx
sudo -E add-apt-repository ppa:mixxx/mixxxbetas
sudo apt-get update
sudo apt-get install mixxx

"XEN" is an open source virtualization software (in fact a hypervisor), it is not as easy and plug-and-play as VirtualBox for example, but definitely worth giving a try.

sudo apt-get install xen-hypervisor-amd64 xen-tools virt-manager ssh-askpass

"Touchpad-Indicator" is a superb utility to tweak your notebook's touchpad, mainly to get rid of that "Natural Scrolling" (who on God's earth invented that term??). Have a look here..

"Camera Monitor" is a nice tool if you own a web cam and you want to know it's status (especially for the ones built-in in netbooks/notebooks, they often have no power indicator!). Download the up-to-date package at Launchpad and then run

sudo apt-get install python-pyinotify
sudo dpkg -i cameramonitor-xyz.deb

or add the PPA and install from there.

"SAMBA4" is a possible replacement for Windows AD-DCs. Setting it up as DC is rather simple, just delete the standard smb.conf and run:

sudo samba-tool domain provision --use-ntvfs --realm=mydom.test --domain=MYDOM --server-role=dc --dns-backend=SAMBA_INTERNAL --adminpass="xxxxx"

Add these lines to /etc/samba/smb.conf to provide DNS services also to your clients:

dns forwarder = 8.8.8.8
# dns recursive queries = yes # not working, remove it

and run this command on your linux box:

net rpc rights grant 'SAMDOM\Domain Admins' SeDiskOperatorPrivilege -U'SAMDOM\administrator' -I dc1.samdom.example.com

To check the status, use:

net rpc rights list accounts -U'SAMDOM\administrator' -I dc1.samdom.example.com

Don't forget to add "winbind" to the passwd and group entries in /etc/nsswitch.conf !

"MySQL" database for ownCloud:

mysql -uroot -p

mysql> CREATE USER 'username'@'localhost' IDENTIFIED BY 'password';
mysql> CREATE DATABASE IF NOT EXISTS owncloud;
mysql> GRANT ALL PRIVILEGES ON owncloud.* TO 'username'@'localhost' IDENTIFIED BY 'password';

Wipe your hard disk with dd

dd if=/dev/zero of=/dev/sdX bs=1M &
while [ -e /proc/xxxxx ] ; do kill -USR1 xxxxx ; sleep 10 ; done

Repair broken boot loader

set prefix=(hd0,1)/boot/grub
set root=(hd0,2)
insmod linux
insmod normal
normal

Fix mscorefonts package not installing

wget ftp.de.debian.org/debian/pool/contrib/m/msttcorefonts/ttf-mscorefonts-installer_3.6_all.deb
sudo dpkg -i ttf-mscorefonts-installer_3.6_all.deb

Get rid of this f**king systemd-resolved.service

systemctl disable systemd-resolved.service
service systemd-resolved stop
rm /etc/resolv.conf
apt install dnsmasq
systemctl disable dnsmasq.service
vi /etc/NetworkManager/NetworkManager.conf

Add "dns=dnsmasq" to [main] section.
