Ah what an amazing display. I find the englightment is very light so I try to install it to my notebook. Here are the steps I read from the source.

sudo apt-get install automake autopoint build-essential ccache check \
doxygen faenza-icon-theme git imagemagick libasound2-dev libblkid-dev \
libbluetooth-dev libbullet-dev libcogl-dev libfontconfig1-dev \
libfreetype6-dev libfribidi-dev libgif-dev libgstreamer1.0-dev \
libgstreamer-plugins-base1.0-dev libharfbuzz-dev libibus-1.0-dev \
libiconv-hook-dev libjpeg-dev libblkid-dev libluajit-5.1-dev \
liblz4-dev libmount-dev libopenjpeg-dev libpam0g-dev \
libpoppler-cpp-dev libpoppler-dev libpoppler-private-dev \
libproxy-dev libpulse-dev libraw-dev librsvg2-dev libscim-dev \
libsndfile1-dev libspectre-dev libssl-dev libsystemd-dev \
libtiff5-dev libtool libudev-dev libudisks2-dev libunibreak-dev \
libvlc-dev libwebp-dev libxcb-keysyms1-dev libxcursor-dev \
libxine2-dev libxinerama-dev libxkbfile-dev libxrandr-dev \
libxss-dev libxtst-dev linux-tools-common texlive-base \
unity-greeter-badges valgrind xserver-xephyr

Just copy paste the code above. And let everything is installed. Remember you must have an internet connection. Then, restart the notebook and you will have the englightment desktop.

Removing Zeitgeist Daemon from Ubuntu 12.04

Published by:

Zeitgeist is a service that control the user log.

From Wikipedia:

Zeitgeist is a service which logs the users’s activities and events, anywhere from files opened to websites visited and conversations. It makes this information readily available for other applications to use in form of timelines and statistics. It is able to establish relationships between items based on similarity and usage patterns by applying data association algorithms such as “Winepi” and “A Priori”

Zeitgeist is the main engine and logic behind GNOME Activity Journal which is currently seen to become one of the main means of viewing and managing activities in GNOME version 3.0

I think I want to try to ‘silent’ my laptop so I have no track. So I will uninstall it.

#root:/apt-get purge libzeitgeist-1.0-1 python-zeitgeist zeitgeist-core

Let’s see.

Ubuntu 14.04 with Grasehotspot 3.8 error because p2p1 network card name

Published by:

Menginstal grasehotspot yang merupakan software berbasis web untuk mengatur lalu lintas user internet berupa hotspot merupakan tantangan sendiri di Ubuntu 14.04. Dengan cpu dan motherboard keluaran terbaru. Seperti beberapa hari ini saya mencobanya di I5 + 8Gb DDr3 + motherboard (gigabyte mungkin) cukup memberikan pelajaran yang sangat bernilai.

Pertama, ubuntu 14.04 ternyata memberikan penamaan lan port yang sesuai dengan keberadaan port nya. Os ini tidak lagi menggunakan eth0 dan seterusnya, tapi dengan kode seperti p2p1 dan p3p1. Kira-kira demikian. Ketika masuk pada instalasi grasehotspot, maka barulah konfigurasi ini mengalami keanehan.

Yaitu program hotspot yang berjalan mulus di server, sekarang tidak jalan. Client tidak mendapatkan ip dari server. Ketika diperiksa di server, dengan perintah sudo ifconfig

Hasilnya ada urusan internet dengan p2p1 dan p3p1. Sebenarnya server internet berjalan, tapi device lain yang akan menggunakan grasehotspot, tidak jalan.

Salah satu solusinya adalah merubah penamaan p2p1 dsb tersebut kembali ke eth0 dan atau eth1.

Disini ada satu sumber bagaimana melakukannya : link

Langkah pertama yang disebutkan disana adalah mengubah parameter boot melalui grub.
Edit /etc/default/grub misalnya dengan vi atau nano editor

root@server:#nano /etc/default/grub

edit line dengan parameter di bawah dan isikan seperti tercantum

GRUB_CMDLINE_LINUX_DEFAULT=”net.ifnames=1 biosdevname=0″

Create if none and edit if any the /etc/udev/rules.d/70-persistent-rules
Find out the p2p1 and p3p1 mac address that we can find out with

root@server:#ifconfig

Now edit

root@server:#nano /etc/udev/rules.d/70-persistent-rules

Add these line

SUBSYSTEM==”net”, ACTION==”add”, ATTR{address}==”macadress”, NAME=”eth0″
SUBSYSTEM==”net”, ACTION==”add”, ATTR{address}==”macadress”, NAME=”eth1″

Dont’ forget to change the network configuration if static

root@server:#nano /etc/network/interfaces

Change any setting with p2p1 or p3p1 to eth0 and eth1. After that restart the computer.

It should be eth0 and eth1. So the grasehotspot should be running like mine.

My Ubuntu Goes to BusyBox On Startup

Published by:

This is happened because the electricity in my city is black out. When I start my laptop, it show the bootloader option but after I pressed enter, the system can not boot into the operating system. It is said that it can not mount sda.

I try to access it using the boot operating system through my flash disk, but I can’t mount the sda.

After I read in ubuntuforum, I try this command.

sudo e2fsck -f -b 32768 -y /dev/sda1

After It done doing some processing, I reboot and the system back to normal

firefox (in ubuntu) libavcodec error

Published by:

The error I meant is the message displayed at the top of the firefox, said libavcodec is vulnerable and expired (for some reason). After googling and find the article in http://askubuntu.com/questions/851190/how-to-update-libavcodec-on-ubuntu-14-04, the problem is libavcodec is disabled as default.

Libavcodec is needed to play the streaming in the website. Except for youtube. I still can play youtube with libavcodec disabled. I wonder why.

Anyway the solution is make the libavcodec enable.

Here is how

type about:config in the address bar, enter
click “I accept the risk” search libavcodec
change media.libavcodec.allow-obsolete;false to true

virtualbox shared folder – another way mounting shared folder using samba

Published by:

my host is slackware.
the virtual machine is windows xp.
I am going to add the folder in my slackware into the windows using samba in the slackware.

first setting the samba in the slackware. I think I have another post about samba in this blog. Then in the virtualbox, set the network setting into two nic. The first nic as bridge adapter and the other as nat.

Later in the virtual machine, we will see the lan address of the bridge. Then set it manually to the same network address as host. If the host is 192.168.1.1 then the bridge is 192.168.1.2

Next, through the network browser file manager in windows, browse to 192.168.1.1, we will see the samba share right over there.
