How to Run Ubuntu 11 04 Natty Narwhal Unity in Acer Aspire One 722 Netbook

Few days ago suddenly out of nowhere the Acer Aspire one 722 (BZ454 to be precise) fell into my hands :P. It came pre-loaded with MS Windows 7 Home Premium (64-bit). But as soon as I got it, I just wanted to try Ubuntu Linux 11.04 in it (obviously). Since, it doesnt have an optical drive, I went with creating a Live Ubuntu USB disk but it did not work!.

Oh it boot the OS alright ... but after displaying the pretty Ubuntu logo, bugger just freezed!. I then search in few forums and realized that others are also having the same issue. I honestly dont know what really is the issue here... but for some reason it just freezes the whole screen.

I also had a bit similar issue with my now old Laptop while I was trying Ubuntu 11.04 using the LiveCD but was able to fix it by first not choosing to run Ubuntu as a live environment but went for the installation straight ahead.

Dudes, I really got in running! :D...

So, since the 722 also comes with a AMD Radeon GPU (which are a bit troublesome with Compiz) I tried the same thing with the Acer Aspire One 722 but when Ubiquity (Ubuntus live Installer Wizard) was just about to launch itself, again, the Netbook just got stuck, again.

This time I saw the Wi-Fi card is turned on automatically thus I guessed that it might be the Wi-Fi detection problem which is pretty common with GNU/Linux these days.

Anyhow, just out of curiosity, I decided to give it a try, again, and this time, when the USB boot-menu was loaded, I pressed the "F6" button and chose "ACIP-Off" option. The system booted but when it arrived where previously freeze-d, this time I got an error message (except for the stuck-non-informative window as with previous occasions) saying that the installer cannot find a live file-system to operate.

Now, Im not an expert on how GNU/Linux Live "environments" work. But when I was creating my Boot-able USB disk I choose the option that says "Discarded on shutdown, unless you save them elsewhere".

the second option is not selected by default... but I guess most of us just use it thus this is where I made my mistake (at lest I thin this is the reason)

So, I just thought re-creating a USB disk using the suggested/default settings called "Stored in extra reserved space" which I did and then, plug-in the USB disk and decided to go with the default Ubuntu 11.04 Live environment and guess what?, it worked!. 

Just make sure that youve chosen this one (selected by default)...

Now Im not entirely sure whats the real cause here, but Ive tested this two times and after going for the default settings, now I can use Ubuntu 11.04 in their pretty Unity desktop interface (yep with Compiz running) even after considering the fact that the Acer Aspire One 722 comes with the AMD fusion (APU - Advanced Processing Unit) which is only fully supported in the Kernel 3.0+, but even after without having that Kernel version + the proprietary AMD/ATI drivers... the Aspire One 722 runs pretty decently without any crashing incidents :).

But to be honest, even after considering the power of the included AMD Radeon HD 6250 (256MB dedicated graphics memory, 280Ghz internal clock speed if Im not mistaken) Unity does feel a little slow since the proprietary AMD/ATI drivers are significantly faster than the open-source drivers, you should install the proprietary drivers if you want the best possible performance out of that GPU.

And also, if you also have this Netbook, then it should be pretty interesting what the upcoming Ubuntu 11.10 could bring from a performance point of view because with 11.10, Canonical is shipping the Kernel 3.0 for the first-time which fully supports the AMD Fusion architecture by default.

Anyhow, the performance even while on the Live USB environment is really good (Im even writing this post in it!) but it should be even better after installing in the HDD.
 
So, if youre having troubles with trying to run Ubuntu 11.04 Natty Narwhal in Acer Aspire One 722 Netbook, then while creating that USB disk, just try the default settings as shown in the third screenshot. Good luck.

Oh and one more thing, the 11.6 inch display has a a resolution of 1366x768 thus things could look a bit too small for some but thanks to the Ubuntu or the Gnome desktops DPI settings, I think Ubuntu Linux looks + makes things slightly bigger than the original MS Windows 7 thus Ubuntu is certainly my preferred choice while using this Netbook.

Installing Google Applications in Ubuntu 8 04 Hardy Heron

Google has released a number of interesting softwares for Linux platform now because all of these softwares are closed sourced :( and better free open source alternatives are available these packages are not installed by default in most of the popular Linux distributions. Also being closed source means they are not available in Official repositories too. In this article we discuss how to install these software inside Ubuntu 8.04.

Note : All the installation instructions below are for 32 bit processor .


Google Picasa 2.7

Google Picasa is one of the more user friendly photo management software available , it is available on both Windows and Linux . It runs on Linux on top of Application Layer called Wine that allows Windows application to run on Linux . However this has some disadvantage firstly some windows application dont work as well as they do on windows , there are occasional application crashes, application freezes , also UI is bit less responsive however applications are still usable .

With version 2.7 Google Picasa brings a number of interesting features not available in many free open source photo management software available on the Linux platform like integration with the Web Album , improved support for importing images from camera etc .

Now to install Google Picasa launch terminal from (Applications -> Accessories -> Terminal) and issue the following command in the terminal window:

wget http://dl.google.com/linux/deb/pool/non-free/p/picasa/picasa_2.7.3736-15_i386.deb

and

sudo dpkg -i picasa_2.7.3736-15_i386.deb

After completing above step you can launch Google picasa from (Applications -> Other -> Picasa )

Google Picasa in Action

Google Earth

Google Earth is probably one of the most popular and controversial Google application providing you with satellite view of the world to install Google Earth on your Ubuntu desktop follow the steps below.

Below we are giving link to 4.3 Beta version of google earth so it might be bit unstable if you want a stable version you can download it from this link :

wget http://dl.google.com/earth/client/current/GoogleEarthLinux.bin

and

chmod +x GoogleEarthLinux.bin

and

./GoogleEarthLinux.bin

After issuing the above command you will find a dialog box like this asking for location where to install Google Earth

After installation is over you can launch Googleearth from (Applications -> Internet -> Google Earth )

Google Earth in Action

Google Desktop

Google Desktop allows one to full text search of a users e-mail, computer files, music, photos, chat, and Web pages viewed,OpenOffice documents , PDF files and more .Now similar tools already existed on Linux like beagle (supported by Novell ) , meta tracker etc .However Google Desktop search is not based on any of these tools and uses its proprietary algorithms to search for files on the computer. So to install Google Desktop issue the following command in the terminal window:

wget http://dl.google.com/linux/deb/pool/non-free/g/google-desktop-linux/google-desktop-linux_current_i386.deb

and

sudo dpkg -i google-desktop-linux_current_i386.deb

After completing above step you can launch Google Desktop from (Applications -> Google Desktop -> Google Desktop ) initially it will take bit of your computers idle time resources as it indexes files in your computer and creates database of them. You can change setting of Google Desktop from (Applications -> Google Desktop -> Google Desktop Preferences ).

Now once you launch Google Desktop you will see a Google Desktop icon on the top right corner of the menubar at the top as shown in the screenshot below.

By rightclicking on the icon you can set various preferences , also by double left clicking the icon brings up search box allowing you to search for files among the indexed files.

How to Test Disk Drive Performance benchmarks in Ubuntu

A while ago I was quite obsessed with testing hard disk performance. I purchased a HDD those days and it was a , lets called it "A" (I dont wanna create a prejudice since this manufacture has some great products) HDD. Interestingly, one of my friends had a Samsung HDD with the same hardware specifications (RPM, capacity ...) except, the Samsung HDD had like 256Kb or more physical Disk-cache in it.

Now to this day I dont know whether it was the small Cache difference caused it... but I did noticed a little boot time delay (with MS Windows actually). I tested those both HDD in my PC and Samsung always seems to be slightly faster.

Then, since MS Windows doesnt come with a hard drive performance test or a benchmark suite in other words, I used a free utility and it actually showed that the model "A" (theyre both 80GB and IDE ones) was in fact a bit slower!.

Disk utility that comes with Ubuntu...

I went to the store and they replaced the HDD like 2-3 times but all those brand new "A" models were all a bit slower than the Samsung ones. Now as said I dont know whether the Cache on the drive that caused it... but it was clearly visible nonetheless.

So, all Im just trying to say is that, if you brought a brand-new PC then testing your hard drive performance can come in handy because it lets you compare the drives actual performance with other ones (you can find results of other drives of manufactures online easily) thus you can even ask for a replacement.

Sorry to drag you along this long... but all Im trying to say is that, having a benchmark suite can come quite handy sometimes sine it helps you to go beyond your doubts :). Anyhow, unlike with MS Windows, now if you use Ubuntu as your main OS, then did you know that even without installing any third party utility, Ubuntu has a built in tool that lets you test disk performance with ease?.

Its called Disk Utility and RedHat seems to be the developer so it might be a default app that comes with Gnome classic desktop.

Main features...

*. Test Hard disk performance.

Remember, you can only perform Write Speed tests with HDD without any file systems on them...

*. Not just HDD... you can even test your Optical Drive speed and even USB drives as well.

*. Displays other information such as File systems, partitions and their sizes, capacity, etc.

*. HDD Smart tests.

*. Format, Delete, Edit or Mount/Un-mount file systems.

You can launch this utility by pressing "Alt" + "F2" keys and put the below command and press enter (or go to: "System" -> "Administration" -> "Disk Utility" from your desktop menu as well)

palimpsest

 
Once the program is loaded, select your HDD or optical drive, etc from the list to your left and then click on the "Benchmark" button to start the tests.

But remember, it has a limitation (oh great timing Gayan! :D). That is, if your HDD is formated and has a partition table on it, then this disk test utility cannot do Write tests. It can only only perform read speed of your HDD.

It can run your HDDs Smart (Self-Monitoring, Analysis and Reporting Technology) tests too

Anyhow, even after having this limitation, still, the reason that I wrote about this utility was because, you dont have to manually install any software since its built into Ubuntu to do a basic read-test (or the complete benchmark if you have a brand-new HDD).

But there are quite a few that we can use to do advanced benchmarks in Ubuntu and Ill write about few of em in the future. If you already know about them (Im pretty sure most of you geeks know :P), youre more than welcome to share it with me dudes (+ ladies too ;-)).

Anyhow, if all you want to is just perform a basic HDD read test + access other informations such as Smart feature (which is a special function that displays "warnings" just before your HDD is about to fail so you may have enough time to backup/recover the data, etc) then you dont have to get a separate one because Ubuntu Linux comes with a one of its own and it is certainly a pretty handy utility as far as Im concerned. Good luck.

How to Split or Merge Files Easily in Ubuntu

Almost all the popular file compression tools (archive managers) have the ability to split files and then merge them later, which is also the case with Ubuntu. Thanks to the default archive manager (called File-Roller), you can split any file by using it as long as youre using a compression format that supports file splitting (.rar for instance).

But the problem of using A compression container format to split files and store them has a bit of a known risk. I think most would agree that (at least in my experience) some of these split files have a tendency to be corrupted, which is a common "headache" concerning file downloading. For instance, have you ever encountered a "CRC error" while trying to re-merge a file that was split and stored in the .rar compression format?? (errrrrrrrrrr :D).

So, to avoid or minimize these sort of difficulties we need to have a dedicated, specially designed file splitter. Although under MS Windows there a lot of free tools (HJSplit is pretty famous) available so is with GNU/Linux too!.

Its ridiculously awesome! :D...

If youd like to play with your command-line a little bit then there are few dozens available but if you want something with a GUI "attached" to it :)... that can be used under Ubuntu Linux, then Gnome Split is a utility worth trying.  Its written in Java and uses the GTK + toolkit thus integrates really well with Unity as well.

Main features...

*. Split and Merge any file.

*. 2 Times faster than the previous version according its the developers.

*. Even includes a "Wizard" for both splitting or merging.


*. Change file split using size or raw values, location, etc.

*. Use generic algorithms or different methods.

*. MD5 integrity checking.

*. Shows progress with speed, etc.


*. E-mail files afterward.

*. Enable/Disable notifications & few more settings can be accessed via the "Preferences" window.


You can install Gnome Split in Ubuntu 11.04 Natty Narwhal, 11.10 Oneiric Ocelot, 10.10 and 10.04 easily by using its PPA channel. To do that, as usual, open your terminal window and enter the below commands.

sudo add-apt-repository ppa:gnome-split-team/ppa

sudo apt-get update

sudo apt-get install gnome-split  

So, if you want to avoid most of those merging errors + looking for a extremely easy to use, features rich, fast file splitter/jointer (PDF, .PST, multimedia files or anything!) that can be used in Ubuntu (or GNU/Linux in general), then Gnome Split is certainly one of the best out there without a doubt!.

How to Split Raster Images to a PDF file in Ubuntu Linux

If you Ubuntu Linux and want to print a poster using a raster image but the image that you have will have to be split into several "pieces" before printing (which you can "attach" later of course), then PosteRazor is an extremely simple yet a very useful tool built for that exact purpose.

Its an cross-platform opesource application thus not only in GNU/Linux but you can use it in MS Windows and Mac OSX as well. Once installed youll have to load your image file and then follow its "5-step" process and then itll split your raster image and create a PDF file by using which you can easily print your poster since each page in the PDF contains a "cut" of the original image.

Main features...


*. Its written in the FLTK tool-kit thus uses its own "theming" which doesnt integrate that well under Gnome nor Qt/KDE... but as soon as it gets the job done, who cares!.

*. Once loaded, itll display information such as the raster image resolution, DPI, size and color type.

*. Supports a huge list of raster images such as: BMP, DDS, Dr. Halo, GIF, ICO, IFF, JBIG, JPEG/JIF, KOALA, LBM, Kodak PhotoCD, PCX, PBM, PGM, PNG, PPM, PhotoShop PSD, Sun RAS, TARGA, TIFF, WBMP, XBM, XPM.

*. A five step wizard type process is involved which lets you: Change the PDF pages size (A4, letter, Tabloid, etc), overlap settings, image splitting, etc.


Well, thats about it actually. When done all that, you can save the split raster image into a PDF which can be sent into printing later.

You can install PosteRazor in Ubuntu 11.04 Natty Narwhal, 11.10, 10.10 and 10.04 by using the below command in your Terminal window.

sudo apt-get install posterazor

Thats it. Good luck.

INSTALASI 3 SISTEM OPERASI DALAM 1 PC Windows xp seven dan Linux Ubuntu

Ehm ehm.. Ketemu lagi neh.. Apa kabar sahabat semuanya ? Kali neh ku mau ceritakan tentang pengalaman install 3 OS dalam 1 kompi. Yaitu windows 7, xp dan ubuntu.
Semuanya pasti da pada tau os tersebut.. Hehehe..
Oke deh, lets do it..
Untu melakukan hal tersebut install terlebih dahulu windows xp lalu win 7. Lho kok gitu? Hal ini dilakukan dengan alasan efisiensi. Karna apabila kita install win 7 kemudian xp, maka grub loader win 7 akan hilang tertimpa oleh xp, dan untuk mengembalikan grub loader tersebut, harus menggunakan program tambahan lagi, setelah itu win 7 nya di repair. Kan repot jadinya kalau kayak gitu. 2x pengerjaan.
Jadi solusinya, install win xp duluan, kemudian pada saat pembagian partisi, di buat menjadi 3 partisi. Yaitu C D dan E.
Install kan xp di partisi C, dan setelah instalasi selesai, lanjut ke instalasi win 7.
Prosedur instalasi dilakukan seperti biasa. Hanya saja instalasi dilakukan di partisi D. Tenang aja, grub loader xp tidak akan hilang oleh 7..
Naaah.. Setelah selesai., maka nantinya akan ada 2 grub loader yaitu windows earlier version ( xp ) dan win 7..
Dan tahap terakhir adalah install ubuntu nya..
Instalasi di lakukan di dalam windows nya aja menggunakan wubi. Semudah menginstall aplikasi biasa pada windows..
Dan akhirnya..
Selamat deh.. Kamu punya 3 OS dalam kompi ente..

Maaf bila terdapat kesalahan...

The following packages have unmet dependencies:
mysql-workbench-oss: Depends: python-paramiko but it is not going to be
installed
Depends: python-pexpect but it is not going to be install

5. Nah itu sudah diberi tahu gimana kita harus menginstal dependensi yang tulisanya saya tebalkan
    yaitu

apt-get -f install

    maka ke 3 dependensinya akan terinstall secara otomatis
6. Setelah dependinsinya sukses di install kita ulangi perintah ke 3

dpkg -i mysql-workbench-oss_5.2.16-1ubu910_i386.deb

7. lalu cek di aplicarion--> programming --> MySQL Workbench

Its as simple as that Installing Microsoft Fonts in Ubuntu!

From Ubuntu Blog
Installing Microsoft Fonts September 9, 2005
Posted by Carthik in ubuntu.
trackback

Even if you use OpenOffice, you might still want all the Microsoft TrueType fonts so that documents created using Word or PowerPoint look as they were supposed to when you open them with OpenOffice. Also, with the Microsoft Fonts installed we browsing will be better since the pages will look as the designer originally intended them to. Most webpages are designed with Microsoft fonts in mind. The stylesheet specify these fonts. On Linux, when these specified fonts are not available on your computer, they are replaced with generic equivalents. With these fonts installed, you will see the page as it was designed. To install the fonts, all you need to do in Ubuntu is to install the msttcorefonts package. Instructions for installation are given below.

The Truetype Microsoft fonts provided by the package include:

* Andale Mono
* Arial Black
* Arial (Bold, Italic, Bold Italic)
* Comic Sans MS (Bold)
* Courier New (Bold, Italic, Bold Italic)
* Georgia (Bold, Italic, Bold Italic)
* Impact
* Times New Roman (Bold, Italic, Bold Italic)
* Trebuchet (Bold, Italic, Bold Italic)
* Verdana (Bold, Italic, Bold Italic)
* Webdings

Installing Microsoft Truetype fonts on Ubuntu

You can install the MS core fonts by installing the msttcorefonts package. To do this, enable the “Universe” component of the repositories. This is done by default in Feisty. After you do that, use the following command from the command line:

$sudo apt-get install msttcorefonts

This will give you the core fonts, but if there are other TrueType fonts that you want installed, it is as easy as copying the font files to the ~/.fonts/ directory.

After installing new fonts, you will have to log out and log in again to be able to see and use the new fonts. If you want to avoid this, you can regenerate the fonts cache by issuing the following command:
$sudo fc-cache -fv

Sebenernya neh artikel uda lama pengen di posting, tapi belum sempat-sempat, sebenernya malas juga sih, hehehe.... alnya panjang banget, kayak si gery yang gk abis abis,, tapi mungkin tentang proxy server sudah banyak beserak di blog-blog ataupun website, tapi gak da salah nya juga kalau aku ikut serta, mana tau berguna. hhehehe.. oke deh cukup basi-basi nya.

Untuk defenisi proxy sendiri gak ku jabarkan, cuma install dan konfigurasi nya aja, kali neh ku coba dengan menggunakan mesin ubuntu 10.10 dengan asumsi sebagai berikut

Internet---MODEM—--Ubuntu server---HUB---CLIENT (192.168.0.2 s/d 192.168.0.xxx)
eth1 eth0
192.168.1.5 192.168.0.1

install terlebih dahulu squid nya
#apt-get install squid3

alasan menggunakan squid3 adalah, dalam ubuntu 10.10 tidak adanya file restart jika menggunakan squid jadi pakai squid3.

KONFIGURASI

A. Membuat NAT / Router

Agar client bisa terkoneksi dengan internet maka kita harus mengaktifkan ip forward. Hal ini bertujuan agar ppp0 atau eth0 bisa berkomunikasi dengan eth1 dan sebaliknya.

edit file /etc/sysctl.conf :

cari teks
# net.ipv4.ip_forward=1

Aktifkan dengan menghilangkan tanda “#”, menjadi :

net.ipv4.ip_forward=1

untuk meningkatan pengaman sebaiknya anti spoofing attack dan kernel map protect diaktifkan, cari teks2 dibawah ini...

# net.ipv4.conf.default.rp_filter=1

# net.ipv4.conf.all.rp_filter=1


Aktifkan dengan menghilangkan tanda “#”, menjadi:

net.ipv4.conf.default.rp_filter=1

net.ipv4.conf.all.rp_filter=1

kemudian save. Dan lakukan perintah untuk mengaktifkan konfigurasi tersebut

#sysctl -p

B. Membuat NAT dengan command iptables

#iptables -t nat -A POSTROUTING -o eth1 -j MASQUERADE

tapi lebih baik diketik script tersebut diketik di rc.local sebelum exit atau tepat diatas exit.
jika tidak diletakan di /etc/rc.local script tersebut hanya bersifat sementara, jika komputer restart, maka akan hilang.

keterangan :
-t nat adalah pembuatan tabel NAT pada iptables
-A POSTROUTING adalah menambah satu aturan baru pada bagian POSTROUTING
-j MASQUERADE adalah perintah ini akan mengarahkan rantai paket kebagian tertentu tanpa source.

Kemudian coba test ping ke client. JIka conec internet, tahap awal sukses.

C. KONFIGURASI SQUID

edit konfigurasi squid3
#nano /etc/squid3/squid.conf

cari http_port 3128
setelah ketemu hilangkan tanda pagarnya tambahkan kata transparent sehingga menjadi
http_port 3128 transparent

cari cache_mem
pada tutorial ini saya gunakan 16 MB

#Default:
cache_mem 16 MB

kemudian kita akan membuat acl (access control list) .
Cari acl to_localhost dst 127.0.0.0/8 0.0.0.0/32 ::1
dan tepat di bawahnya ketikan

acl jaringan src 192.168.0.0/24
http_access allow jaringan

2 Baris diatas digunakan untuk memberikan access control ke jaringan 192.168.0.0 selain itu maka jaringan lain tidak akan bisa terkoneksi ke jaringan luar, karna tidak diizinkan oleh squid.


Berikutnya kita akan membuat content filter

cari acl CONNECT method CONNECT
dan tepat dibawahnya kita akan membuat acl yang baru, ketikan


acl tutup dstdomain "/etc/squid3/tutup"

http_access deny tutup


Simpan konfigurasi yang telah dibuat.

Buat file yang berisi alamat-alamat situs yang akan diblokir pada directory /etc/squid3/tutup. misalnya www.facebook,com dan sebagainya.
# nano /etc/squid3/tutup
Disini saya mencontohkan facebook.com dan twitter.com

Setelah itu simpan.

Kemudian restart squid
#/etc/init.d/squid3 restart
* Restarting Squid HTTP Proxy 3.x squid3 * Creating Squid HTTP Proxy 3.x cache structure
2012/09/11 11:36:52| Creating Swap Directories
[ OK ]
naaaaah langkah terakhir adalah.....
ketikan script berikut kedalam rc.local diatas exit

iptables -t nat -A PREROUTING -p tcp -s 192.168.0.0/24 --dport 80 -j REDIRECT --to-port 3128


#nano /etc/rc.local

iptables -t nat -A PREROUTING -p tcp -s 192.168.0.0/24 --dport 80 -j REDIRECT --to-port 3128

perintah script tersebut digunakan untuk membelokan semua paket yang berasal dari port 80 ke port 3128.

simpan konfigurasi yang telah dibuat.

Reboot server / restart server
#reboot

proxy server selesai di buat....................................


Hasil tes browser dari client



thanks,,,, Untuk para master ubuntu dan salam untuk pecinta ubuntu
selamat mencoba
