How to install rmagick extension to ruby on Ubuntu ?

That's a very good question as the rubygems embedded in the debian package is a limited edition where you are not able to make an "update --system".

So first thing to do:

 sudo apt-get remove rubygems

Then, from www.rubyonrails.com, follow the rubygems installation tutorial:
- download the archive delivered from rubyforge,
- tar -zxvf rubygems-1.3.1.tgz

and:
 cd /rubygems-1.3.1
 sudo ruby setup.rb

and follow with a :
 sudo gem update --system

OK, rubygems is now up to date.

Go on installation of rmagick:

 sudo apt-get install ruby1.8-dev
 sudo apt-get install g++ automake autoconf
 sudo apt-get install libmagick++10
 sudo apt-get install libmagick++9-dev
 sudo gem install rmagick

and then you will get the following console output:

frederic@nostromo2:~/Logiciels/development/ruby/rubygems-1.3.1$ sudo gem install rmagick
Building native extensions.  This could take a while...
Successfully installed rmagick-2.9.0
1 gem installed

And now, you will be able to use the Rails plugin named file_column; cd into your rails project:
 cd myprojectsrails

 script/plugin install http://opensvn.csie.org/rails_file_column/plugins/file_column/trunk


And enjoy !

Ubuntu 8.10 on EeePC 900 : easy mode !

Note:
First thing to get it working is to be sure you will be able to connect your netbook to ethernet in wire mode.

----

Installation of Ubuntu 8.10 Live on a USB key.

The best way to do rule this part is to use the famous UnetBootIn. this tool will allow you to install easily your prefered Linux Distro, here we will choose Ubuntu 8.10 live, on a USB key. Please choose a 1Gb sized k

The best way to do rule this part is to use the famous UnetBootIn. this tool will allow you to install easily your prefered Linux Distro, here we will choose Ubuntu 8.10 live, on a USB key. Please choose a 1Gb sized key to be quiet.

So just download unetbootin (twin versions exists : a windows and a linux version), and run it. If you are on Linux, you will be asked to install another debian package containing 7z. You will find a page on the official french Ubuntu site, on in the Ubuntu-eee site explaining how to use it.

EeePC 900: get it work !

Now the easiest part of this how-to: install Ubuntu 8.10 on your EeePC. Just click on the Install icon the Desk after booting on just prepared before USB Key. To boot on it, push the ESC key and choose the USB Device, while your Eee PC is just switch on and you get the grey screen with the EeePC logo.

After installing this, connect your Ethernet wire and update your just installed Ubuntu. now you are ready to customize your netbook OS accordingly to the EeePC capacities (Wifi, CPU frequency tools, Energy saving, etc...)

Wifi

We will have 2 steps to do:

  1. - remove existing ATH modules
  2. - install backported from Hardy Heron the ath5k module.

Remove the existing modules:

sudo modprobe -r ath_pci
sudo modprobe -r ath_hal

Add to the balck list these 2 modules:

edit the file /etc/modprobe.d/blacklist and add the 2 following lines at the end:

blacklist ath_pci
blacklist ath_hal

Connect to the internet through ethernet (get wired !) and backport modules from Hardy Heron:

sudo apt-get install linux-backports-modules-intrepid-generic

Now, just reboot, and you will get the wifi running, and will be able to configure your wireless connection via NetworkManager.

CPU frequency managing

To activate the cpu frequency selector, you will have to install the following:

sudo apt-get install gnome-cpufreq-selector

And now edit /etc/modules and add this line at the end:

load p4-clockmod

Energy Saving

To enable the cpu frequency adaptor following energy mode, you will have to modify registry with gconf-editor.

dpkg --reconfigure gnome-applets

powertop will could easily help you reducing energy consumption by analyzing actual energy wasts and give you useful tips on how to save.

sudo apt-get install powertop

For more information on the Gnome Power management, see this page.

And that's all folk !

to be continued ....

Three new tools on my EeePC 900

Micro blogging, updated sites detection, and fast launching anything on my netbook running Ubuntu eee 8.04.1  is what is now possible thank to the following fabulous tools:

Gwibber

It's a webkit based poster for any blog/twitter/facebook platform. Well rendered, the tool use the apple opensourced version of webkit, the HTML renderer. with a userfriendly interface, anybody can now feed its muti sourced blogs and be advertized when a known and wel configured site was updated.

Specto

It's an old tool, but nothing replace this llittle thing which permit you tobe informed when a site was updated, giving a little mesage from the gnome panel that the site John Doe was updated.

Gnome-Do

the faster way to start anything on your laptop ! Just push the "super"+"space" combination keys and you'll just have to input some first letters of what you want to do, "facebook" for exemple will open your bookmark from firefox or epiphany to te facebook site, "text" will route you to the "OpenOffice Text writer" and if more than one item respond to your input, a list will appear pressing "down key", and then, just hit the "enter" or "return" key and that's all !

[edit] Add the --mini parameter to the gnome-do command and you'll get a well netbook feated UI !  great, thanks to Alex for the tips.

Thanks to opensource software to solve all these every day life problems ;)

EeePC + Ubuntu + Locked session

Since I've installed Ubuntu-eee on my EeePc 900, i've notice a strange behaviour of the X server. Each time I locked my session, i was unable to unlock it with my right password while I could connect on a new session...  

Digging the google ground (the net...) i found this post that save myself and my eeepc (an my mind sanity :)


All the problem rely on a simple file permission issue !

Just correct the file permission of the unix_chkpwd command with the following command lines:

chown root:shadow /sbin/unix_chkpwd
chmod 2755 /sbin/unix_chkpwd

That's all.

Thanks to michaelkahl whose solve the problem.
