I have been using Ubuntu 9.10 for a while now and one major copy-paste problem in Ubuntu (GNOME DE) struck me!!

The problem is, if you copy some text from a file and you close that file (i.e. close the source), the copied text also disappears! Initially I ignored the problem, but after a while, I had it! It was really very annoying if you copied some important link and you close Firefox, the link was lost!

When I went out and searched for the problem then I found this, the actual bug report on the Ubuntu Bug Tracker. According to the Canonical guys, it is a system feature of the X-Windows System, as per its design, it does not have any persistent store mechanism and that sucks! (Here are the X-windows Clipboard manager specifications which is presently deployed on Ubuntu 9.10)

That means, the primary problem is with the X-Windows System and I hope this flaw is sorted out in Ubuntu’s next LTS release, The Lucid Lynx.

So the question is, how do you solve this problem for now?! I have the solution :)

The solution to this problem is to install Glipper, a clipboard manager for GNOME. You can simple install it from the terminal:

sudo apt-get install glipper

This will replace your current clipboard manager and it works perfectly!

So, that will solve your problem of the missing copy in Ubuntu GNOME! ;) Similar Posts:

You can merge your GNOME desktop (Ubuntu 9.10) with Google Calendar via iCalendar Format. This a very nifty hack for people who use Google Calendar and want your Linux to in sync with Google Calendar.

What is iCalendar?

XML or iCalendar – Use these formats to view a read-only version of your calendar from other applications. You can use this address to access your calendar from feed readers (like Google Reader) as well as products that support the iCalendar format (like Apple’s iCal). via Google Support

1. Go to your Google Calendar and select the down arrow with calendar you want to sync with GNOME and select Calendar Setting

2. Copy the link of the Green button, iCal next to Private Address.

3. Now, open the linux Terminal and type the following:

/usr/lib/evolution-webcal/evolution-webcal URL_YOU_COPIED

That’s it! You will see an appointments option under the GNOME clock.

If you a windows “power” user, a shift to linux will be really good, but it also comes with little packages of frustration sometimes.

I was trying to install JBOSS 4.3.2 (which was very smooth) and trying to run a JMS application. This is a very easy task in Windows, but since, I am new to linux, some easy tasks became so annoying!!! But later I realized it was much simpler once you get the hang of it. So, here are the steps to run a JMS application on Linux (Ubuntu 9.10)

1. Install JBOSS 4.3.2

Download JBOSS 4.3.2 to your desktop and extract the tar.gz or zip file ot /opt folder in the main file system.

“sudo unzip boss-4.2.3.GA-jdk6.zip /opt“

And you are done with your JBOSS installation!!

Go to your terminal and type “sudo /opt/jboss-4.2.3.GA/bin/run.sh“. This will start you JBOSS server in 20-25 seconds.

2. Configure the environment variable in linux

This was the most annoying part for me since I didn’t know how to set the environment variable in Linux. Though its a very very easy process!

Execute this following code in the terminal:

export CLASSPATH=$CLASSPATH:/CLASSPATH=/opt/jboss-4.2.3.GA/client/jbossall-client.jar
To check if you have set the CLASSPATH correctly, type echo $CLASSPATH and if you see the following, you see this, you have set your classpath correctly!

:/CLASSPATH=/opt/jboss-4.2.3.GA/client/jbossall-client.jar

3. Configure your JMS code (more example) (depends on your code)

Go to Eclipse IDE and import your JMS Code. The most simple code should contain 2 files, a client and a server. Then right click on the project > Build Path > Add External Archives; then browse to the folder where you installed JBOSS, (/opt/jboss-4.2.3.GA/) in our case and then go to client folder and add jbossall-client.jar

/opt/jboss-4.2.3.GA/client/jbossall-client.jar

You are all set to run your first JMS application!

You need to create a topic or queue to run the server, for this start the JBOSS server using:

sudo /opt/jboss-4.2.3.GA/bin/run.sh

  1. Go to http://localhost:8080 in your browser.
  2. Go to JMX console
  3. Scroll down to jboss.mq and click on service=DestinationManager
  4. Scroll down to  createTopic() method; type in the topic name you want to create and click “invoke”

4. Integrate JBOSS with Eclipse Ganymede using JBOSS Tools (optional)

If you want to start and stop the JBOSS server from your Eclipse installation then add the JBOSS Tools to eclipse in Help > Software Updates. You can follow the steps given in this tutorial.

Syncing iPod/iTouc/iPhone with Linux is a major headache!

UPDATE: Rhythmbox works out of of the box with iPod, check here

I tried many softwares; the so called iTunes alternatives, but none of them actually work!

The one guaranteed way to sync iPod with iTunes on Linux (Ubuntu 9.10, 32bit) is by using VirtualBox and tweaking your Linux box.

What I am using?

  1. Ubuntu 9.10, 32bit
  2. Virtual Box 3.0.10
  3. Windows Server 2003 (You can also use Windows XP SP2, I haven’t testing it, but it should work.)
  4. iTouch 2nd Gen with iTouch OS 3.1

This tutorial guides through the complete process, its simple and easy, but this tutorial is for old versions of VB and Ubuntu. You don’t need to follow the last few stages of the guide. SO, the revised stages are:

  1. Install Virtualbox

  2. Configure the USB support

  3. You don’t need to recompile the kernel USB support as mentioned in the tutorial.

  4. Connect iPod Touch to Windows XP VM

And you are done, if everything goes well, you will be able to see you iPod in your iTunes.


UPDATE – WITHOUT USING VIRTUAL BOX

Linux and Your iPhone / iPod Touch using iFush and libiphone-utils libraries.Similar Posts:

Ubuntu is one of the most common distros of Linux available. With its latest release Ubuntu 9.10, Canonical has added new features, including:

  1. The Ubuntu Cloud platform, Ubuntu One,
  2. A better boot speed and UI,
  3. One of the most awaited feature, Ubuntu Software Center, more on the lines of Windows Add/Remove program.

There are many more feature updates in Karmic Koala, you can find them here.

I don’t understand why Pidgin was removed as the default messenger and replaced with Empathy. This might be a result of one of the ideas put up on Ubuntu Brainstorm site.

The Upgrade from Ubuntu 9.04

The upgrade was pretty straight forward using the Upgrade Manager (System > Administration > Upgrade Manager) in Ubuntu. Find the detailed steps to upgrade from Ubuntu 9.04, Jaunty Jackalope to 9.10, Karmic Koala here.

The login splash screen has changed in 9.10, though my personal favourite was the login screen in 9.04.

Ubuntu One

Ubuntu One is service enables users to store and sync files online and between computers. Its same as DropBox. Though Ubuntu One is still in its infancy and has a long way to go, I got an internal server error once on the Ubuntu One site and sometimes the Ubuntu One client on my machine does not connect, so for the time being, I am sticking to DropBox.

If you are planning to upgrade, here are the minimum system requirements:

  • 300-MHz x86 processor
  • 64MB RAM
  • At least 4GB of disk space (for full installation and swap space)
  • VGA graphics card capable of 640-by-480 resolution
  • CD-ROM drive or network card

Conclusion: Upgrading is worth it.

UPDATE

People are complaining about slow boot time in 9.10 as compared to 9.04, you can solve that problem by the solution posted here

sudo add-apt-repository ppa:ubuntu-boot/ppa
sudo apt-get update
sudo apt-get dist-upgrade

This should install an updated kernel package, and replace sreadahead with ureadahead.

The first reboot will reprofile your system, the second reboot should be substantially faster.

Please let me know how you get in (before/after bootcharts always appreciated)
