Setting up awn in Ubuntu 9.10 Karmic Koala

I have a problem with Karmic Koala. I installed awn, but when I activate it, it does not work!

It was asking that a windows compositing manager be installed and suggested typing
compiz on the command line. When I typed that, compiz reported that no suitable xorg file was found, no Xgl support and that it is defaulting to the metacity window manager.

It turns out that for my ACER 4520 laptop with Nvidia 7000 card, I have to install hardware acceleration drivers for an Nvidia 7000 card, so that there will be support for Xgl. After installing it, do not fail to activate it. I also installed compiz modules via the graphical synaptic installer.

After this install, requiring a reboot, the awn dock now displays as it should.

How To Disable IPv6 In Ubuntu 9.10 Karmic Koala | UbuntuHQ

If your browsers work OK, you do not need to disable IPv6. Also, there is nothing wrong with either Ubuntu (Karmic) or IPv6, so if you are experiencing any issues, they are because of your ISP / router / modem.

Symptoms there is something wrong with your ISP / router because of IPv6 can be: Firefox works badly or Firefox works OK but Opera does not (and there is no way to disable IPv6 in Opera) or if you leave Firefox open for some time and Google works but you cannot open any other pages or to make Firefox work you have to restart your PC, etc.

The easy way: if you use Firefox, you can just disable IPv6 in Firefox. Type about:config and search for:

network.dns.disableIPv6

and toggle it to TRUE.

The ‘hard’ way: disable IPv6 system-wide: you must edit the GRUB. Be very careful, and edit it correctly or else your system might not boot!

1. Open a terminal and type the following command (if you don’t use Gedit, replace it with your text editor such as Kate, etc).

sudo gedit /etc/default/grub

2. And search for this:

GRUB_CMDLINE_LINUX

Modify it so it looks like this:

GRUB_CMDLINE_LINUX="ipv6.disable=1"

3. Now, let’s update the GRUB:

sudo update-grub2

Or if you don’t use GRUB 2, do:

sudo update-grub

4. And finally, restart your system.

The Perfect Server – Ubuntu 9.10 [ISPConfig 3]

This tutorial shows how to prepare an Ubuntu 9.10 (Karmic Koala) server for the installation of ISPConfig 3, and how to install ISPConfig 3. ISPConfig 3 is a webhosting control panel that allows you to configure the following services through a web browser: Apache web server, Postfix mail server, MySQL, MyDNS nameserver, PureFTPd, SpamAssassin, ClamAV, and many more.

Please note that this setup does not work for ISPConfig 2! It is valid for ISPConfig 3 only!

I do not issue any guarantee that this will work for you!

1 Requirements

To install such a system you will need the following:

2 Preliminary Note

In this tutorial I use the hostname server1.example.com with the IP address 192.168.0.100 and the gateway 192.168.0.1. These settings might differ for you, so you have to replace them where appropriate.

Clean Install of Ubuntu 9.10 Karmic Koala 64-bit

After upgrading to Ubuntu 9.10 using the upgrade manager from version 9.04, I started running into issues after I made some changes and was unable to boot the system.  I believed that the problem was due to several changes I had made over the last few years, I had initially started with Mythbunty 8.04 and changed several settings and configuration files.  I was going to run the Ubuntu 9.10 Live CD, but I didn’t have a lot of software or settings that I was afraid of losing so I decided to do a clean install after downloading the CD.

The first thing I needed to do was download the ISO image to get the CD for the install.  After spending hours waiting for the upgrade I was prepared to wait a few hours for the ISO, however I realized that there was an option to download from BitTorrent.  You can find the torrent information for all of the latest distributions at Ubuntu.com here. If you do not have a BitTorrent client, you will need to install one, I use LimeWire with my Vista PC and the download was complete in under a half hour.
Now that I had the image on my PC, I was able to burn it to a CD.  You will need to have burning software that is able to burn ISO’s, I like the free software ImgBurn.  Open the software, add the file from your hard drive, insert a CD and write the file.

Once the disc is complete, you are ready to install OS.  I have a dual boot, Vista/Ubuntu system, so I made sure to backup all of my Windows items just in case anything went wrong while working with the hard drive to add another OS.  The burned Ubuntu 9.10 was still in the disc drive after writing, so all I had to do was restart the system for it to load upon restart.

When the system restarts with the CD, the first thing that appeared was a request for language which was defaulted to English so I pressed Enter.  Next a box popped up asking for input on a few setup items.  Since I am the only person that uses the computer, I set it to automatically login so I wouldn’t have to enter the information at the login screen each time it starts.  The most important question is where to install the OS.

Since the system recognized another OS, it defaulted to installing Ubuntu side by side with Windows using free space to create a new partition.  You can also choose to overwrite everything so that Ubuntu is the only OS on the system, if you want to keep another OS on the system make sure that you do not use this option.  I wanted to overwrite an existing Linux distribution so I chose the advanced options, selected that partition and chose to overwrite using ext4 and selected the format checkbox to make sure it is a fresh install.  Another question that was helpful was the ability to import files from Windows including My Documents, My Music, My Pictures, and some settings which I checked boxes to allow.  Answer a few more basic setup questions and the installation will begin.

The installation took about an hour on my Core2 Quad PC, which I thought was fairly quick considering that it is an entire OS.  Once the installation is complete, the system will prompt that it needs to restart so I clicked to allow the restart.  After the restart which defaults to the Ubuntu distribution during startup, I could see the new Ubuntu 9.10 background.  The upgrade manager opened up indicating that there is software that can be updated since the time of the release, so I left everything checked and allowed them to be updated.  I also had a message about my restricted NVIDIA graphis driver needing to be updated, so I clicked on the message and selected the new driver to be installed.  Once the graphics driver is installed, another restart is required and you are ready to begin using the Ubuntu 9.10 Karmic Koala.

I feel that the clean installation was very smooth and after a short amount of time using Ubuntu 9.10, it seems to be very quick and responsive.  It was also impressed by the ability of the system to import my Windows documents, music, pictures and some settings.  If you want to do a clean install to overwrite an older version of Linux or try Linux for the first time, the process was simple and straightforward and using BitTorrent to download the ISO really helped to speed up the process.

How to recover grub2 in Ubuntu 9.10, Karmic Koala

This is a common problem you will face often. Even thought it was my first encounter with grub2 it wasn’t as simple as I expected. May be its because things are handled a bit differently in grub2 as compared to the old grub. Anyways, in this article I will tell you how to recover grub2 when you have lost it after windows installation, got some error while installing linux or somehow messed it up while changing its configuration. The below is good example.

If you have a live CD, using it boot into a live session and follow the following steps (don’t skip any unless you are know you are doing).

1) Open a terminal (Applications->accessories->terminal) and run this command

[ubuntu]$ sudo fdisk -l

2) The above command will list out the partition table of your hard disk. After identifying your linux installed partition. Run this command, I will use the partition as /dev/sda1 you will have to replace it with yours.

[ubuntu]$ sudo mount /dev/sda1 /mnt

3) If you have /boot on a different partition other then you need to mount it too. After identifying your /boot partition run this command (i am assuming it to be /dev/sda2)

[ubuntu]$ sudo mount /dev/sda2 /mnt/boot

4) Now, mount the rest of the devices

[ubuntu]$ sudo mount –bind /dev /mnt/dev/

5) Now, using chroot we will be allowed to run commands considering a specified root directory.

[ubuntu]$ sudo chroot /mnt

Now, we will be chrooted as root considering /mnt as the root directory. So, from now we won’t need sudo to execute commands as root

6) If you need to make some changes to /etc/default/grub, open the file in your favourite editor ( i will use vim)

[root]$ vi /etc/default/grub

7) Make whatever changes you want to make and run update-grub to create the configuration file.

[root]$ update-grub

8) If you want to install grub2 to MBR run this command.

[root]$ grub-install /dev/sda

If you want to install it to some partition then use that partition name instead of /dev/sda e.g. /dev/sda1 for the second partition etc. Or if you want to install grub2 on another drive then you may use that name e.g. /dev/sdb for an external hard disk.

You will have to resolve the names using fdisk -l command. (be careful while doing that)

9) If you faced some error while installing grub2 then you may want to run it with –recheck attribute.

[root]$ grub-install –recheck /dev/sda

10) Once you are done with this either press Ctrl-D to exit chroot or type exit.

11) And then umount the partition you have mounted starting from /dev

[ubuntu]$ sudo umount /mnt/dev

[ubuntu]$ sudo umount /mnt

Another Ubuntu 9.10 Karmic Koala Review

I know there are quite a few reviews of the very-soon-to-be-released version of Ubuntu called Karmic Koala or 9.10, but I wanted to share my impressions too. Another can’t do any harm can it?

I’ve had the Karmic development release running since Alpha 2. I started with it because it supported some newer hardware on the Asus 1008HA netbook and that machine is not as critical as my desktop is for work so I could afford for it to go wrong occasionally. Although it has been only very occasionally.

The first thing is to say how much it has changed, for the better, from Alpha 2 to where we are now – less than 2 weeks before release. There were the very obvious cosmetic changes, new applications and changes underneath such as to the boot up process. It’s fascinating to watch and quite a nice surprise when you do your daily, or sometime less frequent, updates to see things change and develop so rapidly. Having a 150MB update day was not uncommon. I reported a few bugs along the way and hopefully have helped to improve the end result that will be available for anyone to download for free on the 29th October.

My Karmic DesktopMy Karmic Desktop

Sometimes I feel that I take Ubuntu and other FOSS for granted, but then wake up and slap myself around the face. It’s bloody amazing. Anyone, anywhere, can download this or many other complete PC operating systems. These are modern, reliable, secure and FUN to use; and come with application software too. On the 22nd October another PC operating system becomes available that is NONE of those things and you have to pay for it! I’d like to thank and applaud everyone who has touched Ubuntu or any other Free and Open Source software in however a humble way it may be. We are all bloody amazing frankly.

Back to Karmic then. Having been using it on-and-off for a couple of months now my overall impression is Very Polished indeed. It looks the dogs bollocks compared to previous releases, the subtle changes to the Human Theme and colour scheme are really good. The new icon set looks very modern and the system boots a bit quicker and shuts down in a flash! It is quicker on my netbook to shut it down and reboot than to use hibernate. Which is actually a good thing as the suspend/hibernate doesn’t work too well on this netbook currently.[UPDATE] I was just discussing Karmic with some of the peeps on the #ubuntu-uk IRC channel and I tested suspend and hibernate again. This time they both worked. It still seems to take a bit longer for hibernate to resume than a clean boot but there’s not much in it.[END UPDATE]

Ubuntu Software CentreUbuntu Software Centre

For the new stuff, there’s the Ubuntu Software Centre which is now spelled correctly for a UK English locale, there’s Empathy which I think I will get to like, Firefox is now the 3.5 release and OpenOffice.org is on 3.1 which means we have the Open GL Transitions back.

On Jaunty I have been using Gwibber 1 for some time and it’s a nice simple application that, for the most part works well and does its job. On Karmic, Gwibber has been updated to version 2 and I have to say that in my opinion version 2 of Gwibber is a complete regression. The UI is far to intrusive, and it all takes up much to much screen real estate.

The last five screenshots (below) are of Gwibber. The first one, is the “welcome screen” that I seem to be presented with every time it starts, whether I want it or not. I do not. In the second image I am trying to show the size of the font and the amount of wasted space per message. Even though there is an option to change the font size, that doesn’t work at the time of writing this. The third image is what happens when you want to reply to, or RT, a message; except the edit box is not immediately visible. You have to guess that it is under the drop down that has just appeared and then slide the area up; each and every time. The next shows the account navigation pane which I find to be rather pointless and it just gets in the way. And finally, Gwibber crashed whilst I was taking screenshots when I was trying to open a configuration dialogue box. I’ve filed a bug.

Other than Gwibber 2, which I feel is a real backward step, the rest of Karmic is really great. It looks brilliant and modern. It works smoothly and quickly. Some of the new features like the Ubuntu Software Centre, Empathy and Indicator Applet are really well thought through and add positively to the whole experience. It’s been reliable, my 3G dongle just worksTM, as did the speakers, microphone and webcam.

Here’s a selection of snapshots taken on my netbook to give you more of a flavour of what it looks like. The only change I’ve made from the the default is the desktop image, although this one is from the set that is supplied with Karmic Koala.

Karmic Koala is Brilliant. It is a major update to Ubuntu. The new look and feel is really great. I doubt it will be changing much more before release but as always I should probably add a YMMV here.

If you are using Jaunty or earlier on your desktop, I’d recommend that you give this release a try. If you are thinking about coughing up hard-earned money for that other operating system that is coming out this month, don’t. You’ll be wasting your cash and be getting a less secure, less functional, more resource hungry and just plain worse OS to boot! And do remember I’m still using the Beta version of Ubuntu. The GA release will be out on the 29th Oct.

If you can’t wait you can download the beta from here. This beta won’t expire either
