DesktopNova : Automatically Change Wallpapers in Ubuntu 11.04

I’ve been using the Ubuntu 11.04 for quite some time now. Compared to the previous versions, various changes have been made in Ubuntu like the Unity interface became the default UI for Gnome, Banshee replaced RhythmBox as the default media player, OpenOffice.org was replaced with LibreOffice, etc. This enabled me to easily switch from Windows to Ubuntu. I could easily find replacements for most of the applications I used in Windows. But, one Windows feature I still miss is automatically changing wallpapers.

DesktopNova

Automatically changing wallpapers or slideshow wallpapers gives your desktop a completely new level of personalization. Well, after Googling for a while I found that by using an application called DesktopNova you can easily create changing wallpapers in Ubuntu. DesktopNova is a simple application for Ubuntu that automatically changes your desktop wallpaper after a preset period of time. This application works only on Gnome and Xfce desktops. In this post, I will show you how to install and use DesktopNova in Ubuntu 11.04.

Installing DesktopNova

To install DestopNova, click on Applications in your Unity launcher menu and search for Terminal. If you are using the classic Gnome interface, you can open up the terminal by going to Applications -> Accessories -> Terminal.

Ubuntu Terminal

In the Terminal window, type the following command to download and install DesktopNova.

sudo apt-get install desktopnova desktopnova-tray desktopnova-module-gnome

Install DesktopNova

Once the installation is done, you will have to configure the application so that it can work with your desktop.

Configuring DesktopNova

To open the DesktopNova configuration tool, click on Applications in your Unity launcher menu and search for DesktopNova. Classic Gnome users can just go to Applications -> Accessories -> DesktopNova.

DesktopNova

First, you will have to add the images that you want to use in rotation. To add images one-by-one simply click on the Add button. To add directories, click on Add Folder button and select the directory that contains the wallpapers.

DesktopNova Configuration

Once you have added the images you need, go to the Settings tab. Under Settings, tick the checkbox next to Change wallpaper in intervals and enter how frequently you would like DesktopNova to change the wallpaper. Also tick the checkbox next to Change wallpaper every launch and Launch daemon every session(Autorun) so that DesktopNova automatically starts every time you start your system or even change your session.

DesktopNova Settings

Now, to activate DesktopNova on your desktop, click on Modules, select Gnome 0.2 and hit the OK button.

DektopNova Module

Next, go to the Tray-Icon tab and tick the checkbox next to Launch tray-icon every session(Autorun). This makes sure that the DesktopNova tray icon launches automatically when you log in. The tray icon enables you to manually change wallpapers as and when required. Finally, hit the Save Settings button at the bottom. This completes the configuration of DesktopNova.

To start DesktopNova, go to the Settings tab and hit the Start Daemon button.

Start Daemon

This starts the daemon that works in the background and automatically changes your wallpaper. To start the tray icon, just log out and log back into your account. You can manually change your background by right-clicking on the tray icon.

How to Fix iTunes Error 1015

The process of upgrading your iOS device to a custom firmware or downgrading to one that isn’t supported by your version of iTunes always comes with errors. There are so many errors that one will encounter when doing an upgrade or a restore, but the most common one would be the 1015 error on iPhone. I’m about to explain to you a really simple trick on how to fix 1015 error in iTunes.

Error 1015

The 1015 error pertains to the recovery loop experienced by iOS device users when upgrading to a custom firmware, specially the older ones such as iOS 4.1, iOS 4.2.1 and so on. This happens when you’re trying to restore to an iOS version that your version of iTunes doesn’t recognize, or when there’s a conflict with the firmware itself. Your iOS device, thus goes in to a recovery loop, where it isn’t able to exit it. This normally leaves the user in a state of paranoia and this message from iTunes;

The iphone “iphone” could not be restored. An unknown error occurred (1015)

however, you don’t need to worry because it’s not as bad as you think.

Fixing Error 1015 in iTunes: Recboot

Here’s a simple trick on how to fix 1015 error in iTunes that doesn’t require much time. All you have to do is download and install a free software known as Recboot, use it to get your iOS device out of recovery mode and voila.

  • Download Recboot for Windows and Mac.
  • Make sure your device is connected to the computer and iTunes is running.
  • Run Recboot and select Exit Recovery Mode.
Recboot
  • Only select Exit Recovery mode if your iOS device is stuck in Recovery loop and is doing nothing or showing error 1015 in iTunes.
That’s it. You’re now out of the Recovery mode and the iOS device should reboot. You’ll then be treated with an activation screen, but if you’ve used a custom firmware or have already jailbroken it, then you’ll  be taken straight to the homescreen. And that is how to fix 1015 error in iTunes!

How to Configure Belkin N150 Modem router with Airtel Broadband Connection

Just not we finished publishing unboxing pictures of Belkin N150 wireless modem-router and here is a quick guide for those who are trying to configure their Belkin N150 modem-router with Airtel broadband connection.

I bought this device from Thailand and it comes with a handy template which shows the settings of popular broadband connection in most of Asian countries, so you can use the same guide to configure it for Reliance, BSNL or MTNL connection too.

Here is an image for your reference, so if you configuring router-modem for BSNL, Reliance or MTNL connection, it would be handy for you.

Getting started with Belkin N150 Modem-Router With Airtel Broadband connection:

Airtel Broadband settings:

You need to have your broadband login and password. Login is usually your landline number with STD code followed by [email protected] For ex: [email protected]

And your password would be: your account number. Which you can get it from your Airtel broadband bill at the top. You can also get your account number by login into your current Airtel modem by typing: 192.168.1.1 in your web browser field, and try login in with default username and password, i.e:

  • username: admin
  • password: password

If you have forgotten your Airtel modem password, you can try password as your account number which can be retrieved from your Airtel broadband bill.

Apart from this, there are 3 settings which you need to remember:

  • Connection type: PPP0E
  • VPI/VCI: 1/32

Connecting your Belkin router:

Connect your Belkin modem-router with power connector and in ADSL line, plug in your Airtel ADSL cable.

Now, you can either connect to router from laptop using Wi-Fi or by Lan cable. I simply connected using Lan cable, by default it picked the I.P from DHCP.

Setting up Airtel broadband:

Now, open 192.168.2.1 in your web browser, it will prompt for password, and if you have not changed your Belkin router password, simply hit next.

On the next field, it will ask you to enter the connection type as shown in below image, select PPP0E and click Next:

Enter your Airtel broadband credentials, as I have mentioned above. So your final output would look something like this:

Belkin-Airtel-Config

Click on Next/Save and it will restart your router. It might take 60 seconds, so be patient. Once your router is restarted, the light on your modem-router will turn green and it indicates that you are connected to internet.

Alternatively, Airtel also suggest you to add the DNS field manually, though I leave it as default and use Automatically from ISP. Though if you wish to add Airtel DNS, you can add these DNS:

202.56.215.54
202.56.215.55

Airtel DNS

Now, enjoy your new modem-router configured with Airtel broadband connection. Do let us know if you have any questions setting up Airtel broadband connection, with Belkin router.

How to Transcode video Using VLC Player

This is a feature that I really liked about VLC, because in normal media players you don’t find option like converting videos from one format to another. VLC media player can be used to rip disc-based multimedia contents like music or videos, plus it can be used to convert videos from one format to another.

Rip-Convert-with-VLC-Player

To use VLC player as a video converter, start VLC and click on Media and then Convert/save option. A dialogue box will pop-up that will allow you to choose that either you want to convert or rip and then where you want the destination file to be. Once you are done adding the source media click on Convert/Save to start off with the process.

After that another window will pop-up that will allow you to choose that all the encoding settings such as output location of file and codecs. Normally transcoding is a resource-intensive process so you will have to be a bit patient.

Do try out these amazing feature on your VLC player and let us know in comments that what do you think about them?

How to Create Multi-Part Compressed Archives Using WinRar

Some files are simply too large to email or send through the internet. For these we use file compression programs that size down these large files. However there are times when even the compressed file is too large to be transported through the internet. The solution then becomes multi-part compression: compressing the original file by breaking it down into numerous parts. Specially if you download movies from Torrent or any other file sharing site, you will notice that many time a big movie file is broken into small files and compressed using win-rar.

There are a number of free programs available e.g 7-Zip etc, that perform multi-part compression. But the most user friendly is WinRar. You can get WinRar to compress files into smaller parts by following these easy steps:

Step 1:

Download and install WinRar from here.

Step 2:

With the program installed you click on any folder or file and compress it. Right-click on the file, enter the 7Zip menu, and select “Add to archive.”

winrar-1

Step 3:

Using the window that opens up, you can control various aspects of the output archive. Start by specifying the output format and the size of each part of the multi-part archive.

winrar-2

Confirm your options and start the compression. Wait patiently while the file is compressed – the larger the file, the more time it will take for compression.

Step 4:

With the compression finished, verify the result by trying to uncompress the multi-part archive. This step is not necessary but serves as a good practice to make sure the archive turned out perfectly.

winrar-3

And that is all. The 4 easy steps mentioned above can also be followed using numerous other free compression software such as 7-Zip as well. If you have any other compression software installed, explore its options and see how it lets you create multi-part compressed archives.

Download WinRar

Do let us know which software are you using to compress your file? Are you using WinRar, 7Zip, WinZip or any other software?
