There’s nothing wrong with the default brownish “Human” Ubuntu login screen, but sometimes your brain might get bored with the same login screen overtime. So in this post I’ll be showing you how to randomize the GDM login screen through these simple steps :
From Desktop, go to System->Administration->Login Window
Choose “Random from Selected” from the selector in the Login Window dialog. And check all the GDM themes that you wish to be cycled each start up.
That’s it! close the dialog and logout from your GNOME session, it should display random login screens each time when you switch on your computer.
Need more themes?
You can always find and install more cool themes from Gnome Looks !
I’ve always wanted to try and take panoramic photographs using my dad’s Nikon Coolpix 5200. That day finally arrived when I finally have the free time to do so last week when I’ve to accompany my dad traveling to the countryside of my hometown.
Using a tripod, I took 4 sets of photographs with the help of Nikon built-in panorama helper function. I was excited and about to use a Windows computer to stitch those photograph using software supplied with the camera when suddenly I thought of searching for a similar application on my trusty Ubuntu box.
To my delight I found Hugin! An open source panorama maker software which I use without hesitation to create a my first ever panoramic photos.
The interface was simple enough to use even for a first time use like me. What you need to do is to load all images into Hugin using the “Load Images” button, and it will start to process your images immediately.
After finished processing the photos, Hugin lets you fine tune the result using a dialog similar like below.
After retouching and minor adjustment, I’ve ended with this panoramic photo!
p/s: Well the photo is not perfect in detail, but hey its my first try!
Previously I’ve written a post about how to send/receive file over the bluetooth using CLI. Now i’m going to show you a quick way to send files over bluetooth using the standard “Send To” on GNOME. Like this
To enable this, you need :
- gnome-bluetooth (available from the repository)
- a Bluetooth dongle / device attached to your computer
After all requirements have been met, all you need to do is select the files which you wish to be send over bluetooth, and click “Send To”.
You should see a dialog similar like above, prompting you to select the desired bluetooth device.
It’s easy with Linux!
A friend from #fakap asks me to create a dead simple FLV to 3gp batch converter for him to port youtube clips to mobile phone.
As a result I complied, and created flvto3gp bash script for the job.
Using it is simple, just run this script inside a directory full of FLV (or any video files supported by ffmpeg) and execute it using this command :
sh flvto3gp.sh *
The script will convert all video files to 3gp file format one by one. The script requires
ffmpeg in order to run.
Ubuntu users might have to refer to this post before using this utility : Enable mp3 and amr support in ffmpeg ( Ubuntu )
