fix video playback in ubuntu with x11

While running Compiz-Fusion, You wouldn’t be able to see any video play while either moving the window, viewing desktops in expo, 3d cube, or any other cool effect for that matter; instead you would see a blue screen, including when viewing in full screen.
Note:- Some of Our Users complain about the performance after using this solution.
* GStreamer Users (The default video player in Ubuntu, totem-gstreamer, and any video player that is based on the gstreamer backend)
o Open a terminal and type “gstreamer-properties”. Press Enter.
o Click the Video tab.
o Under Default Video Plugin select “X Window System (No Xv)”.
o Click Test to verify that video playback is working (you should be able to see the standard TV testing colour stripes).
o Click Close
* VLC Users (VLC is not installed by default)
o Start VLC and click on Settings, then Preferences.
o Expand Video and then expand Output modules. You will notice several options for output device.
o Select the item Output modules, and notice the checkbox at the bottom right that says Advanced options. Check the box, and now you have the option to select a different output device.
o Pick X11 video output
o Click on Save and you are set!
* MPlayer Users (Mplayer is not installed by default)
o Start Mplayer
o Right-click on the screen and select Preferences

convert virtualBox vdi to real physical bootable disk

How restore a non working windows partition and how install a proper bootloader.

Convert virtualbox .vdi to physical & bootable second disk

Actually this is very simple to accomplish. As stated before you need to unload all the drivers off of the virtual machine. get it back to the standard default drivers that came with it when you first installed the OS. This can be done a few ways but the easiest would be with sysprep (otherwise you an manually uninstall them all... never tried it this way but I suppose that it could work).

After you get it back to the factory defaults it is as simple as cloning the HDD via a program that you can boot into. My personal favourite is Hiren boot CD. I use the Norton Ghost utility off it to create a clone of the virtual HDD onto a DVD. This is accomplished by booting the virtual machine up with the Hiren CD.

With that DVD then I can boot up the physical machine with Hiren go to the Norton Ghost program and then reverse the process uploading the new image off of the DVD onto the HDD.

Overall this process takes about a hour, of course depending on the size of the virtual machine and the speed of the PC that you are using.

GNOME battery indicator thats working

On OMGbuntu I read this interesting article:
For as long as I am able to remember the Battery indicator in Ubuntu has, for me, been just shy of useless.
Whilst it pictorially displays my battery charge it hasn’t been able to provide me with anything more: all I get for enquiring further is a never-changing ‘estimating…’ menu entry.
Unsure if this was all the indicator was capable of doing I took to Twitter and asked my followers. Turns out that whilst it should tell me a bit more information than it currently many of you also see nothing but the same ‘estimating…’ menu entry.


‘Battery Status’ is a GNOME Panel applet capable of displaying  detailed information about the battery.
When run in traditional GNOME-Applet mode options such as adding time remaining or charger percentage into the icon are available.

Installing Battery-Status in Ubuntu

Open a fresh Terminal session (applications > accessories > Terminal) and enter the following two lines separately, entering your user password where prompted.
  • sudo add-apt-repository ppa:iaz/battery-status && sudo apt-get update
  • sudo apt-get install battery-status
Once the applet is installed you can then add it to the Gnome panel. Achieve this by right-clicking on the chosen panel, selecting ‘Add to Panel’ followed by ‘ Battery Applet’. Finally press ‘Add’ to place it.
When prompted choose ‘Replace’ or you will have two battery applets running.
You can move it into desired position by right-clicking directly on the applet icon and choosing ‘Move’.

Run Battery-Status as an Indicator Applet in Ubuntu

To run ‘Battery Status’ as an Indicator-applet  in Ubuntu – including in Unity 2D) – you’ll need to deploy the following command in a terminal: -
  • /usr/lib/battery-status/battery-status --indicator
To launch the indicator mode on log-in add it to your ‘Start-up applications’ in ‘System > Preferences > Startup Applications’, entering the command above in the command field.

Fix background issues in the GNOME panel

How to fix panel applet background issues in Ubuntu

Chances are if you’ve tried out a custom panel background before you’ve encountered the annoyingly artefact-y look that of the panel atop this screenshot: -
There’s a quick hack to fix it, giving you the beauty of the panel.
We’ll need to get our hands a little bit dirty for this but providing you’re careful it’s of no great effort.
This guide will assume you’re using Ambiance as your GTK theme. If you’re using a different theme substitute the path in the commands below for the correct one of your theme.
You can fix this by commenting out or removing the include
  • gksu gedit /usr/share/themes/Ambiance/gtk-2.0/gtkrc
  • Gedit will open
  • Press ALT+F to open the ‘find’ bar
  • Enter “apps/gnome-panel.rc” (sans quote marks)
  • Enter a hash (#) at the beginning of the line to ‘comment it out’.
  • Hit Save.
Note that in order for the panel background to adhere to the ‘system theme’ you will need to remove the ‘#’ from the beginning of the same line in the same file.

See recent NotifyOSD messages in ubuntu

The NotifyOSD 

in Ubuntu does a good job in providing a growl like notification bubble when new event arrive. This is useful if you are always on your computer. If you leave your PC and new notification appears and gone, you won’t be able to know that what you have missed when you return. Recent Notification is a useful applet designed to solve this problem.
Recent Notification works hand in hand with NotifyOSD. It records down all the events notified via NotifyOSD. With a single click, you will be able to view the list of all the past events.

To install in Ubuntu,
sudo add-apt-repository ppa:jconti/recent-notifications
sudo apt-get update
sudo apt-get install recent-notifications
To use it, you have to right click on the panel and select “Add to Panel” From the window that pop up, select “Recent Notification”.
You should now see a new applet in your Gnome panel.
Simply click the applet and it will show a window with all your past notifications.

Viewing, sorting and managing your notification

In addition to viewing your recent notification, you can also get it to only show notification from a particular application. For example, I have notification coming from both Pidgin and CloudSN. In the Recent Notification window, I can select from the dropdown list to get it to show only notification from CloudSN.
For each notification, you can also right click to copy the text or to blacklist the application (so that it won’t appear in the list).

Wrapping up

Recent Notification applet is simple, and useful application designed to do what the NotifyOSD can’t. It might not be suitable for everyone, especially those who hate the idea of cluttering the taskbar with yet another applet. For those who like to keep track of the notified events, this is definitely a nifty app to have. Things that I hope to see is the availability of an indicator-applet (rather than a panel applet), or better still, integrate with the messaging menu.

Batch Image Processing the Easy Way with Phatch

On Maketecheasier I read this article:
Have a bunch of photos you need to shrink? Or watermark? Or tag? Maybe add some shadows, round some corners, or stick your blog's address into the corner? We've covered batch image processing a little bit before, but for the serious image processor, GIMP might not be enough. For that, we've got Phatch – a simple, lovely, amazingly useful utility that can handle all your batch image processing needs on Linux, Windows, or Mac. Oh, and it's free.


As mentioned above, Phatch is available on all major platforms. Windows and Mac users may need to first install Python and any other missing dependencies shown on the download page, while many Linux users can find Phatch already available in their standard repositories. Ubuntu users, for example, can install with the Ubuntu Software Center or from the command line with
sudo apt-get install phatch


The standard method of working with the Phatch GUI is to start by defining all your actions. Each action (recolor, resize, watermark, etc) happens in the sequence shown in the GUI.
If, say, Blur is set above Resize, the blur effect will happen before the resize. This can be important when working with complicated sequences of actions.

Basic Conversion

The one action that cannot be skipped is the Save action. If you forget to add it to your action list, Phatch will insist upon adding it for you. This is actually a very versatile and useful action on its own, as it allows you to convert the images to various types and/or rename in one step, such as in the following example:
In that example, all the photos will be converted to optimized PNG format, moved into the ~/Desktop/phatch folder, and renamed to include the original filename plus "_phatch" to signify that they've been processed.

Chaining Actions

Phatch wouldn't be that useful if you could only apply one filter at a time. Using the + button at the top of the window, add any actions you want to apply to your images, and make sure each is set the way you want. The arrow icons at the top of the screen can be used to reorder your actions, so remember to place Save at the bottom.

Running Your Batch

If you're anything like me, you may be thinking "Ok this all makes sense… but when do I add the files to be processed?" Instead of queuing up the files then running the actions, Phatch queues up the actions and then chooses the files. Once your actions are ready, click the gear icon at the top to begin processing.
Here is where you can choose the files to include in your batch. As you can see, you've got options for different file types as well as whether or not to include subfolders. When ready, click Batch to begin a test search. You'll be shown a screen where you can verify that Phatch found all the files you wanted.
Presuming everything looks correct, hit Continue to apply all your actions.
Phatch will notify you when the work is complete, and your processed images will be found in the location specified in your Save action.


If you've got a lot of images that need a lot of work, it's hard to beat Phatch. It's functional, well-designed, multiplatform, and free. Even for those of us who know and love Gimp, Phatch has some compelling features. It may be a one-trick pony, but it's very good at that trick. Happy processing!

Fujitsu Siemens wireless / run script as root without sudo password

A friend of mine has a Fujitsu Siemens Amilo li 2727 laptop running Windows Vista.

I installed Ubuntu 10.4 LTS on this system, but alas, the wireless didn't work. This is the way I solved it:

Make a new textfile with these commands in it:

sudo modprobe -r ath5k
sudo modprobe acer_wmi
sudo modprobe ath5k 

I gave it the name

make it executable. (e.g. bij setting the rights with nautilus)

Enter ALT F2 and enter: gksu gedit /etc/sudoers  and press enter.

and in the file that opens, add to the very last line (replacing "username" with your login name):
username ALL= NOPASSWD: scriptpath
and replace scriptpath with the path to the file you want to run without a password.

for example, I want the script to run at startup as sudo without typing in the password. The last line in my file looks like:

jeroen ALL= NOPASSWD: /home/jeroen/

where "jeroen" is my user name and "/home/jeroen/" is the script i want to run.

now save the file and close it. you are now allowed to run your script as sudo without typing in a password.

so go to system > preferences > sessions and add the command you want to run at startup under "startup programs", mine looks like:
gksu /home/jeroen/wifi-on.js (replacing the path with the path to your script).

Reboot and configure your Wifi.
Reboot again and the machine should go online automatically. Even better than Windows Vista does.

Grub 2 customizer program

On How to Geek I read about this tool:

 Installing Grub Customizer

The tool in question is called Grub Customizer, created by Daniel Richter. He’s provided a PPA to make installing the tool quick and easy.
Open a terminal window (Ctrl+Alt+T or Applications > Accessories > Terminal) and type in the following commands.
sudo add-apt-repository ppa:danielrichter2007/grub-customizer
sudo apt-get update
sudo apt-get install grub-customizer
Grub Customizer will now show up in the Applications > System Tools menu.
Or you can open it from the command line.
gksudo grub-customizer

Hide Boot Menu Options

Over time, your boot menu can get cluttered with old versions of the Linux kernel. In a previous article, we showed you how to remove these manually; Grub Customizer makes this process much easier.
When Grub Customizer starts up, you’ll see a list of all the items that show up in the boot menu.
Grub Customizer_002
To hide entries that you don’t want to see anymore, simply uncheck the checkbox next to them.
Grub Customizer_004
Click the Save button at the top-left to make your changes permanent.
You can uncheck entire sections if you don’t want Grub2 to probe for new operating systems, or give you the option to test your computer’s memory.
Note that, unlike the manual method, this process does not actually remove the kernels from your computer, it just hides them from the boot menu.

Customize Grub Behavior

Grub Customizer can do much more than hide boot menu entries! Opening up the Preferences window lets you customize almost every aspect of Grub.
For example, you can set the default boot menu entry to a certain position, or a specific item.
If you’re bored by the default white-text-on-black-background look of Grub2, you can add a background image and customize text colors.
Grub Customizer - settings_006
And, for Grub2 experts, you can set advanced settings much more easily than by editing the configuration files manually.
Grub Customizer - settings_007
Grub Customizer is a great addition to any Linux installation that uses Grub2!

5 DVD Rip programs for Linux

On This site I read an article about DVD ripping. If you need the pictures, please visit the original site.

A DVD ripper software allows you to copying the content of a DVD to a hard disk drive. You transfer video on DVDs to different formats, or make a backup of DVD content, and to convert DVD video for playback on media players, streaming, and mobile phone. A few DVD rippers software can copy protected disks so that you can make discs unrestricted and region-free.

Please note that most of the following programs can rip encrypted DVDs, as long as you have libdvdcss2 installed as described here. Please check the copyright laws for your country regarding the backup of any copyright-protected DVDs and other media.

1: AcidRIP

AcidRip is an automated front end for MPlayer/Mencoder (ripping and encoding DVD tool using mplayer and mencoder) written in Perl, using Gtk2::Perl for a graphical interface. Makes encoding a DVD just one button click! 
You can install it as follows under Debian / Ubuntu Linux:

$ sudo apt-get install acidrip

On the Preview tab you can choose to watch a bit of a preview of the resulting movie:

And when you are ready, click the Start button to rip DVDs.


dvd::rip is a full featured DVD copy program written in Perl i.e. fron end for transcode and ffmpeg. It provides an easy to use but feature-rich Gtk+ GUI to control almost all aspects of the ripping and transcoding process. It uses the widely known video processing swissknife transcode and many other Open Source tools. dvd::rip itself is licensed under GPL / Perl Artistic License. 

You can install dvd::rip as follows under Debian / Ubuntu Linux:
$ sudo apt-get install dvdrip

You need to configure dvd::rip before you actually start a project. See the documentation for more information.

3: HandBrake

HandBrake is an open-source, GPL-licensed, multiplatform, multithreaded video transcoder, available for MacOS X, Linux and Windows. It can rip from any DVD or Bluray-like source such as VIDEO_TS folder, DVD image, real DVD or bluray (unencrypted -- removal of copy protection is not supported), and some .VOB, .TS and M2TS files. 
You can install HandBrake under Debian or Ubuntu Linux as follows:
$ sudo apt-get install handbrake-gtk

4: k9copy

K9copy is a KDE DVD Backup tool. It allows the copy of a DVD9 to a DVD5. It is also known as a Linux DVD shrink. It supports the following features:
  • The video stream is compressed to make the video fiton a 4.7GB recordable DVD
  • DVD Burning
  • Creation of ISO images
  • Choosing which audio and subtitle tracks are copied.
  • Title preview (video only)
  • The ability to preserve the original menus.
To install k9copy, enter:
$ sudo apt-get install k9copy

5: thoggen

thoggen is a DVD backup utility ('DVD ripper') for Linux, based on GStreamer and Gtk+ toolkit. Thoggen is designed to be easy and straight-forward to use. It attempts to hide the complexity many other transcoding tools expose and tries to offer sensible defaults that work okay for most people most of the time. It support the following features:
  • Easy to use, with a nice graphical user interface (GUI).
  • Supports title preview, picture cropping, and picture resizing.
  • Language Selection for audio track (no subtitle support yet though).
  • Encodes into Ogg/Theora video.
  • Can encode from local directory with video DVD files.
  • Based on the GStreamer multimedia framework, which makes it fairly easy to add additional encoding formats/codecs in future.
You can install thoggen as follows:

Other Tools and Back-ends

=> You need to install various libraries to use the above mentioned tools such as (yum or apt-get commands will install them automatically for you):
  • libdvdcss2 - Simple foundation for reading DVDs - runtime libraries.
  • libdvdnav4 - DVD navigation library.
  • libdvdread4 - library for reading DVDs.
=> mencoder - Personally, I use mencoder to rip my DVDs into .avi files as follows:
mencoder dvd://2 -ovc lavc -lavcopts vcodec=mpeg4:vhq:vbitrate="1200" -vf scale -zoom -xy 640 -oac mp3lame -lameopts br=128 -o /nas/videos/my-movies/example/track2.avi
Please note that AcidRip, is a graphical frontend for mencoder.
=> VLC - Yes, VLC can rip DVDs too.
=> Transcode is a suite of command line utilities for transcoding video and audio codecs, and for converting between different container formats. Transcode can decode and encode many audio and video formats. Both K9Copy and dvd::rip are a graphical frontend for transcode.

Google art

Google launched yet another interesting site: Googleart. Visit museums all over the world and look at their collection, even in 3D!

Just very very cool.

Visit their site here:  Art

Google Body

Google has something new. Google Body.

try is here:


you need a browser with a WebGL implementation:

WebGL is currently under development, and is supported in the latest builds of several browsers. Here are instructions on how to obtain a copy of a browser supporting the provisional WebGL specification. As the specification nears completion, expect that browsers will have this functionality built in to their latest releases, and not require any manual steps to enable it.


WebGL is supported in Firefox/4.0b1 and in the nightly builds of Firefox. Visit for builds on Linux (32- and 64-bit), Mac OS X and Windows.
After downloading the browser, enable WebGL: type about:config into the address bar, search for "webgl", and double-click "webgl.enabled_for_all_sites" to set it to true.
The implementation requires working OpenGL 2.1 drivers and the availability of PBuffers.
If OpenGL is not available, or for testing/debugging purposes, software rendering can be used through OSMesa (off-screen Mesa), by setting the "webgl.osmesalib" variable to point to the OSMesa shared library (typically /usr/lib/ Note that the OSMesa library is required to use "gl" prefixes, not "mgl".


WebGL is supported on Mac OS X 10.6 in the WebKit nightly builds available at .
After downloading and installing the browser, open the Terminal and type the following:
defaults write WebKitWebGLEnabled -bool YES
This command only needs to be run once. All future invocations of the browser will run with WebGL enabled.


The easiest way to test WebGL in Chrome on Windows and Mac OS X is to download the Chrome 9 Beta:
To test the most up-to-date code on Linux, Mac OS X and Windows, you can download the continuous builds of Chromium. Chromium is the Open Source project behind the Google Chrome browser.
Linux/32, Mac point to the folder containing,, or Unpack the zip archive and cd into the resulting directory. Windows has the Chrome Canary build which should just install.
Chromium must be launched from the command line in order to enable WebGL.
  • Linux: ./chrome --enable-webgl or alter the shortcut by adding --enable-webgl
  • Mac OS X: ./ --enable-webgl
  • Windows: No command line options needed.
Support for accelerated compositing is also compiled in for all three platforms. Enabling the compositor improves WebGL performance by avoiding expensive frame buffer readbacks when drawing the rendering results to the screen. Add the command line argument --enable-accelerated-compositing to test it. Note that the compositor support for WebGL is in early stages and is likely to be less stable. Please report issues you find to either the public WebGL mailing list or via the Chromium issue tracker
