In this post we will see how to add an application in start-up so that it automatically starts each time you login in to Ubuntu.
Go to Unity or Gnome dash and look for Main Menu:
How to solve: No Wireless Network Detected in Ubuntu 11.10
One of the most common problem one faces after a fresh install of Ubuntu is the loss of Wireless Network. And believe me that is the biggest pain for a normal user. The problem double-folds if the wireless adapter is broadcom (do not know what is your wireless adapter? click here). Some of the general problems are showing no wireless adapter, showing wireless adapter but detecting no wireless networks etc. [Read more…]

Make Windows default OS in dual boot with Ubuntu: The easy Way
When you install Ubuntu (or any other Linux OS), it makes Ubuntu the default operating system. So if you want to use Windows, you have to select it manually within 10 sec otherwise it boots into Ubuntu directly.
But what if you are not a regular Ubuntu user (Why so?) and use Windows most of the time? It irritates you that you have to wait at each boot to select Windows. If you are facing such problems then you might want to make Windows your default operating system so that it boots into Windows by default. [Read more…]
How To Install Gnome 3 in Ubuntu 11.10
April 2011 saw a change in Ubuntu where it launched Unity instead of Gnome as its default desktop environment. That did not went down well with many users who wanted to use the newly launched Gnome 3 in Ubuntu. Ubuntu 11.04 did not provide support to Gnome 3 officially. Enthusiast users did find a way to install Gnome 3 though but it resulted in breaking the Unity environment completely which means that a user could have used either Unity or Gnome 3 not both.

How to solve: Keyring problems in Ubuntu
What is Keyring?
A Keyring (in Ubuntu) as its name suggests is collection of keys (passwords) and is locked by a master password (be default your first admin password). It saves several passwords (for e.g. login password for a website or some application) inside the keyring and protects with the master password and thus obviates the need of entering the passwords again and again. Since you are logged in with the same password, it does not prompt you to enter the master password and automatically takes the login password as the keyring master password.
What could be the problem with the Keyring?
As I said before the default master password for the keyring is the first admin password i.e. the first user-password you used on the computer. The problem arises when you change the password. The master password of the keyring doesn’t change automatically and hence a conflict starts as the master password doesn’t matches with the new user-login password. Therefore you will start seeing these annoying prompts from the keyring:
And if the password doesn’t matches then:
Solution 1: You remember the old password
If you remember the old password then you can try changing the master password to the current login password. This will stop the prompting of the keyring. Follow these steps in Ubuntu 10.10 and previous versions:
- Navigate to Applications > Accessories > Passwords and Encryption Keys
- Select the tab “Passwords”
- Select your keyring
- Right-click and select “Change Password”
In Ubuntu 11.04, run the application Passwords and Encryption Keys by using the super key (windows logo key) and then searching for it. And follow the step 2-4.
Solution 2: You forgot the old password
Damn! I forgot the old password and it is not accepting any of my login passwords. What should I do? Don’t bang your head in the wall. There is an alternate solution and that is delete the keyring. For that follow the same steps 1-3 as described previously and instead of Change Password select Delete. i.e.The following steps:
- Navigate to Applications > Accessories > Passwords and Encryption Keys
- Select the tab “Passwords”
- Select your keyring
- Right-click and select “Delete“

How to change the default boot order in Grub 2 in Ubuntu 10.04, 10.10 and 11.04
In this tutorial we will see how to change the default boot order in the Grub 2. Grub 2 is the default boot loader in Ubuntu 9.10, 10.04, 10.10 and 11.04. As the computer starts, GRUB 2 either presents a menu and awaits user input or automatically transfers control to an operating system kernel.
There are two ways to do it. Experienced user can do it by editing the Grub file (located in /etc/default/grub) while I will recommend the beginners to use a GUI tool (Startup Manager) which lets the user select the default operating system or kernel. The tutorial on the Startup Manager can be found here.
Step 1:
Take a look at the boot order in the Grub (when the computer start). Note down the order. Let us assume this is how the boot order arranged:
Linux Kernel 3.0 ——— 0
Linux Kernel 3.0 Recovery Mode ——— 1
Previous Kernel Versions ———- 2
Previous Kernel Versions Recovery Mode ———- 3
Memory Test ———- 4
Memory Test Recovery ———- 5
Windows 7 ———- 6
Notice the numbers we assigned to the orders. The numbers represent the position of the particular os/kernel (starting from 0).
Note:
What if you want to make a previous Linux version as your default. The previous Linux Version may consists of all the previous Linux Kernels. Grub 2 provides a nested style sub menu. The previous Linux Versions may seem like this:
Linux Kernel 2.6.39 ——— 0
Linux Kernel 2.6.39 Recovery Mode ——— 1
Linux Kernel 2.6.38 ——— 2
Linux Kernel 2.6.38 Recovery Mode ——— 3
Linux Kernel 2.6.37 ——— 4
Linux Kernel 2.6.37 Recovery Mode ——— 5
Step 2:
Now open the terminal and type the following command:
sudo gedit /etc/default/grub &The content of the this file looks something like this:
# If you change this file, run ‘update-grub’ afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
# info -f grub -n ‘Simple configuration’GRUB_DEFAULT=0
#GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash pcie_aspm=force”
GRUB_CMDLINE_LINUX=””# Uncomment to enable BadRAM filtering, modify to suit your needs
# This works with Linux (no patch required) and with any kernel that obtains
# the memory map information from GRUB (GNU Mach, kernel of FreeBSD …)
#GRUB_BADRAM=”0x01234567,0xfefefefe,0x89abcdef,0xefefefef”# Uncomment to disable graphical terminal (grub-pc only)
#GRUB_TERMINAL=console# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo’
#GRUB_GFXMODE=640×480# Uncomment if you don’t want GRUB to pass “root=UUID=xxx” parameter to Linux
#GRUB_DISABLE_LINUX_UUID=true# Uncomment to disable generation of recovery mode menu entries
#GRUB_DISABLE_RECOVERY=”true”# Uncomment to get a beep at grub start
#GRUB_INIT_TUNE=”480 440 1″
Step 3:
In the previous file notice the line: GRUB_DEFAULT=0
This line can be interpreted as “the default kernel/os is at order number 0” which in this case is Kernel 3.0. All we need to do is to change the line from GRUB_DEFAULT=0 to GRUB_DEFAULT=new_order_number.
For example if we want to make Windows as our default OS, the line will be GRUB_DEFAULT=6. If you want to change the default timeout (wait time before it boots into an OS) of 10 sec you can do that by editing the line GRUB_TIMEOUT=10 to GRUB_TIMEOUT=your_time.
Note:
Remember the previous Linux versions? Talking about the example given in Step 1, if we want Linux Kernel 2.6.37 to be our default we need to change GRUB_DEFAULT=0 to GRUB_DEFAULT=2>4.
Here the previous Linux version is at position 2 and Linux Kernel 2.6.37 is at position 4 inside it.
Step 4:
After changing the grub file, save and close it. Now run the following command:
sudo update-grubAfterwards, reboot the computer. Enjoy

How to get Google Music Beta Invite from outside US
I was craving to try for Google Music Beta since it’s launch but as it is only available for people of USA (why only USA?), all the time it irritated me with We’re sorry. Music Beta is currently only available in the United States. But then as you know “there is a will there is a way”, I managed to get an invite. All I did was to use the a US Proxy to request an invitation. I got my Google Music Beta invite in 3 days. Apparently once you get the invite, Google doesn’t bother from where your accessing it i.e. all you need to do is to use a US proxy and then once you get the invitation, it is yours to use it. To simplify the process in steps:
- Use a Google proxy site. I used http://www.ultrafastproxy.com/
- In this site, scroll down a bit to find a field with a Browse tag on it, enter music.google.com
- It will open Google Music page under the proxy
- If you have security features enable in the Google account, you might have to answer the security question to verify that this a legitimate login
- Now here you request for an invitation for an invite
- Wait for 3-4 day to process the invite request
- Once you get it you can access it from anywhere across the globe
You can also download the Google Music Manager, which is available for Windows, Mac and recently for Linux, to upload your own music to its cloud storage. You can upload upto 20,000 songs. But make sure that the music which your are uploading is legal. Uploading illegally downloaded music files will be deleted from the storage. One more thing once you get the invite, you can also send two invites to your friend.
Other Proxy Sites:
If the proxy site suggested earlier doesn’t work, you may want to try one of these:
