Problem:After a successful upgrade to Ubuntu 11.10 from Ubuntu 11.04 I found myself struggling with login problem. Each time I tried to login with my root user it brought me back to login screen and the only way I could access it through guest user (pity!). [Read more…]
Sometimes you may need to provide the URL/link of a Facebook post or status for eg. in case you are trying to win a contest or trying to attract more people to a Facebook post. Though Facebook has recently added a “Share” option for all the Facebook post but it still doesn’t serve the purpose in the case you need the to share the Post in a comment or outside Facebook environment. In this post I’ll show you how to get the URL of a Facebook post.
All you have to do is to go to post and click on the “Date-Time” of the post. Something like this:
Clicking on this “Date-Time” element will take you to the post in a new tab. And from there you can simply copy past the URL of the post. Something like this:
Now you can share the post anywhere with the help of the URL. By the way the same method can be used in Google Plus as well.

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.
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:
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:
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.
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:

My AC power 
adapter charger for Dell Inspiron N4010 went into smokes two days back and I went to shop for a good (read cheap) alternate of it. After fiddling around a bit I settled for a “itworks” Universal Power Adapter (for 60 Euro sigh!). It comes with 12 plugs to use it with all the major laptop manufacturers and two type of power cords one for each North America and Europe. The below photograph is a not of my universal power adapter 😛
I went back and happily plugged the adapter into my laptop and switched it on. To my dismay, at boot time, it gave a warning message something like “AC Power Adapter type not recognized”. When I chose to ignore the warning and booted into the operating system, I saw the strange things with the battery icon. Despite of the adapter plugged in it was showing only 5% of battery left.
It took me some minutes to recognize my mistake, a blooper actually. This happens when you think you are too smart to ignore small details and turns out to be a fool.
As I said the Universal Power Adapter had a number of plugs for different manufacturers and it was numbered accordingly. In most foolish way I was using a plug meant for HP which somehow got fit into the socket. When I saw that and change it to the correct one the problem was solved.
Are you using the correct plug? Check it.
Recently when Ubuntu Update Manager ran on my Ubuntu 11.04 for the latest update it generated following error:
E: /var/cache/apt/archives/ubufox_0.9.1-0ubuntu0.10.04.1~mfn3_all.deb: trying to overwrite ‘/etc/xul-ext/ubufox.js’, which is also in package xul-ext-ubufox 0
Probing a little further I found out that it is a problem in upgrading to Firefox 5.0 and this ubufox is a modified version of Firefox for Ubuntu.
Follow these steps:
sudo apt-get install firefox
Hope it solves your problem. Question, suggestions and feedback are most welcomed. Enjoy
One of the many common problems one faces after installing Ubuntu is sound problem. In this case sound seems to be working, you can hear it on headphones but there is no sound coming out of speakers. Trying using alsa-mixer gives the following error:
load hw:0 error: Invalid argument
The solution provided here works for HDA Intel Soundcard. To find the make of your laptop soundcard click here.
Try the following command in the terminal:
killall pulseaudioYou need to edit this file /etc/modprobe.d/alsa-base.conf and then add a line in its end. Use the following commands:
sudo gedit /etc/modprobe.d/alsa-base.conf &Now add the following line at its end:
options snd-hda-intel model=genericNow reboot your computer. It should solve your problem. If the solution doesn’t work then try the Further Troubleshoot.
The term model = generic may not work in all the cases as sometimes it depends on the model of your sound card. Find your sound card here.
You can try replacing the word generic by the following words depending upon your laptop:
Acer aspire 2012
option snd-hda-intel model=basic
Acer
options snd-hda-intel model=ACER
Asus F3J
options snd-hda-intel model=uniwill-m31
Dell 6400 laptop
options snd-hda-intel model=dell
Dell Inspiron
options snd-hda-intel model=ref
Dell Dimension 9150
options snd-hda-intel model=ref
Fujitsu Siemens Amilo XI 1526
options snd-hda-intel model=fujitsu
Gateway laptops with a sigmatel audio device
options snd-hda-intel probe_mask=1
or
options snd-hda-intel model=test enable-msi=1 probe-mask=1
Lenovo:
options snd-hda-intel model=laptop-eapd
LG P1 Express Dual (ALC880 chip)
options snd-hda-intel model=lg
LG P1 with CMI9880 chip
options snd-hda-intel model=minimal
Toshiba Satellite a135-s2386
options snd-hda-intel probe_mask=8 model=3stack
Toshiba Tecra A8-103
options snd-hda-intel probe_mask=8 model=fujitsu
or
options snd-hda-intel probe_mask=8 model=fujitsu
If you could still not found the model you may want to look for the correct value to be used in model in the following file /usr/share/doc/alsa-base/driver/ALSA-Configuration.txt.gz. Unzip the file and look for your sound card. You may find values like this:
ALC260
hp HP machines
fujitsu Fujitsu S7020
Use the following command:
sudo gunzip /usr/share/doc/alsa-base/driver/ALSA-Configuration.txt.gz; sudo gedit ALSA-Configuration.txt &

I was installing Ubuntu 10.10 on my old laptop lately in dual boot mode with Windows Vista. I simply could not boot into Windows though I could easily boot into Ubuntu. After going through a number of Ubuntu forum threads, I figured out that it might be a problem with Grub and thus I decided to reinstall Grub. But update-grub did not detect Windows and displayed a message like this:
ls: cannot access any_path/boot Boot: No such file or directory
The reason which I found (on SourceForge) is that Grub2 was installed with Windows system partition chosen as the root-directory. This causes the folder /boot/grub to be created on the Windows system partition. Since ntfs partitions are case insensitive this leads to confusions between “/boot” and the already existing folder “/Boot”
Boot into your Linux OS and deleted or rename the folder /boot on the Windows system partition. Make sure that your don’t delete the /Boot folder. The /Boot folder contains the file “bcd” which is necessary to boot Windows Vista/7.
This solution worked for me flawlessly. Hope it works for you as well. Feedback, suggestions and questions are welcome. Enjoy

It has happened more than once with me. When I installed an application (freeradius, in this case) from its source code, it gives the following error:
radiusd: error while loading shared libraries:
libfreeradius-radius-2.1.10.so:
cannot open shared object file: No such file or directory
The reason for this error is that the libraries have been installed in a place where dynamic linker cannot find it.
Whenever I faced such problem, I used the following command. It has never failed me, not till now 😛
sudo /sbin/ldconfig -vHope this command solves your problem as well. Do provide me with your feedback, suggestions and questions. Don’t forget to like/vote the post. Enjoy
Sometimes it happens that running the updates in Ubuntu results in following error:
Could not initialize the package information.
An unresolvable problem occurred while initializing the package information.
Please report this bug against the ‘update-manager’ package and include the following error message:
‘E:Encountered a section with no Package: header, E: Problem with MergeList /var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_natty_main_binary-amd64_Packages, E:The package lists or status file could not be parsed or opened.’
While running sudo apt-get update results in the following error:
Reading package lists… Error!
E: Encountered a section with no Package: header
E: Problem with MergeList /var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_natty_main_binary-amd64_Packages
E: The package lists or status file could not be parsed or opened.
Moreover, Synaptic Manger fails to start as well.
The trick which worked with me is running following commands in the terminal (open terminal using Ctrl+Alt+T):
sudo rm -rf /var/lib/apt/lists/* sudo apt-get update
Hope it solved your problem. Please do subscribe the blog to stay in touch. Suggestions, questions and feedback are welcome. Enjoy
