Changing the screen resolution ubuntu 12.04
If your monitor is not detecting the desired in the gui mode
You need to create xorg.conf file under /etc/X11 directory
Add the display modes to /etc/X11/xorg.conf
If you don’t have a xorg.conf, then you can use the following as a basis. You need to replace the entries with the names Modeline, Driver and Modes with the correct entries for your system. Depending on your hardware, you may need additional entries, for example if your system has more than one graphic chip.
Modeline “1280x1024_60.00” 109.00 1280 1368 1496 1712 1024 1027 1034 1063 -hsync +vsync
Modeline “1024x768_60.00” 63.50 1024 1072 1176 1328 768 771 775 798 -hsync +vsync
Modes “1280x1024_60.00” “1024x768_60.00”
If you don’t know the name of the video driver that your system is using then you may get the name as follows (if you have an intel graphic chip, the driver name is just “intel”):
lshw -class display | grep “driver”
The modelines can be generated with cvt:
Changing Passwords in ubuntu 12.04
If you want to change the password for any user account you can just give
kiran@localhost:#sudo passwd “username”
If you are getting Authentication Manipulation error then you do not have privileges to change. You must do it at as a root user
By default Ubuntu wont create a root passord, you can set the root password
sudo password root
Switch to root user
If the root password is aleady changed or you forgot your root password then reboot your machine and enter into recovery mode , Or use a Ubuntu live cd
1. When you get the grub menu appears, select option with recover as shown in figures.
Boot into the recovery mode , and then select drop into root shell prompt
Mount the filesystem into read write mode
root@localhost$:mount -o rw,remount /
root@localhost$:sudo passwd root
Different desktop environments
If you are not comfortable with the default unity desktop environment , You can try other desktop environments
And also if you system is old and doesn’t support high end graphics then you can try light weight desktop environments (XFCE and LXDE) as they wont use up too much ram
sudo apt-get install xubuntu-desktop
sudo apt-get install lxde
Last but not the least If you are not a keyboard person and heavily dependent on Mouse you can use Gnome 3
sudo add-apt-repository ppa:gnome3-team/gnome3
sudo apt-get install gnome-shell
Keep of the Grass By Karan Bajaj
After reading Jhonny Gone down his second Novel which impressed me very much
Jhonny gone Down is a must read for anybody, the plot is too good and it will keep on hook.
I decided to read karan Bajaj debut novel, keep of the grass
The book has one main character is IIMB Bangalore and MBA career.
All Mba aspirants and those who are doing mba presently will absolutely connect with this book
The book seemed like a college diary of what 2 years of MBA will look like
Though the main character tries the path of spirituality, self discovery and corporate mumbo jumbo it doesn’t impress you much
At some point you may wonder as it follows the same plot as five point someone.
I would rate karan bajaj is a much better writer than Chetan Bhagat
Definitely one of writers to watch out for in future
Revolution 2020 Chetan Bhagat Novel Review
After reading Chetan Bhagat new offering i can definitely say that he has lost his mididas touch
He should join bollywood as a script writer rather than continuing his career as a writer
The story offers nothing new as we have see countless number of Bollywood featuring triangular love stories.
There is a remarkable outrage when Chetan Bhagat whenever he tweets some of the comments are hilarous.
Chetan bhagat is no stranger to controversy like 3 idiots credit issue, Lok pal bill issue.
His articles on Times of india are such crap uses cheap publicity stunts to promote his books.
For die hard Chetan Bhagat fans it may be a treat his blog

Ubuntu 11.10 and Gnome Interface
It has been a few days since i started using the ubuntu 11.10
It has some good features specifically rich in desktop features, if you want the new rich features it won’t work work on older laptops the installation falls back back to default mode
Since 11.04 Ubuntu has moved on from Gnome to Unity and change has not impressed me much
It takes some time to get used to the new interface as our minds are wired by default to find the taskbar on downside of the screen as Unity sidebar is shifted to the right side of the screen You need to be a master of keyboard shortcuts to be good
Here is a link for keyboard Short cuts
Install the compiz application so u can play around with the desktop
Install your favorite apps, through the ubuntu software centre is completely modified, the new look is good it is easy to find the required applications it is on par with itunes, android market
Ubuntu is definitely gearing up to enter the mobile and tablet market considering the new changes
The synaptic manager is completely removed which is a good thing i suppose considering the number of steps one has to generally go through before installing any application
Here is a comprehensive review of ubuntu 11.10
Some tweaks which are very useful
If u are comfortable finding the sidebar down this tweak will help
I would recommend to install the gnome shell
Installing different Themes
Weekend Gateaway(Mudumalai and Goplaswamy Betta)
Ok Here goes my first official tumblr post
The trip was entirely unplanned me and my group of four friends decided to go instead of lazing around in homes.
We began searching for various places for a 2 day trip. The options were
1.Gokarna beach and Mangalore side as beaches were abundant over there
2.Coorg side for a cool road side trip.
3.Mudumalai Tiger Sanctuary.
Mangalore and coorg side got cancelled as there huge rains over there thanks to some inside information.
So it was decided to go Mudumalai and surronding areas.
Booked a Tavera and we were set to go.
It took around 5 hr to reach the Bandipur the road through the forest was closed from night 10:30 to morning 6 had to wait for 45 min to get the green signal :-)
Decided to head directly head to Mudumalai tiger reserve first. Crossed over to Tamilnadu.
Greeted by wild elephants on the way
Reached Masinagudi small town which is just 30km from Ooty which had the Niligris Mountain range in full glory.
The Resorts were numerous in this small town we checked into Mountain view resort as the rates were economical.
Decided to explore the hills and forest area it was kind of a adventurous when we went deep inside the forest with no guide
The water was crystal clear an streams were abundant
We spotted lot of Deers,Peacocks,Boars,langurs but were unable to spot a single tiger,lepoard even the night safari didn’t help us which cost us a fortune and everybody were pissed of at the driver :-). when he showed same set of deers again and again.
Reached a temple of deity Murgan which was constructed at the top of the mountain had breathtaking views of the mountain range. The temple pujary gave us an intresting trivia that the temple was maintained by bollywood actor Mithun Chakravarthy
Decided to head Back Home On the way we stopped at Gopalswamy Betta,which had the best views of the mountain range and also temple dedicated to lord Krishna.
Had a great time:-)

How to installl cracked apps for iphone
I was waiting a long time for the release of ios 4.2.1 which fixed my iphone 3g slow and performance issues. I was stuck at ios 3.1.3 for about three months and the most of the new apps that released during this time required ios 4.x and later versions.
The jailbreak community was delaying the unlock\jailbreak as apple was expected to release ios 4.2.1 in November 2010 they didn’t want to take a chance to risk their jailbreak being patched by apple
Well it was worth the wait as the release pretty much fixed all the issues for iphone 3g. There are many jailbreaks available for but it is better to use redsnow and ultrasnow versions to jailbreak as you will not run into problemns during the installations. The website www.redmondpie.com contains all the guides to go about jailbreaking the iphone, while jailbreaking please deselect multitasking and homescreen wallpaper options as it will lead to more slowness in iphone 3g
Now most of the apps are in the paid sections The cost may vary upon the app popularity usually (.99$ to 4 $). The free paid apps are good but for the complete features you have to pay
First step is to install installous
- Open Cydia, add this source: http://cydia.hackulo.us
- Install “Installous ver 2.0″ and

There is a problemn on ios 4.2.1 and openssh need to reinstalled everytime you want to copy some file to ur phone
I will be trying to use ifile which many have said the easiest method to transfer files.
In the next post i will explain how to use ifile
One disadvantages on ios 4.2 is now it is not detecting on ubuntu 10.10 the lib mobile is not working properly if that was working you can directly copy the ipa file no need of a secure ssh connection
