How to Disable or Enable Guest Session in Ubuntu 12.04

What is Guest Session:-The Ubuntu Guest Session feature provides a convenient way, with a high level of security, to lend your computer to someone else. A guest cannot view the home folders of other users, and by default any saved data or changed settings will be removed/reset at logout. It means that each session starts with a fresh environment, unaffected by what previous guests did.

Want to disable the guest account from showing up on the logon screen? Ubuntu 12.04 comes with a guest account that can be used by guests to access the system.

First open terminal (Ctrl+Alt+T)

and than type this command on the terminal sudo gedit /etc/lightdm/lightdm.conf

now give system password and press enter.

You will get Text editor in that you will see this lines

[SeatDefaults]

greeter-session=unity-greeter

user-session=ubuntu

now you add this line allow-guest=false

at the bottom of the file like this

[SeatDefaults]

greeter-session=unity-greeter

user-session=ubuntu

allow-guest=false

now save the file and restart

after restart you will see there is no Guest Session on the logon screen.

Want to Enable Guest Session:- go to Terminal and type this command sudo gedit /etc/lightdm/lightdm.conf

after opening Text editor you will see this lines

[SeatDefaults]

greeter-session=unity-greeter

user-session=ubuntu

allow-guest=false

just remove allow-guest=false line on that file and save that file.

Now restart the system, you will see Guest Session on the logon screen

Enjoy!

Speed up your Ubuntu 12.04 with preload application

what is preload application:- Preload is nice little application that could make your linux system a lot faster. Preload is an adaptive readahead daemon. It monitors applications that users run, and by analyzing this data, predicts what applications users might run, and fetches those binaries and their dependencies into memory for faster startup times.

Preload packages are available for almost all linux distributions. And it is available by default in the Synaptic Package Manager and Ubuntu Software Center in Ubuntu. Alternatively, you can install it via Terminal. Type this command

sudo apt-get install preload

Thats it. Preload will run silently in the background. If you want to further tweak Preload, conf file is available at /etc/preload.conf.

Note that installing preload will not make your system boot faster and that preload is a daemon that runs with root privileges.

And see the difference.

How do I clean Ubuntu?

Ubuntu software packaging system can accumulate unused packages or temporary files. These temporary files, also called caches, contain package files from all of the packages that you have ever installed. Eventually, this cache can grow quite large. Removing them allows you to reclaim space on your computer's hard drive for storing your documents, music, photographs, or other files.

To clear the cache you can use either the clean or the autoclean op for a command-line program caaled apt-get. The clean command will remove every single cached item, whicle the autoclean command only removes cached items that can no loger be downloaded (these items are often unnecessary).

To run clean go to Applications --> Accessories --> Terminal and Type

$ sudo apt-get clean

and it will ask password and give the password

packages can also become unused over tiem. If a package was installed to assist with running anogher program- and that program was subsequently removed-you no longer need the supporting package. You can remove it with autoremove

To run clean go to Applications --> Accessories --> Terminal and Type

$ sudo apt-get autoremove

it will remove the unnecessary packages.

How to Get Hardware Information On Ubuntu Using dmidecode

dmidecode is a tool for dumping a computer’s DMI (some say SMBIOS ) table contents in a human-readable format. This table contains a description of the system’s hardware components, as well as other useful pieces of information such as serial numbers and BIOS revision. Thanks to this table, you can retrieve this information without having to probe for the actual hardware. While this is a good point in terms of report speed and safeness, this also makes the presented information possibly unreliable.
The DMI table doesn’t only describe what the system is currently made of, it also can report the possible evolutions (such as the fastest supported CPU or the maximal amount of memory supported).
SMBIOS stands for System Management BIOS , while DMI stands for Desktop Management Interface. Both standards are tightly related and developed by the DMTF (Desktop Management Task Force).
