Solving Heating Issues in Ubuntu 12.04 LTS

Hello Everyone !!

Thanks for Ubuntu Team because 12.04 LTS is a full featured OS and a major

competitor to all other OS . But its been a problem as i have experienced Heating

Problems while running ubuntu 11.10 so i changed to Linux Mint 12 which is

better in heating discharges.After the release of Ubuntu 12.04 it also has the

same Heating Discharges in Laptops about 80-90 C .

Then found the problem is due to Graphics card and also with Sandy Bridge

Processors so follow the below steps for solve that problem.

For Nvidia drivers (Bumblebee):

To install Bumblebee

Open the terminal and start type the command

   sudo add-apt-repository ppa:bumblebee/stable

If you run Ubuntu 11.04 or older then type this command

sudo add-apt-repository ppa:ubuntu-x-swat/x-updates

Then run the following

   sudo apt-get update

  sudo apt-get install bumblebee bumblebee-nvidia

Its done now check with Psensor before and after installation of bumblebee

For AMD drivers

open terminal and type

    sudo apt-get install fglrx-updates fglrx-amdcccle-updates

then, after finishing the job type

   sudo aticonfig –initial –input=/etc/X11/xorg.conf

Its done

   I personally thank the bumblee and amd teams for solving the bugs and

also Ubuntugroups and users for sharing the knowledge.

Python+MySQL connectivity

Hi friends

If you are new to ubuntu-linux or u are working with python,this is one  of the way for installing and

accesing MySQL database using Python language.

Step 1: Install python 2.6 normally it will be installed in ubuntu

sudo apt-get install python2.6

Step 2: Install the Lamp-server

sudo tasksel install lamp-server

and watch this video for how to configure Lamp-server

Note: Install and configure using “root”

Step 3:Install MySQL DB

sudo apt-get install  python-mysqldb

Step 4:   Test this through python by typing

root@thoufiek-linux:~# python
Python 2.6.5 (r265:79063, Apr 16 2010, 13:09:56)
[GCC 4.4.3] on linux2
Type “help”, “copyright”, “credits” or “license” for more information.
>>> import MySQLdb
>>> exit()

If u find error like this.

>>> import MySQLdb
Traceback (most recent call last):
File “<stdin>”, line 1, in ?
ImportError: No module named MySQLdb

Step 5:Create a Simple table

If you have installed mysql then you should be able to do the following steps and create a dummy table and insert data into it:

root@thoufiek-linux:~# mysql -u root -p
Enter password:
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 47
Server version: 5.1.41-3ubuntu12.8 (Ubuntu)

mysql>

Type ‘help;’ or ‘\h’ for help. Type ‘\c’ to clear the current input statement.

Create a Databse:

mysql> create database hello;
Query OK, 1 row affected (0.00 sec)

mysql> use hello
Database changed

mysql> create table employee(id int,name varchar(20),email varchar(20));
Query OK, 0 rows affected (0.05 sec)

mysql> show tables;
+—————-+
| Tables_in_data |
+—————-+
| employee       |
+—————-+
1 row in set (0.00 sec)

mysql> insert into employee(id,name,email) values (1,”Afridi”,”afridi.pak@yhaoo.com”);
Query OK, 1 row affected (0.00 sec)

mysql> select *from hello.employee;
+——+——–+———————-+
| id   | name   | email                |
+——+——–+———————-+
|    1 | Afridi | afridi.pak@yhaoo.com |
+——+——–+———————-+
1 row in set (0.00 sec)

mysql> exit
Bye

 

Welcome

Hi

I am thoufiek , pursing my B.E degree in the discipline of Computer Science and Engineering  in I.F.E.T college of engineering.I liked to work with linux and completely migrated to it..

I’m here to share some information and contributions to linux.

Now i’m trying myself with the Ubuntu-linux,which got a very nice user interface.Currently using Ubuntu 10.04(Lucid lynx) which is derived as a Debian based OS..

Being my first post..I’m sharing some information about Ubuntu-linux1

The following are the Ubuntu versions with their representing names..!

1. Ubuntu 4.10 (Warty Warthog)
2. Ubuntu 5.04 (Hoary Hedgehog)
3. Ubuntu 5.10 (Breezy Badger)
4. Ubuntu 6.06 LTS (Dapper Drake)

Another interesting fact about Ubuntu ,they will be updating their OS for every six months.

and also they will follow alphabetical order in their very versions for that you can refer the table.

I’ll start contributing my efforts to the developing of linux…
