Install Gammu

Installing gammu is surprisingly easy (once again thanks to the wonders of apt-get), just use the following command:

sudo apt-get install gammu

Hard wasn’t it? 😉

OK now it’s time to plug your phone in and see if we can get things talking. With the phone connected, type the following command:


you should now see your phone listed as a device – for example:

Bus 001 Device 002: ID 0421:0802 Nokia Mobile Phones

if not – make sure your cables and power are all good and try again.

The gammu installation comes with some example configuration files which are worth using as a starting point – if nothing else they help you to understand how gammu can be configured so that you can tailor a solution for your needs. These are located in
/usr/share/doc/gammu/examples (in gZip archives).

Copy the gammurc file to /etc/gammurc :

sudo cp /usr/share/doc/gammu/examples/config/gammurc /etc/gammurc

Now edit /etc/gammurc to specify your port and connection type (this will vary based upon where/how you have things plugged in and what sort of cable/interface your phone is using). The settings for mine are:

port = /dev/ttyACM0
connection = dku5

Save this config and from the shell type:

gammu –identify

you should now be presented with some information regaqrding your phone such as:

Manufacturer : Nokia
Model : 7200 (RH-23)
Firmware : 3.110 T (18-03-04)
Hardware : 0903
IMEI : 353363000813894
Original IMEI : 353363/00/081389/4
Manufactured : 04/2004
Product code : 0514143
UEM : 16

If this is the case then you have got gammu up and running and can send yourself a test message with the following command:

echo “boo” | gammu –sendsms TEXT [recipient mobile number]

It is very easy and simple to install Compiz & Compiz Fusion plugins on Lucid Lynx.

Just Click Application —> then Ubuntu Software Center

Ubuntu Software Center pop up

Search for CCSM

Click install and then give the root password to install CCSM

Installation Progress

After the CCSM installation completed, install Nvidia drivers

Click System –> Administration –> Hardware Drivers

Then the system searched for available drivers and i choosed the recommended Nvidia accelerated graphics driver (version 173) option from the list and then activated the driver by clicking Activate button.

Restart the system, so that the new nVidia graphic display driver will be ready for use.

Then enabled the desktop effects by clicking System –> Preferences –> Appearance and on the –> Visual Effects tab, selected Normal .

After this installation my desktop looks great, very much happy to use Desktop effects in Ubuntu 10.04.

After reading this you too will be enjoy using  Compiz & Compiz Fusion plugins in Ubuntu 10.04 (Lucid Lynx).

After I install Ubuntu 10.04 , I found the new default theme has the Minimise, Maximise and Close buttons have been moved from the top right, to the top left.

It is very difficult for me to use these buttons on the left.

Now, How do I move the Minimise, Maximise and Close buttons Back to the Right  ?
To move now Press Alt+F2 , enter “gconf-editor” in the text field, and click on Run.

The Configuration Editor should pop up.

Click on the + button next to the “apps” folder, then Click “metacity” in the list of folders and then click on the “general” folder.

Double-click button_layout to edit it on the right side .

Change the text in the Value text field to:


Click OK and the change will occur immediately.

Now you will see the Minimise, Maximise and Close buttons have been moved to top right.

Now it is really good see the buttons back to top right, and after reading this you too feelto move the Minimise, Maximise and Close buttons back to the Right in Ubuntu 10.04 .

Hubs, switches, and routers are all devices that let you connect from one computers to other computers, networked devices, or to other networks.

Each has two or more connectors called ports into which you plug in the cables to make the connection.

Hub :
A hub is a small, simple, inexpensive device that joins multiple computers together. Its job is very simple: anything that comes in one port is sent out to the others. That’s it. This is quick and easy ways to connect computers in small networks.

Hubs operate using a broadcast model

Switch :

A switch is a small hardware device that joins multiple computers together within one local area network (LAN). a switch generally contains more intelligence and a slightly higher price than a hub. switches are capable of inspecting data packets as they are received, determining the source and destination device of each packet, and forwarding them appropriately. For example, if it sees traffic from machine A coming in on port 2, it now knows that machine A is connected to that port and that traffic to machine A needs to only be sent to that port and not any of the others.

switches operate using a virtual circuit model.Switching involves moving packets between devices on the same network.Switches operate at layer 2 of the OSI Model.

A switch is able to determine where a packet should be sent by examining the MAC address within the data link header of the packet (the MAC address is the hardware address of a network adapter). A switch maintains a database of MAC addresses and what port they are connected to.

Router :
A router is a small hardware device that joins multiple networks together. These networks can include wired or wireless home networks, and the Internet.A simple way to think of a router is as a computer that can be programmed to understand, possibly manipulate, and route the data its being asked to handle.

Routing involves moving packets between different networks. Routers, on the other hand, operate at layer 3 of the OSI Model.

A router is able to determine where to send a packet using the Network ID within the Network layer header. It then uses the routing table to determine the route to the destination host.

GNU is a computer operating system composed entirely of free software. Its name is a recursive acronym for GNU’s Not Unix.

It was chosen because its design is Unix-like, but differs from Unix by being free software and by not containing any Unix code.

The logo for GNU is a gnu head

GNU Head logo originally created by Etienne Suvasa.

GNU is developed by the GNU Project and the development of GNU was initiated by Richard Stallman and then publicly announced as GNU operating system on September 27, 1983, which was the original focus of the Free Software Foundation (FSF).

Richard Stallman
wanted computer users to be “free”, as most were in the 1960s and 1970s — free to study the source code of the software they use, free to share the software with other people, free to modify the behavior of the software, and free to publish their modified versions of the software.

The goal was to bring a free software operating system into existence.
