How to configure Your Cell phone in Linux OS for Internet connection

I tried this steps in Ubuntu OS from My Sony Ericsson K510i. I am using Airtel Subscriber.
Hope it will work in other Linux distros also.

Step 1:
Start your pc and now enter id root and password (you must be knowing that!) Now open terminal and type "dmesg" It will detect all the device connected with your pc including your (usb, serial ) data cable.and it will display log in the same terminal read that log carefully now check which port has been detected by it. It detected ttyUSB1 on my pc.

$wvdialconf /etc/wvdial.conf
it will detect ur mobile and it will write the value on wvdial.conf file in etc directory.

Now open the file /etc/wvdial.conf from your terminal,
$vi /etc/wvdial.conf
In that file, you can show a existing configuration. You just remove all the lines and paste the following code.

#Paste the following lines to your wvdial.conf file
[Dialer Defaults]
Modem = /dev/ttyUSB1 #note1
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
stupid mode = 1
Modem Type = Analog Modem
Phone = *99# #Note2
ISDN = 0
Username = a
Password = b
Baud = 115200

#Note1: May be varied depends upon your hardware config.
#Note2: First check your mobile phone dial No.

step 3 Open the file, /etc/resolv.conf and enter following lines. Now dont delete the existing lines. You just append.

service named start

Now log out and log in as User and open terminal now type su - and press enter, than type root password for your super user mode.
Then type wvdial R in your terminal
Hope now you are connected to Internet now enjoy surfing . If u want to disconnect than just press CTRL + C or killall pppd
And it will disconnect active connection!.

Sound card problem in Acer Aspire 4520

Recently I bought a Acer Aspire 4520 laptop. I installed some Linux OS includes Fedora 7, Open SUSE 10.3, Ubuntu Fiesty and debian. But None of my installed OS detected my sound card. Finally I removed all the distros and installed Ubuntu Gutsy 7.10 and then downloaded latest ALSA-Driver from Installed this driver. Now My sound card is working fine. Here I have noted the steps what I have done for my sound card problem. It will useful for someone to search solution for this problem. And here I have given the link for ubuntu forums. Seems, more people getting this problem. Ref this page, before you start to install the alsa,

Steps for installing the ALSA Driver:
* Installed Ubuntu Gutsy version for 64 bit
* login in console mode
* By default, the nvidia driver installed. Install the driver by using
$apt-get install nivida-glx-new
$sudo nvidia-glx-config enable
Then retsart the Laptop. Now almost the video problem will solved.

* Updated the packages.[kernel also updated]
* Installed build-essential from package manager. It has resolved lot of dep problems.
* Downloaded alsa-driver-1.0.15rc3.tar.bz2
* Untar it
* $./configure
* $make
* $make install
* sudo vim /etc/modprobe.d/alsa-base
added this "options snd-hda-intel model=acer" in almost last line. Aft that save it.
* Reboot
* Now my lapy logged in with nice Ubuntu sound. The sound card working fine.
Thanks to ALSA and Ubuntu....
This is the common steps for all the distros.
Have the Fun..
