Lenovo 3000 N200 sound card problem solved

My Laptop is a lenovo 3000 N200.After i installed Ubuntu 8.04 my sound car was not detected by the system.
And also there were no software to test my finger print reader.

To fix the sound card problem in Lenovo 3000 N200 what i did was

1. open alsa-base file in the /etc/modprobe.d directory using a text editor

eg: $sudo vim /etc/modprobe.d/alsa-base

2 .then add following line to the end of that file

options snd-hda-intel model=lenovo
(and saved the file)

3.Open a empty text space and add the same line to that and save it as modprobe.conf in /etc/ directory and /etc/modutils/ directory

then i saved the files and restart the machine

finally i heard the sweeeeeeet Ubuntu starting sound........Cooooool
My next step is to find a fingerprint reader software for my fp reader....

Dialog HSPA modem in Linux /Ubantu


Finally i managed to use my Dialog HSPA modem in Ubantu 8.04 .It is a Huawi e220 modem i used to connect.I didn't successful in using wvdial in this case.
So what i did is update the ubanu network manager by adding some src url to my update list file
this is the steps i followed

1. go to /etc/apt

2. open source.list file in a text editor (you must set the R/W active to the file before that)

3 Add following two lines to the end of the file

deb http://ppa.launchpad.net/network-manager/ubuntu hardy main
deb-src http://ppa.launchpad.net/network-manager/ubuntu hardy main

and save the file

4. type apt-get update in the terminal (Better do it as the root)

5.Then update manager will appier in the task bar( its a arrow directing down direction to indicate download)

6.DO the update and restart the machine with modem connected.

7.go to system->preferences -> network configuration to configure the connection




if you do not have a internet connection ,
use following url to download network manager
http://packages.ubuntu.com/gutsy/i386/network-manager-pptp/download

But what I did was i net worked my machine with windows machine and use my dialog modem to connect to the internet using that machine and share the net connection so that i can update Ubuntu online

have fun.......
