Installing Ubuntu7.10 on Acer4520

Filed under: Acer, Ubuntu — egoleo @ 7:35 am

System Specs
………….
Acer Aspire 4520
AMD64 Athlon X2
Nvidia GeForce 7000M
160 Gig
802.11b/g WLAN
1Gig DDR2

I have been trying for the past weeks since i had this laptop with
the above specs to run ubuntu7.10 but all failed. So i finally got myself
into runing 7.04 rather. But have finally gotten a way to run 7.10 on it and
this is how i did it.

I realised that anytime i installed the 7.10 and i reboot, it hangs at the splashcreen and so for some reason i felt it might be the menu.lst file so edited couple of times but nothing happened. so WHat i finally did was to get the 7.04 ubuntu cds and install and upgrade that to 7.10. And that worked. But when i upgraded the kernel to the original one used by 7.10, i got the same splashscreen hanging again. So i kept the upgrade on but now uses the 7.04 kernel rather instead of the 7.10 kernel which still works fine for me.

But after that, it wasnt all dont since it could not detect some of my hardware devices like the wireless and vga card.

1. to fix the X.
………………

I used the ubuntu livecd and mounted the installed my root(/) partition to get aaccess to xorg.conf file. commands below.

> mkdir /media/system
> mount /dev/sda1 /media/system

The above could be different for you. i mean the mount points

> cd /media/system
> vim etc/X11/xorg.conf

Once you are in this file, look for this lines

Section “Device”
Identifier “nVidia Corporation NVIDIA Default Card”
Driver “nvidia”
BusID “PCI:0:18:0”
EndSection

change the “Driver nvidia” part to “Driver vesa” instead and save and
reboot without the livecd.

2. how to fix sound too
………………………
simple first download the packages from the below site and copy them into one folder

http://www.alsa-project.org/main/index.php/Download

next

you need one of the c libraries and curses libraries for this i guess you are done with adding extra repositories if not message me i will explain

open the terminal and fire the following
sudo synaptic

and next search for g++ library

after that search for curses library for c

after this automatically done by the synaptic

go the folder where you have downloaded the packages and extract each and everything like below

> tar xjf alsa-(name of the package)

after extarcting just type this

> cd alsa-(extracted package)

next

> ./configure

next

> make

next

> sudo make install

do the above for all packages u just downloaded from the above link.
and afterward just reboot ur machine. u should hear sound now 🙂

3. howto fix wireless
………………….

Before we start, we have to make sure that MadWifi drivers don’t get loaded at boot, since we could have a conflict between the two. You can do this typing this:

blacklist ath_pci

in /etc/modprobe.d/blacklist file or by using the restricted driver manager:

> vim /etc/modprobe.d/blacklist

Install ndiswrapper
> sudo apt-get install ndiswrapper
> sudo apt-get install ndisgtk

you can also install ndisgtk or use synaptic instead of the console

after, download the Atheros driver
form this link http://www.atheros.cz/download.php?atheros=AR5006EG&system=1
anyway that is the link i used in getting mine to work.

afterwards you need to unzip the file just downloaded from the link

Install the .inf file in ndiswrapper, using ndisgtk or the command
> sudo ndiswrapper -i net5416.inf
from the unzipped file

Save ndiswrapper module configuration files by issuing the command:
> sudo ndiswrapper -ma && sudo ndiswrapper -mi

You can now reboot and bravo. u can check to see u should be done now.

Web users ‘getting more selfish’

Filed under: internet — egoleo @ 7:06 am

Web users are getting more ruthless and selfish when they go online, reveals research. This was made known by usability guru Jakob Nielsen in an annual report into web habits.
I think now people have fair idea as to what really they want or looking for on the web. Is not like sometimes back where people dont really know what exactly they want and so spend so much time on the web.
And in so doing, web users have become very impatient.

How to install perl modules through CPAN on ubuntu hardy server

Filed under: Perl, Ubuntu — Tags: , — egoleo @ 1:53 pm

This assumes that you have grabbed a copy of the ubuntu hardy server
cd from the ubuntu.com website.

1. Install all dependent packages for CPAN
sudo  apt-get install build-essential

2. invoke the cpan command as a normal user

$cpan

But once you hit on enter for “cpan” to execute, you
be asked of some few questions. To make it simple for
yourself, answer “no” for the first question so that
the latter ones will be done for you automatically.

3. Once the above is done, you will be present with the cpan
prompt. now enter the commands below

make install

install Bundle::CPAN

4. Now all is set and you can install any perl module you want. examples of what installed below

cpan prompt>  install  IO::File
cpan prompt>  install  Net::SMTP_auth
cpan prompt>  Email::MIME::Attachment::Stripper
cpan prompt>  Mail::POP3Client
