If you use the top command in Linux you are going to LOVE htop….

Htop is an ncursed-based process viewer similar to top, but it allows to scroll the list vertically and horizontally to see all processes and their full command lines.  Tasks related to proccesses (killing, renicing) can be done without entering their PIDs.

To Install Htop on Ubuntu Linux Just open terminal and type:

sudo apt-get install htop

In some cases uninstalling Pulse Audio Works, But you should try this first:

1. Open terminal

2. sudo gedit /etc/modprobe.d/alsa-base

3. Add to the end of the file:

options snd-hda-intel model=dell

4. Reboot and then go to the volume control and turned the speaker

volume up to maximum.

And You’re Done.

If it doesn’t work and you want to try to uninstall Pulse Audio Just open terminal and

sudo apt-get purge pulseaudio

You can also go and download The Original ubuntu 9.10 dell factory recovery iso

To do just that you need to create SSH Key Pair

1. we need to use ssh-agent to create an SSH key pair.

To do that run this command: ssh-keygen -t rsa

When prompted for a password, choose something long and secure.

After few seconds  you should see a message like:

Your identification has been saved in ~/.ssh/id_rsa.

Your public key has been saved in ~.ssh/id_rsa.pub.

Now we need to add the public key (id_rsa.pub) to our web server. You can head in to the web server via FTP and cut and paste the info into ~/.ssh/authorized_keys.

Or The terminal way, execute this line, substituting your login info:

cat ~/.ssh/id_rsa.pub | ssh YourUserName@YourServer.com ‘cat >> .ssh/authorized_keys’

Notes:

1. For some versions of ssh, you may have to use the ~/.ssh/authorized_keys2 file.

2. you can also use dsa instead of rsa.

*** For RSA keys the minimum size is 768 bits and the default is 2048 bits.

*** DSA keys must be exactly 1024 bits as specified by FIPS 186-2.

To make your files list in color just type ls -G, or make ‘ls’  show colors by default, this is how:
