Installing Ubuntu Server on Dell Dimension 2400?


Step 1:
The Ubuntu Linux operating system is available either with or without a desktop environment. The version with the desktop environment is meant for personal use and includes word processing, email and graphic editing software. The version without the desktop environment is called "Ubuntu Server." The server version does not come with any graphical software or productivity software. There are three different desktop environments available for the Ubuntu operating system. The default is the Gnome desktop. The other two are the KDE and the XFCE desktop environments.

Log into the server. Type the command "sudo apt-get update" to update the list of software packages available. Type the command "sudo apt-get install ubuntu-desktop" to install the Gnome desktop. Type the command "sudo apt-get install xubuntu-desktop" to install the XFCE desktop. Type the command "sudo apt-get install kubuntu-desktop" to install the KDE desktop. Type the command "sudo reboot" to reboot the server. Ubuntu Linux Tutorials,Howtos,Tips & News http://www.ubuntugeek.com/install-gui-in-ubuntu-server.html

Unlock CURRENT password on acer 250 netbook on ubuntu


Try these steps it worked for me it can work for you:

1. You’ll need to boot from your Ubuntu Live CD, choosing “Try Ubuntu without any change to your computer” from the boot menu.
2. Once the system boots, open up a new Terminal window from Applications \ Accessories and then type in the following command:

sudo fdisk -l (minus small leter L)

3. Now you’ll need to create a directory to mount the hard drive on. Since we’re actually booting off the live cd, the directory doesn’t really get created anywhere. then type

sudo mkdir /media/sda1

4.The next command will mount the hard drive in the /media/sda1 folder.

sudo mount /dev/sda1 /media/sda1

5. The command that actually does the trick is: chroot.
it is used to open up a shell with a different root directory than the current shell is using, and we’ll pass in the folder where we mounted the hard drive.

sudo chroot /media/sda1

6. Now you can be able to use the passwd command to change your user account’s password, and it will be applied to the hard drive since we are using chroot.

7. passwd 12345

Note: you’ll need to type your username after the passwd command in order to change the right password.

8. Now you should be able to reboot your system and log yourself in with your new password.

Root Password


Hi Daniel,
Ubuntu has the root account locked by default. If you need to run as root, you use sudo username (This is recommended)
If you want to have a root shell on an Ubuntu system (It is not suggestedsuggested)
sudo -i
This is equivalent to the "su -" command sudo -s
This is equivalent to the "su" command

Audacity sound ubuntu


Your command is slightly flawed. Try again as follows, making sure to include all spaces (copy and paste the command if it'll help)

sudo /etc/init.d/alsa-utils start

Note the space between sudo and /etc/blahblah and the space between /etc/blahblah and start. Also note the occlusion of the second L to the end of the alsa-utils command.

Hope this helps,
