As you know, xorg.conf is a X window system server configuration file. This configuration file is searched for in /etc/X11 folder when X server is stared. It allows you to configure your screens and graphics divers.

With previous versions of the Ubuntu Linux, you have to modify this file manually. This is a problem for beginners who don't understand how to edit the content of the file in correct syntaxes. For an IT person, he also worries about that because if he makes any mistakes, the X server can be broken. So, that should be nice if he make a copy of this file before changing some parameters there. Like this
sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf_backup

Now, you can do it in Ubuntu 7.10 (Gutsy Gibbon) with the support of a graphical user interface. This tool makes the configuration of X Window easier.

To open this tool, you select System > Administration > Screens and Graphics

Then, you can select your graphics card and a right resolution of your screen. The configuration file xorg.conf will be updated automatically after you click "OK" button on this tool. Ubuntu Linux is better and better.

If your computer system is booting slowly or your splash screen is not shown it could be that usplash has created a splash screen incorrectly. This tip will show you how to remove incorrect resolution in Grub configuration file to improve your booting performance.

  • Step 1: Identify what the resolution and color on your machine in the following table

# +--------------------------------------------+
# | 640x480 800x600 1024x768 1280x1024
# ------+--------------------------------------------+
# 256 | 769 771 773 775 |
# 32K | 784 787 790 793 |
# 64K | 785 788 791 794 |
# 16M | 786 789 792 795 |
# +--------------------------------------------------+
For example: if you know the color is 64K and the resolution is 1024x768, you will get a value of 791 for VGA.

  • Step 2: Edit /boot/grub/menu.lst file
sudo gedit /boot/grub/menu.lst
  • Step 3: Search "splash" and move to that line, like this
kernel /boot/vmlinuz-2.6.22-14-generic root=UUID=bc93b5ac-7bfa-4dc6-a121-efffdae0057a ro vga=792 splash
  • Step 4: Replace the wrong value (e.g. 792) with a correct one (e.g. 791) and save the file
  • Step 5: Edit /etc/usplash.conf file
  • Step 6: Change to your resolution and save the file. e.g. in this case
# Usplash configuration file
  • Step 7: Get you kernel version
uname -r
The result looks like this

  • Step 8: Rebuild the bootsplash screen, e.g. like this
sudo update-initramfs -u -k 2.6.22-14-generic
  • Step 9: Reboot your computer

Basically the network interfaces have been configured already during installation of Ubuntu Linux. However, if you are a new Ubuntu user, you should know a little bit about how to add or remove network devices on your Ubuntu box. This post is also useful for anyone who has a troubleshooting with network connection.

Open a Network-Admin Tool

System > Administration > Network
You will go to a "Network Setting" panel as the following screen. At the default mode, the first tab (Connections) is selected. This tab allows you to setup all network connections.

In this case, I have two different network cards. Both of wired and wireless network interfaces are currently configured for using DHCP address. Dynamic Host Configuration Protocol (DHCP) is a protocol used by networked client computers to obtain IP addresses and other parameters from a DHCP server.

Now, I try to click on the second option "Wired Connection" and hit "Properties" button. Here, I can see that the check box has been sticked to mean that "This connection has been configured" for interface eth0. From the drop-down list of configuration field in "Connection Setting" part I can identify what kind of IP address should be used for this connection (a static IP or a dynamic IP).

For the first option in "Network Setting" Panel is checked when we want to use a wireless connection. You have to make sure that your computer support for a wireless card to configure for this connection. The following screen shows that you have configured for your wireless network device as the interface eth1. This interface will be connected to a network named WLAN-555 with two parameters about password for network authorization.

We continue with the second tab (General) in the "Network Setting". This part allows you to put a name and domain for your host as shown in the following picture.

The third tab can be used to identify a Domain Name System (DNS) which translates hostnames to IP addresses. This is needed for network devices in delivering information. Just click "Add" button and enter a new IP address of your DNS server and click "Delete" to remove an existing address from the available list.

The remanding tab let you create aliases for local IP address on your computer. Look at some examples in the following pictures.

Hopefully, it is useful for you. Thank you for your reading.

sources.list is a package resource list used to locate archives of package distribution system. In Ubuntu, this control file is located in /etc/apt/sources.list to support APT for searching, updating, and installing packages. Each line is one separate source written in a given syntax.
You can customize this file by adding or removing any source you want. However, what is the problem if you are not sure how to modify it or currently your sources.list doesn't work well. You don't need to worry about that because you can use Ubuntu sources.list generator. With this generator you can create your own custom sources.list from various available sources. It takes only two simple steps. First, you select your country, Ubuntu version, and the architecture of your computer. Second, you take any repositories you like and click "Create sources.list" button to generate the content of your sources.list file. And I think that you know what to do then.
