Numeric Keypad Can't Be Used in Ubuntu 10.04

At the time of typing xls files that are opened and in-editing using OpenOffice which runs on ubuntu, sometimes we need the number keys (numeric), which are grouped to the right of the keyboard.

It would be sad if the number keys can not be used. At the time I thought for key numerical keyboard is damaged, because at the same time the numeric keys also can't be used for typing in the empty text file.
The keyboard I try in Windows, it's OK ....(Well I think this keyboard would not be damaged).

With Smart Mobile Phone Haier C700 I googling and finding an article titled Fixing the borked numeric keypad in Ubuntu Hardy.

Thanks God, my question has been answered. Here's the steps :

• Access Menu System -> Preferences -> Keyboard
• Go to the Mouse Keys tab
• Remove the check (uncheck) on the option Allow to control the pointer using the keyboard

This also can be applied to all who use the GNOME 2.22

Thus that can be shared by John Salim hopefully useful

Modify Boot Loader (GRUB) in Ubuntu 10.04

If in our computer have more than one OS (Operating System), for example the Ubuntu and Windows, and we install Windows first and then Ubuntu, then we have the Boot Loader (GRUB) provided by Ubuntu.

How do I modify the Boot Loader (GRUB) on this Ubuntu?

Here's a little that I can share:

• Open a terminal and type sudo gedit /etc/default/grub
  Will open the grub file. We can change its time-out and default (Default OS run, Windows or Ubuntu). If we only have 2 Operating Systems, Windows and Ubuntu 10.04 for example, then change the default from 0 to 4, then if we turn on the computer and do not select, so Windows will be run.
• Do not forget to press the Save and Close
• Then type sudo update-grub
• The next command sudo gedit /boot/grub/grub.cfg
  Grub.cfg file will appear. Here can be replaced string that is displayed in the GRUB. Suppose we want to replace the words "Windows XP" to "Door XP" or "Neighbor Door" hehehe .... :D
  
• Click the Save button (Ctrl-S), Close and Restart Computer, or can also be typed sudo reboot

Thus that can be shared by John Salim, hopefully useful...

Cloning Harddisk with Ubuntu 10.04

Some time ago I want to clone harddrive containing Repo Server Ubuntu 10.04. Initially tried googling and looking cloning software. HDClone and diskcopy found, but I found a Total Failure. And I've waited a long process of cloning using HDClone. After waiting 5 hours ......oh no.... it did not work .... even though the process of cloning reassure you know, there was no warning of any errors.

A few days later I tried using Norton Ghost, also failed. There is a warning that the drive does not unmount perfectly. I tried unmount in ubuntu but still the same. I thought this dear Norton Ghost reasons that are not able to clone Repo Server Ubuntu 10.04.

After trying many different ways with different kinds of software such as Norton Ghost, HDClone, DiskCopy, which all failed, I was googling again and found a posting on www.linux.com titled Clone your Ubuntu installation onto a new hard disk that is written by Keir Thomas, I tried ......and..........YES SUCCEEDED...thank you to Mr. Keir Thomas.

This cloning using ddrescue software running on ubuntu. Here are the steps :

• At first I remove all partitions on my harddisk destination
• Install ddrescue first by typing the command sudo apt-get install gddrescue
• Then check your hard disk by typing the command in a terminal sudo fdisk -l
• Results from the above command will perform 2 harddisks is /dev/sda (the first harddisk to be the source) and /dev/sdb (second harddisk to be the destination in this case a second harddisk is still empty)
• Starting the cloning process by typing the command sudo ddrescue -v /dev/sda /dev/sdb
• Visible progress in cloning .... wait for it to finish ... took an hour or more depending on the contents of the cloned harddisk and also the processor used
• When you're finished ... shutdown the computer, remove the source harddisk and boot from cloned harddisk to ensure that the cloning process was succesful

So that can be shared by John Salim, hopefully helpful....
