How to fix your Boot up Screen resolution

Monday 7 July 2008 @ 1:45 am

I think it is not a problem for many people to find out every time you start your Ubuntu and find out the boot up splash screen is 640 x 480, instead of your preset resolution. But for perfectionist, it is very suffering.

Ok, here is a 3 steps method to solve this.

type “sudo gedit /etc/usplash.conf” in your terminal. After accessing with your root permission. You will see something like

# Usplash configuration file
# These parameters will only apply after running update-initramfs.
xres=640
yres=480

Just change the xres and yres to what your favourite resolution. Maybe 1024 x 768, then xres=1024, yres=768. After that, save it.

The last step, you need to type “sudo update-initramfs –u” to update your initramfs.

Reboot your PC and see whether you have a nice boot up GUI.

Ubuntu shell root: sudo

Saturday 10 May 2008 @ 11:01 pm

In Linux and Unix, users only allow to access files/folders with their permission only. However, under a superuser named root, users are able to have the privileges to all the administration work.

su root

su stands for Switch User. To access other users, just use their username instead of "root".

What Ubuntu different from other Linux distro is it includes sudo command. It will assign users for temporary root-level privileges. So, to execute your command in terminal under root-level privileges is simple, just add "sudo" before your command. Please note that the password require is user password and not the root password.

userA@machineA:~$ sudo vi /etc/testing.conf

"sudo -s" is equivalent to "su"

You do not have to worry when running GUI programs that require for root privileges as it will prompt for a password automatically.

Why there is only 4 primary partitions on a hard drive?

Sunday 2 March 2008 @ 9:17 pm

Nowadays, the hard disks sold on the market are usually more than 100GBs. Even though you have larger hard disk, but have you wonder why the maximum you could only have 4 primary partitions?

The reason is because in the first 512 bytes is reserved for the Master Boot Record (MBR). It stores the information of the partitions, but 512 bytes is only allows 4 primary partitions. So, if you have more partitions to create, then you need to create extended partition. And within the extended partition, you can have any number of logical partitions.
