Change Background Image in GRUB through command line

It is actually very simple to change the grub background image in LINUX and edit the grub and put it over there however there are a few ground rules we need to remember .

It should be a xpm image with just 14 colours in it ( that is sadist but thats the way it is)

It should be a 640 x 480

Gzip it

Now going step by step walk through how to change the background through your terminal

• Once you have gzipped your image copy it into your /boot/grub/
  • sudo cp -v source /boot/grub/splash.xpm.gz
• Login as root
  • sudo -i
• Use a text editor gedit or vi
  • gedit /boot/grub/menu.lst ( I prefer vim wirte now)
• Now you will find something known as #pretty colors
• Under that splashimage=(hdX,Y)/boot/grub/splash.xpm.gz where X is your hard disk no  and Y refers to the parition in my case it is(hd0,6)
• Save it and exit

You are done… Cheers

Running a startup script in UBUNTU 9.04

Last few days I was trying out some new script in which we had to log in and start the script.. Well while I messed up the whole thing as I had put the script before logging in and I could not use my computer furthermore( ofcourse, I removed the script but that is something different) so I decided to put how to put a script before logging in and after logging in Ubuntu

PUT A SCRIPT BEFORE LOGGING IN

1. Write your script in bash
2. Save it in a file named startup or anything you wish to..
3. Copy this file to the directory /etc/intit.d/ (you may use cp -v source destination or mv -v source destination)
4. Make your copied script executable by using chmod +x startup
5. then type the following commands update-rc.d startup defaults

INSERTING A SCRIPT AFTER LOGGING IN

1. Doing this is as easy as doing it in Windows
2. Go to System->Preferences->StartUp Applications
3. Click Add
4. Write your App’s name
5. Make sure your app is executable and provide a link to it in the command prompt
6. You can also a bash command in command dialog box
7. Enter a description if you want to
8. Click Ok and you are done…

Changing computer name in UBUNTU 9.04

Well with the new ION proxy authentication I was forced to change the my laptop’s name. I use windows 7 and UBUNTU 9.04 which the ION people obviously could not change. So I decided to change its name myself for the first time.

1. Open Terminal and then type
2. gksudo gedit /etc/hostname
3. gedit will open your computer name
4. change it and enter the regular proxy order(for MITians)
5. Your net will work.
6. Be thankful you wont need to restart your computer in linux as in case of windows
