When it comes to Ubuntu it gave lots of facilities to customize your own machine than other operating systems. So its time to make the best out of it, sometimes you will amaze if I say its giving the opportunity to change your start button. If you need to make your start button as you wish it only have follow some few easy steps.
The first step is creating your own image to replace with the Ubuntu default start button. Considering image type the image should be in .SVG format. Because the start button support SVG and it is a vector type image so it is scalable without having jaggies. You can create the image easily using Gimp(because Gimp Supports SVG). If you going to create this image using windows I think it will impossible to even open a SVG. So try to create your beautiful image using Gmip :). When you done with your creative artwork you should re size the images as it need. Considering the file structure of ubuntu icons it has few images sizes, like 16 * 16 , 22*22, 24 *24, 32*32. So we should create these size of images. But im not forcing you to create all of the sizes because it resize when we give any size, for now lets make a 24*24 .SVG image and save it start-here.SVG
Now you should find where these icons are laying on your system. Its easy you can find it at /root/usr/share/icons. When considering the icons it comes along with the theme. A theme can compatible with one or more icon themes. When you stepped into icons directory you can see many icon themes with various names eg:- Humanity, Dust Sand, Humanity Dark, Gnome etc. Next you should find what theme you going to use and its default icon theme. You can find it by
1. Right clicking on your desktop and go to Change Desktop Background
2. Select the theme that you need to custermize and click on custermize button
3. Then you can make sure what is the default icon theme.
By knowing the default icon theme
1.Open usr/share/icon folder with sudo (try "sudo nautilus" on terminal, this will open a GUI with root permission)
2.Than open the icon theme that you need to change.( eg. Humanity)
3.Inside humanity go to places directory(this will shows some folders with numbers, those are the folders that contains images with the relevant size).
4.Now go to each folder and search for Start-here.svg and if it is there replace the image that you have created before.
Now it show time...... Change the theme and see the new image is applied. If it is have fun with your own start button.
There are many many more things that you can do using this icon folder. Because you can replace any of the icons according to your choice. So you can say bye bye.. to any icon and you can welcome any icon that you love. Try something new and have fun with Ubuntu :) .
