It's not exactly a question and more of a discussion.
I found very less graphics application being developed for linux system. I'm not really fond of graphics programming and have a very little knowledge about it. Can any one suggest me that whether linux lack in ghraphics support? or something else is the reason for graphics application in linux?
What are you looking for and not finding?
Applications pretty much have to be graphical and interactive in Windows, with its lack of effective shells.
Despite all the bells and whistles from window managers and o/s hooks, under it all is Xwindows in all LINUX/UNIX I can think of, except maybe Apple junk. There are many very accessible tools for using XWindows. I recall one that let you compose graphic files in text and then convert them to popular image file formats. It can light up all the pixels in all the colors. Ubuntu feels like funny Windows. Browsers and JAVA give you access to the graphics. What do you want from a graphics environment?
