Sounds reasonable, especially for an embedded system. If you have at least 16M you can make it work though. Just try a lightweight window manager like enlightenment instead of kde or gnome, then you will have ALOT less compatibility problems. > I have gone through a lot of Maillists which say I need to some GUI > Library or tools like > > GtkFB - does NOT use X11 > Qt/Embedded - Direct Framebuffer access and so on. > > I have a very basic doubt here.

You dont need any kernel modules per-se everything you want to accomplish is in userspace. As long as framebuffer is working don't touch the kernel ;) It sounds like you are coming from the windows world if you think you need to click an icon to make a GUI work. I haven't used those libraries per-se, but as long as you provide mouse and toolkit support you can launch firefox (for example if it supports Qt/Embedded) just by typing it in. As the prompt you will type my-app and if you install the proper support libraries it will use the framebuffer for rendering instead of the X server. This all depends on the application though. Since the majority of "GUI" apps are designed for X, then you may run into odd compatibility problems when not running them in X. You are on the right track, keep reading those mailing lists, install the libraries, find a compatible program and run it!
