I am a newbie, so the problem is likely due to my miscomprehension rather than anything that you have supplied on this forum.
Maybe you can point out to me what I should do to make this work. I downloaded usplash-maker and installed nautilus (as it was not included in my Kubuntu 8.04.1). Then I right-clicked on my image file and then selected and left-clicked on usplash-maker. The program starts to run - the first small screen pops up telling me what the program is going to do. After I click to continue the same pop-up screen appears again and I click to continue again, and then the process continues until the last screen which tells me that it is 'Processing' (but nothing else happens on that pop-up) and then within about 3 seconds the program ends and there is no resulting '.so' file as expected. I tried this several times, but nothing happens.
Can you help me out please.
