Description

I just bought a gateway convertible tablet and installed Gimp. Pressure sensitivity does not work. The pen works like a cursor but no pressure sensitivity. I've searched many forums and tried the fixes they suggest and have found no cure. Without this feature Gimp is useless. Do you have any fixes for this? I don't want to have to break down and buy "Photoshop". I did download paint.net and the pressure sensitivity works great immediatly from startup without having to set anything up. Just incase you wanted to contact them and see how they got it working.
