Most Linux based pdf viewers work great with static pdf forms (made with Scribus or not) unless
the form has some background scripting for stuff like math within the form. Adobe reader for linux is way outdated and too heavy of a program. I found that dragging the file to a blank tab in Chrome will allow the scripting to function. I've been struggling with this for years until I had a flash and did a face-palm after trying it. This is also a great way to test forms made in Scribus. Just leave the browser open, load the file, edit, re-export, back to browser and refresh.. viola!
