The problem lies in an obscure specification called X. Some people tried 
to resolve issues like this one with a thing called, IIRC. "wasteland" 
or something like that anyway, but that was even worse.

Unfortunately that impedance in the XOrg spec has to my knowledge not 
yet been satisfactorily been sat down in a pub on a cold afternoon and 
had its googlies reorganized. In short, if you do find a solution it may 
work at your house here there somewhere most times other times and 
frequently not just when you want it to. In other words, it would be 
really nice if one day the X-men all sat down and decided what they 
really truly meant when they wrote all that unintelligible garbage, or not.

But I regress (possibly I meant something else there?).

mint is my second most hated distro! So there. It is the worst example 
of how to do things the easy way even if that means screw any common 
programs that are just too "hard" to get working, and the WORST forum I 
have ever seen. "You just need to do it our way you cretin!"

shutter is what you need. AFAIR there is an API, I've just never needed 
to use it.
