What does it mean "this driver is not activated" ? Because it looks a lot 
like one of the top two "bugs" of GridFlow, which is a strange interaction 
between GridFlow, C++, and an ATI driver (the OpenGL part thereof). Claude 
found the solution:

But I would very much like to know how to fix this permanently, because 
you can't make people have to jump through hoops that much to get 
something running.

(The other top two "bug" of GridFlow is that it uses a lot of stack for 
speed, yet the default maximum stack size is dangerously low).

With gdb you can get a better (more detailed) backtrace. I never used 
dmesg for those things.
