MMmh... I have found where DPMSDisable come from, it's in libXext.a.
So, i link Xext by typing this :

gael at Kubuntu:-$ rebuild main.d -L-lXext -clean
gcc ./_main.o ./detris.engine.o ./nmd_gcstats.o ./detris.defines.o -o
main -m32 -Xlinker --start-group -lphobos -lSDD-derelict-sdl
-lSDD-derelict-util -ldl -lSDD-derelict-util -lXext -lphobos -lpthread
-lm

But i still get the error... :(
