Hi Ian, Actually, I'm not using X. The app that produces the bitmap is essentially ghostscript converting from ps to bmp using the bmp16m filter. When gs runs, the application (which displays graphical data directly using the frame buffer, under QT) stop updating.
So gs is not actually drawing a bitmap but simply creating one in memory or a file somewhere.
That is why I was looking for a kernel type solution.
If gs is not drawing then a kernel solution is exactly what you need.
