Re:DirectFB Inherently Insecure?

[RelentlessWeevilHowl]

Your X server also needs root access, and for much the same reasons. X needs to muck with the registers on your video card, for example. Nowadays, there's a little setuid program called "XWrapper" that gets access to everything it needs, then drops its privileges and loads the main X server on top of itself.

There is at least one project (KGI) that attempts to rationalize all this. It puts the privileged functionality in kernel space, then exposes it all in a safe manner. Linus has not been receptive to this design in the past, preferring the X mechanism.

Re:GDK vs. GTK

[ambrosius27]

Not exactly. GDK is an *abstraction* layer with multiple backends, the X11 one being the most prominent. To quote from the GTK/GNOME developers' website: "Instead of directly building on top of the X Window System, GTK+ introduces an intermediate layer, GDK, which isolates GTK+ from the details of the windowing system. This simplifies things for the programmer and increases portability." See the webpage. Through GDK backends, GTK has been ported to MSWindows as well as DirectFB(see also here).

I hope that helps.
