What is DirectFB
 
Dear all.

I've been read here and there about DirectFB, but still not clear.
Is it posible to replace X11 with DirectFB for desktop ?
* Can it run any windows manager ?
* what apps can it run ? I saw it supports GTK2+
* Do we need to compile all apps with directFB instead of X11 ?

Thanks

DirectFB is a thin library that provides hardware graphics acceleration, input device handling and abstraction, integrated windowing system with support for translucent windows and multiple display layers on top of the Linux Framebuffer Device.

And here is a link to the Documentation page. I found all of this by typing "directfb" into www.google.com

Dear XavierP.

Thanks for your reply and the link.
However, forgive my newbiness.
I asked here because I was confused there, reading that for-expert-howto.
For example, the definition you gave ... too many expert vocabularies there ..

I have look at the FAQ too.
It does not answer my simple questions.

Do we use it like XFree86 ?
Launch directfb, then WM, then applications ?

I read on XFCE4 milist,
somebody said he was using xfce4 with directfb.
How can he do that ?


Allright.
Sorry again if this question is too newbie to be here.

I have to admit that I know next to nothing about DirectFB. At first reading, I thought it was a window manager, but on second reading it appears to be a replacement or addition to Xfce.

Also, reading through again, it looks like (or at least that's my reading of it) that it's not totally ready - they are still ironing out some of the bugs. If you intend installing, I'd make sure that you have your important data backed up.

I think this needs to be thrown open to the rest of the board - maybe someone who knows more than I can answer.

You need a third reading, probably more :D

not sure, but the wordings make it sound like it's a replacement for X (especially when they talk bout device dependence and HAL). apparently, it's more efficient than XF86?

and hey, no support for nVidia cards (which disqualifies me immediately). :)
