    I think if you need just mp3 and no complicated frontend with lots of graphics, you can get about 5+5 = 10 secs till you hear sound without any hibernation. 5 secs for linuxbios, 3 for kernel+ 2 initrd.

    I'm running it on a laptop, so the boot time is pretty much moot. I'd say it's 20-30 seconds from boot, a few seconds for resume.

    You might find this article interesting. Basically on using make to run some of the init stuff in parallel to speed up booting.

    Im writing a directfb app for my carpc, because i cant stand X and its startup time, and its unnecessary overhead in a car pc.

    Might have a look at my first screenshot:
    http://xs.to/xs.php?h=xs54&d=05451&f=DFBAMP_sshot.png

    Its still under development. DirectFB is a thin library on top of the framebuffer, easy to use (for me), and has a sister library for sound.
    Right now (yesterday) i just managed to get away from mplayer as a backend and play music directly thru my program.
    Future plans:
    Video playing, GPS, file manager, wifi, and replace initscripts, i guess hardcoded c is way faster than all-guessing bash scripts

    My guess for startup speedup is remove _everything_ unnecesary out of the kernel (networking, anyone?), and using a BSD style rc initscript.

    Pretty cool. I was only vaguely aware of DirectFB. Have to check into it.

    As far as replacing init scripts with compiled versions, I doubt it would be worth the effort. I think most of the overhead on a relatively simple shell script is process creation.

    Thats cool steele. I'm actually in the middle of working on a gui toolkit that runs on X, DirectFB, OpenGL, and VFD Modules. You can see a very simple screenshot by going to http://www.nrrds.org/lbox/ and clicking screen1. What are you going to use to write your interface? I know the new version of QT will run on FB.

    Either of you know how well SDL plays with DirectFB?

    BTW, timed out trying to reach your url.

    Hey, you writing a toolki for dfb? You're welcome! I am only aware of LiTE, which is under development but i havent seen it yet. I have managed to get gtk on directfb tho, but its not very good.
    I am not using any toolkit, i just wrote some very simple stuff for use in my app. Buttons, and the playlist for now.
    Your screenshot doesnt load btw , im interested in seeing it

    Shotgunefx, youre probably right with the overhead i didnt actually research much about that

    What you really want to check out is PyGame, which is built on top of the Simple DirectMedia layer, which is a cross-platform library that supports multiple hardware platforms, including Windows and the Linux Framebuffer.

    The frontend I'm writing is using Perl and (SDL) Simple DirectMedia layer. My biggest gripe is getting fonts to work properly. Took quite a bit and still have some problems with transparancies.
