I disagree with that sentiment. X.org works fine on embedded platforms, and is used on such systems with success. In fact I have built a system on top of a touch screen with Xorg, including a full XUL based browser. My storage space limitation was 64MB, so I stopped optimizing for that after I got to a 43MB squashfs system. After removing XULrunner and GTK+ and the obviously related thing from that image and squashfs'ing again, its size becomes 24MB for me, without any hard trimming at all. With building from scratch, without the less obvious GTK+ and XULrunner dependencies pulled in, and some slightly more trimming, I'm confident less than 15MB is quite achievable. So I do not see why X windows would be inappropriate for embedded platforms, at least when looking at storage space limitations. For that the touch screen handling would be very easy from Xorg, and depending on the graphics chip, might even get considerable graphics acceleration that is not possible with DirectFB. That said, I can not offer any free help in building it small. Just making sure X11 isn't thrown out from the list of possibilities without a good reason. > try using directfb But sure, DirectFB is an option as well, especially if you are developing for a platform that provides graphics acceleration on top of DirectFB, but not on top of X11. > port of fltk (if it's still working...) or take peek at Xfast and > clones... _______________________________________________ xorg@lists.freedesktop.org: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: http://lists.freedesktop.org/mailman/listinfo/xorg Your subscription address: arch...@mail-archive.com
