Brian, x11-16 is sometimes 2 times faster than regular x11, it depends on what you are doing. There is no fb-16 yet (willing to write it? ;-)). However in your case it's much slower, that shouldn't be the case. It would be great to try "expedite" with -e x11 and x11-16 and report, at least, the first 4 tests values. As for framebuffer an x11, they should be almost the same. We just tested on Freescale's imx31 at 480x640 and it's not that difference. X11 is not as bad as people claim. -- Gustavo Sverzut Barbieri http://profusion.mobi embedded systems -------------------------------------- MSN: [EMAIL PROTECTED] Skype: gsbarbieri Mobile: +55 (19) 9225-2202 ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ enlightenment-users mailing list enlightenment-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/enlightenment-users
