System: NetBSD ursula.wongs.net 1.5.2 NetBSD 1.5.2 (GENERIC) #0: Sat Nov 17 17:21:16 EST 2001 toor@ursula.wongs.net:/usr/src/sys/arch/i386/compile/GENERIC i386


>Description:

SDL, the Simple Directmedia Library, can normally use XFree86's DGA2
extension to access the raw frame buffer and perform double-buffering.
However, the configure.in file for SDL-1.2.2 doesn't call CheckDGA if
the OS is NetBSD, and so SDL compiled for NetBSD has to use the much
slower X11 video driver.

>How-To-Repeat:

Install SDL from devel/pkgsrc. 

Install apla from pkgsrc/graphics. (Actually any SDL program, such as
testsprite.c from the SDL cvs tree, will work). 

Su to root, set the SDL_VIDEODRIVER environment variable to dga, and
run apla:

	    su -l
	    setenv SDL_VIDEODRIVER dga
	    apla "somemovie.avi"

SDL will complain that there is no video driver available.


>Fix:

Patch configure.in to run CheckDGA when the OS is NetBSD. Here is a
patch which replaces patch-aj:
