this patch by Diego Pettenò flameeyes@gentoo.org for SDL-1.2:

The attached patch applies over latest ~arch SDL version, and allows to use the
xinerama support to launch an application full screened on the head "0".

The SDL_VIDEO_FULLSCREEN_HEAD environment variable sets the head on which the
full screen will be displayed, but if you set it to 0, the code simply ignores
it as unset. My patch changes the unset value to -1, so that the 0 value can be
used correctly. Without this, trying to get fullscreen on head 0 would get the
same result than not having xinerama enabled at all.

SDL-1.3 doesnt seem to have any code like this, but it's still good for SDL-1.2

I confirm. This bug exists in Ubuntu 8.10 version. It prevents SDL applications from running properly on first Xinerama screen, making them useless for me.

This happens because set up Xinerama mode is overwritten in XVidMode code block. The patched version works properly. Please apply this patch to the upstream version.

Tagging this bug with "target-1.2.14" so we can try to resolve it for SDL 1.2.14.

Please note that we may choose to resolve it as WONTFIX. This tag is largely so we have a comprehensive wishlist of bugs to examine for 1.2.14 (and so we can close bugs that we'll never fix, rather than have them live forever in Bugzilla).
