Tue Apr 30 14:23:43 2002  Owen Taylor  <otaylor@redhat.com>

	* gdk/x11/gdkdisplay-x11.c (gdk_open_display): fix
	problem with finalizing non-initialized fully display
	when failing to open display.

	* tests/testxinerama.c: Xinerama test case from
	multihead branch, with some cleanups. (Start even
	if there is only one monitor, for one.)
