Switching between XFree86 & Xorg

To switch between the XFree86 X server & the Xorg X Server on OpenBSD simply delete the X symbolic link
rm /usr/X11R6/bin/X
& create a new symbolic link from your preferred X server to X
e.g for Xorg
ln -s /usr/X11R6/bin/Xorg /usr/X11R6/bin/X
or XFree86 SVGA
ln -s /usr/X11R6/bin/XF86_SVGA /usr/X11R6/bin/X
