Xenocara comes with fvwm, cwm, twm.
OpenBSD defaults to fvwm
So, id you startx, without any ~/.xinitrc or /etc/X11/xorg.conf
you should have the fvwm with the console icon, the clock and the virtual desktop app.
If you don't, something went wrong in the install.

Note for -current users:
forgot to generate xorg.conf
Both mouse and keyboard azerty Belgian worked rightaway,
keyboard is el cheapo Rainbow made in China. Thumbs up!
Still need a xorg.conf on my server to tell him to use Xenocara and not dual display.
