This is a setxkbmap bug fixed in 1.3.4 which is in -HEAD. See:

https://github.com/NetBSD/xsrc/blob/trunk/external/mit/setxkbmap/dist/ChangeLog#L39

which says:

    Be more careful about querying randr

    Check for extension version and number of outputs:
    XRRGetScreenResourcesCurrent was added in v1.3.  Also, there's no
    guarantee it returns any outputs, and we don't want to die with a
    BadRROutput error.

The relevant fix is this line:

https://github.com/NetBSD/xsrc/blob/trunk/external/mit/setxkbmap/dist/setxkbmap.c#L1106

Yes. Also just running this: `xrandr >/dev/null' in ~/.xinitrc, but, the correct
fix is in setxkbmap-1.3.4.

Compile the newer setxkbmap in -HEAD, or just extract the binary from the
xbase tarball. That works too.
