The command ribbackbone merely enables the simultaneous display of both ribbon and backbone atoms. You would still use display/~display to control which of those backbone atoms are shown, for example:
disp :110.a at o
As explained here,
the default ribbon is smoothed and does not go exactly through the atom positions. That is why by default they aren't shown at the same time. However, if you want ribbon that goes through the exact CA atom positions, use the cardinal spline instead of the default B-spline, for example:
Then the ribbon is not as pretty, however. There are some smoothing options for a compromise, as described in the help page elicited by command "help ribspline"
