I think you are mistaken.

Try it without a login manager. Just run "X :1", either from a terminal
or a console. The 1 assumes you're only using display :0; increment it
if necessary. That should start X with no clients at all, and the
eye-watering default background. Press ctrl+alt+backspace and it will
go away - it will not restart.

Thanks for looking at this!
