So I'd have to edit my .Xinitrc every time I want to switch.
But at this point, installing LightDM or similar would be easier.
Hey thanks for the link, it makes me think I need to comment my .xinitrc file
(and others).
This helps understand what happens.
It makes me think that I want to write a startup installation script, just
like Crunchbang had (has, I think it still exist with a new name).
But I'm not completely done building the system that fits my needs.
Hopefully it won't take me too much time anymore.
