As I understand it the display manager asks you to pick an xsession
and log in.
I'm running icewm
on Ubuntu 22.04 an old machine and just need it to start up and start icewm
automatically -- no need for display managers or passwords.
I've switched from gdm3
to ligntgdm
(xdm
doesn't work) but can I remove the display manager completely since it is entirely useless?
