Cdm

A console based display manager for linux/bsd.
Written in bash.

NOTE:

interestingly, since xorg is not running yet, you may be able to change the xorg.conf that is loaded for each entry..

Locations

/etc/cdmrc	system config
~/.config/cdm/cdmrc	user config
/usr/share/doc/cdm/themes/*	themes
/usr/share/xsessions/*.desktop	default installed xsessions

Usage

Default

After copying ~/.profile (see below),
simply login on TTY1 and you will be provided with login choices.

cdm automatically loads entries from /usr/share/xsessions/*.desktop, but you can provide your own instructions.

Manual

cdm ${rcfile}  # test cdm interactively

Configuration

Enable CDM

# copy .profile, which will run as soon as you login on the console.
cp /usr/share/doc/cdm/profile.sh ~/.profile

Or alternatively append it to your .profile

# To avoid potential situation where cdm(1) crashes on every TTY, here we
# default to execute cdm(1) on tty1 only, and leave other TTYs untouched.
if [[ "$(tty)" == '/dev/tty1' ]]; then
    [[ -n "$CDM_SPAWN" ]] && return
    # Avoid executing cdm(1) when X11 has already been started.
    [[ -z "$DISPLAY$SSH_TTY$(pgrep xinit)" ]] && exec cdm
fi

Menu Choices

cdm is configured with 3x arrays.
entries in each array at the same index refer to the same login choice.

# (~/.config/cdm|/etc/)cdmrc

# startx ${THIS_COMMAND}
binlist=(
    "/bin/zsh -i"  # console
)

# name of each choice
namelist=(
    "tty" 
    "i3" 
    "openbox"
)

# if choice requires an X-session, or is a console
flaglist=(
    C
    X
