[gdm-list] Fwd: Autologin and multiseat

[Darryl Bond <darryl bond gmail com>]

Guy,

Thanks for the script. I have tuned it up a bit, you may be interested. 

My use case is a kiosk that creates a user based on the $DISPLAY and removes them when they log off. The password is a one time generated password.

First I had to revert to the fallback login box so I could remove the userlist.

mv /usr/share/gnome-session/sessions/gdm-shell.session /root/

cp /usr/share/gnome-session/sessions/gdm-fallback.session /usr/share/gnome-session/sessions/gdm-shell.session

gconftool-2 --direct --config-source xml:readwrite:/etc/gconf/gconf.xml.mandatory --type bool --set "/apps/gdm/simple-greeter/disable_user_list" "true"

Then Copy /etc/gdm/Init/Default to :0

# cd /etc/gdm/Init

# cp Default :0

and add to the end of :0

/etc/gdm/Init/autologin.sh&

Link the number of displays required

ln :0 :1

ln :0 :2

...

Create the autologin.sh script 

vi /etc/gdm/Init/autologin.sh

#!/bin/bash

PASS=$(openssl rand -base64 32)

PW=$(perl -e 'print crypt("$PASS", "aa")')

exec >/var/log/gdm/${DISPLAY}-autolog.log 2>&1

LUSER=kiosk$(echo $DISPLAY | cut -c 2-)

if [ -d /home/$LUSER ]

then

# delete the user and home directory

/usr/sbin/userdel -f -r $LUSER

fi

/usr/sbin/useradd -m -k /home/admin -p $PW $LUSER

sleep 1

xdotool type $LUSER

xdotool key Return

sleep 1

xdotool type $PASS

xdotool key Return

Make it executable

# chmod +x autologin.sh

Fix Selinux file labels

# cd /etc/gdm/Init

# chcon --reference=Default :0 autologin.sh

Test by logging out of display, it should log back in automagically.

Thanks

Darryl

sorry typo:
add at the bottom of  /etc/gdm/Init/:1
before exit 0:
