Hi all,
This what i did
Edit lxdm configuration file
cat /etc/lxdm/default.conf
Change this line
bg=/usr/share/backgrounds/background.jpg
Restart lxdm daemon
systemctl restart zentyal.lxdm.service
Download a PIC to use as background
wget
https://cdn.hipwallpaper.com/i/86/48/HugvwJ.jpg -O /home/administrador/HugvwJ.jpg
Change this file as i wanted
I want to see IP address of this server at login screen
convert -font "/usr/share/fonts/truetype/ubuntu/Ubuntu-M.ttf" -pointsize 36 -fill yellow -draw "text 640,150 '192.168.0.246'" /home/administrador/DYBfT7.png /home/administrador/BGDYBfT7.png
Copy this new Background file to its place
cp /home/administrador/BGDYBfT7.png /usr/share/backgrounds/background.jpg -f
systemctl restart zentyal.lxdm.service
From now on, i can see my new background an my Server IP Address at login screen
Thanks, regards
Saludos
