When I attempt to change the theme for Entrance using using the command entrance_edit –theme <path to theme file>, entrance & x will not start. Fortunately I have Gdm installed as well & am able to boot from the Elive CD, then was able to edit /mnt/(my partition)/etc/X11/default-display-manager from entranced to gdm.
This allowed me to log back into my account after rebooting. To get it back to normal I have to completely uninstall all entrance files, reboot, log back in & then reinstall the entrance files & reboot again & entrance is back working. but how ever I am not able to change the theme for entrance using the entrance_edit –theme <path to theme file> command.
