I upgraded to oneiric Beta2 for some reasons I prevously explained. Now I cannot use LightDm. GDM works fine but cannot use Lightdm. When booting past Grub the message is checking battery state...[ok] and it checks forever. Is there a work around?
I tried the command sudo dpkg-reconfigure lightdm which gave the result :
dpkg-maintscript-helper: warning: environment variable DPKG_MAINTSCRIPT_NAME missing dpkg-maintscript-helper: warning: environment variable DPKG_MAINTSCRIPT_PACKAGE missing
