I manage an education lab with edubuntu 12.04. Since Aprile 2013 I have a strange issue: all the PCs work good except one that is able to boot but it stops in a strange loop as if lightdm isn't able to load the login screen. I tried many approaches to fix the problem (installing OS again, changing the NET cable, changing the PC) but I haven't been able to solve it.
Someone fan help me?
