[xubuntu-users] Problems Booting after 15.10-16.04 Upgrade

[Karagkiaouris Diamantis]

Dear John,

Have you installed the proprietary drivers for you machine in the 
previous installation before upgrade? That's the cause of many "black" 
screens in boot menu. If this is the case you must remove them and 
install the open source one. Also it would be helpful if you could check 
lightdm (the corresponding gdm) with the following command:

sudo systemctl status lightdm.service

Kind Regards,
Diamantis
