Can you please provide the full boot log from the system boot  where
you do not get the graphical login. You might be able to access the
log online if the system is accessible via ssh or retrospectively from
the system journal.

Additially please provide the information gathered by 'reportbug
kernel' so we gather inforation on HW, system configuration, loaded
modules.

Regards,
Salvatore
