Please run below command to disable gdm first,

            sudo mv /etc/init/gdm.conf /etc/init/gdm.conf.disabled

then press 'ctrl+alt+F1' during ubuntu boot to enter console.
After login to console, please type below to enable kernel
message switch:

            sudo echo 9 > /proc/sys/kernel/printk

then run 'reboot' to get the kernel log.

After completing the process above, you can restore your gdm
configuration to enable gdm again.

Thanks,
