You need to edit your grub configuration file using:

gksu gedit /etc/default/grub

look for the line containing β€œquiet splash” and change it like so:

GRUB_CMDLINE_LINUX_DEFAULT="splash plymouth:debug"

You might have other options there like kslar or vt.handoff=7 leave them in place. The important thing is to remove quiet and add plymouth:debug.

Save the file and then use:

sudo update-grub

Now when you reboot error messages appear on the boot screen plus a full plymouth log is located at:

/var/log/plymouth-debug.log

Good luck tracing down you errors!
