Dell Laptop Inspiron 17" 3793 brandnew - after Ubuntu install always boot failure to grub

its a problem with tpm-module

this:

sudo cp /etc/grub.d/40_custom /etc/grub.d/06_notpm
sudo bash -c 'echo "rmmod tpm" >> /etc/grub.d/06_notpm'
sudo update-grub

thanks a lot to: @Dayworker (from dell-forum.de)
