As root, in the file /etc/default/grub, find the line that sets GRUB_CMDLINE_LINUX_DEFAULT, and take out the word "quiet". Then run update-grub, and reboot. You should see a lot more messages. Then shut down again, and watch. N.B.: A mistake here could clobber your system badly, so be careful. -- Does anybody read signatures any more? https://charlescurley.com https://charlescurley.com/blog/
