With hibernation configured it will also be necessary to edit {{ic|/etc/default/grub}}. Find and remove option {{ic|<nowiki>resume=UUID=...</nowiki>}} or replace the UUID with a new proper value. In the example above, we would remove this text: | |||
resume=UUID=c2430cf1-8ea9-4422-a5c5-5a38779194c3 | |||
Then run: | |||
sudo update-grub | |||
If removing hibernation entirely then also delete {{ic|resume}} from the {{ic|HOOKS}} line in {{ic|/etc/mkinitpcio.conf}} and run: | |||
sudo mkinitpcio -P | |||
