I installed tuxonice in Ubuntu 13.10 and everything works as intended (resuming, hibernation). The only strange thing that happens is that it get a "Resuming from /dev/disk/by-uuid/..." message when I just boot up my computer that I usually only get when my computer really resumes from hibernation. The only diffrence between the two situations is that on a normal boot the dots on the splash animation change and on resuming are just static white.
How can I remove the unneeded "Resuming..." message on a normal boot?
You can't. Or more like is not advisable. That message is from the kernel ring and if you disable it you will be disabling all kind of important messages that could appear. So, if everything is working as intended and
quietis set in the boot arguments, leave that message there!
