How do I delete hibernate data

[kevpatts]

I accidentally hibernated XFCE on Friday when leaving work. Now every time I log in all my previous apllications from that hibernation load up, even if I close them and log out.

Not even that but there are no title bars on anything and I can't change windows, move windows, maximise/minimise, use shortcuts or really use my PC at all any more.

How do I delete the hibernation data and startup normally? I've already tried "noresume" kernel param, "swapoff-a; mkswap /dev/sda1; mkswap /dev/sdb1; update-initramfs -u" and I've editted /etc/fstab to explicitly state those partitions as the swap partitions, but no effect so far.
