I have tried the advice here:
Puny geek including the last amendments.
and here
Askubuntu including the advice further down for 14.04

I am running Xubuntu 14.04 on an older system. I just upgraded the memory for what it is worth.

But none of them work. I realise this has been asked before but as no response fits my case please understand why I am posting what is a question often asked.

I can work with swap but when rebooting it seems to ignore and I have no swap again. I have amended the /etc/fstab and /etc/cryptab and /etc/initramfs-tools/conf.d/resume and nothing works.

Short of just accepting a suboptimal system I don't know what to do.
