I boot, I see, "The device mapper for

Waiting has no apparent effect; M does
nothing.<br>

Gnome-system-monitor shows swap as not
available. Gnome-disk utility shows the
partition as inactive and when I Activate
it, the swap status changes immediately to
available.<br>
<br>
After a reboot, I get the same message at
boot, swap is not available and is not
active, according to Gnome-disk.<br>
<br>
I'm running Xubuntu 14.04 and updates are
current. But, I've seen the same message
at boot on another PC running Xubuntu
12.04.<br>
<br>
Luckily, Linux manages memory memory quite
well so swap is seldom called into action,
and, I don't hibernate - just suspend or
shutdown.<br>

Solution? <br>

Marcos: did not work. I tried it last night. I did a little more
research and found this is very likely related to a bug,
<a class="moz-txt-link-freetext" href="https://bugs.launchpad.net/ubuntu/+source/cryptsetup/+bug/1153661">https://bugs.launchpad.net/ubuntu/+source/cryptsetup/+bug/1153661</a><br>
<br>
In short, it appears to have been around since ver. 12.04 with
various attempts to cope with little success.<br>
<br>
In the short-term, it appears to me that the best solution is to
dump encryption of /swap and go with a non-encrypted swap. BUT, I
don't know how to do that!<br>
<br>
More comments:<br>
<br>
The encryption of /swap appears to be a byproduct of opting to
encrypt /home during install of Xubuntu. This happened without my
explicit invoking this option during install on two different
systems.<br>
<br>
As noted by others, the UUID for encrypted swap is not correctly
identified in /etc/crypttab as well as in /etc/fstab.<br>
<br>
Some suggest that the error is related to having installed from a
thumb drive, which is what I did.<br>
<br>
Puny Geek suggests updating /etc/initramfs-tools/conf.d/resume. That
file does NOT exist on my 14.04 install.<br>
<br>
As others have noticed, some fixes work for a current session but
don't survive a re-boot. I had this experience by "activating" the
/swap partition with the Disk Utility, previously known as
"palimpsest" under 12.04.<br>
<br>
I concluded that, since this bug has been long-standing and others
have not been successful in fixing it or having a lasting
work-around, I'm not likely to be successful either. Hence the
conclusion of living without it being encrypted is a nice work
around. I encrypt /home on my portable devices to protect personal
info if it is stolen. My guess is that it's unlikely for unencrypted
info to be compromised because it's unlikely to sit in /swap and be
read by a nefarious operator.<br>
<br>
Thanks to all who thought about this.<br>

Oh: here's one I did not try: treating this as a timing error (also
discussed elsewhere)<br>

<br>
Other thoughts:<br>
Try creating /etc/initramfs-tools/conf.d/resume with the correct
UUID and go through Puny Geek's approach.<br>
Hope for a solution in response to bug report.<br>
<br>
p.s. All of this fiddling around is what I anticipated when
attempting a solution and why I put it off!<br>
