There wasn't a request about "free", but I was trying to find out what sort
of swap you had, and whether you have a "resume" option in the grub boot
options. That doesn't matter now, because "free" makes the problem clear.
My email shows 3 threads

incompletely thinking it was a resend. I apologize! Thanks for your

The above is with 5 desktops with at least 1 very big application and a
dozen small applications and including VNC.
So you need a bigger swap partition (or perhaps just an extra one - I'm not
sure if hibernate can handle split partitions).
You have ~1.4GB of memory in use, and ~0.8GB of total swap space. Some
compression occurs, and probably some memory that is known to be
discardable will be left out of swap altogether, but there's still no
chance that you can cram the memory being used for all that into your swap.
You've probably been misled by suggestions on the web that if you have so
much real memory, you don't need a large swap space. And for normal
operation, that's true, because if you have more physical memory than you
ever use you won't use swap. But since hibernation essentially works by
swapping out everything that's currently running, you need _at the very
least_ as much swap space as you have physical memory.

Thanks for identifying the solution to my problem. I stayed quiet
until you were finished with the others and I was trying to figure out
a way to deal with my situation (too little swap). I have included
directly below a lot of system information followed by the question
"Also, if I can use this tar backup on /media/sdc1 what would be the
command lines to prepare Ubuntu on /media/sdc1???????????". If you
choose to help me you will have to wade through this information. The
overall idea is not to scrap the present dual boot Ubuntu/XP
installation but rather to create a clone Ubuntu of the present one on
the same machine and with maximum swamp. Please read on if you can
spare the time to help me. If this turns out to be complex my response
time might be one or two days while I try to get my head around the
issues. Thanks.
I have freed up one of 5 hard drives (approx. 250 GB) on the dual boot
Ubuntu/XP system.
I did the following backup on Ubuntu:
sudo -s -H;cd /;tar -cvzf /media/sdd1/backup-Fri02May2008.tgz
--exclude=/proc --exclude=/lost+found
--exclude=/media/sdd1/backup-Fri02May2008.tgz --exclude=/mnt
--exclude=/media/cdrom --exclude=/media/cdrom0 --exclude=/media/floppy
--exclude=/media/floppy0 --exclude=/media/sda1 --exclude=/media/sda2
--exclude=/media/sdb1 --exclude=/media/sdc1 --exclude=/media/sdd1
--exclude=/media/sde1 --exclude=/media/sdf1 --exclude=/media/sdg1
--exclude=/media --exclude=/Mted-cic2ext --exclude=/Mted-CICERO
--exclude=/Mted-CICERO-D --exclude=/Mted-CICERO-F
--exclude=/Mted-market --exclude=/Mted-molly --exclude=/sys /
One of my questions -- given the above backup -- is: Can I use this
empty hard drive to install my present Ubuntu using the backup? Ubuntu
on this dual boot system is on the XP C drive or from Ubuntu's
perspective the SDA3 drive with SDA1 and SDA2 for the XP. Here is the
mount info:

So the hard drive I would prepare would be: /media/sdc1
Another question: Would there be a boot problem because using this hard
drive as I understand (from away back in time) the boot system and the
active hard drive would be on SDA (or from the perspective of XP, the C
drive.) I am not sure how grub would handle this situation (3 instead
of 2 boot systems with one on a currently "none active" hard drive.

Also, if I can use this tar backup on /media/sdc1 what would be the
command lines to prepare Ubuntu on /media/sdc1???????????
Thanks, Ted.
