It's a 3 day old install of Ubuntu 13.10

I set my partitions up correctly beforehand with Gparted(you'll have to trust me on that) swap partition was formatted as linux-swap and given 6gb of space. My RAM is 6gb also.

In Gparted now my swap partition's file system is 'Unknown' and there is an exclamation mark after the '/dev/sda6'.

Immediately after installing Ubuntu, while booting, I would get the message that there was a problem with '/dev/mapper/cryptswap1' not being ready to mount or not being available. I followed this very short tutorial, essentially creating a new swap and reformatting. After this I no longer get the error message while booting, but my swap partition still doesn't appear to be working according to Gparted. Any help much appreciated.

/dev/sda5 is root
/dev/sda6 is swap
/dev/sda7 is home

Try to put in /etc/rc.local

sudo nano /etc/rc.local

swapon /dev/sda6

Maybe this solve your problem
