Maybe I don't have swap configured properly:

thufir at tleilax:~$ 
thufir at tleilax:~$ swapon -s
thufir at tleilax:~$ 
thufir at tleilax:~$ sudo fdisk -l

Partition table entries are not in disk order.

It's dual-boot.  I'm going to look into that swap command.  I'm inferring 
that because it doesn't return a result, swap might be off.



thanks,
