I have just installed xubuntu 14.04 and elected to do the encryption (not the full disk, just the ubuntu part and my home dir). I realized however that I failed to create any swap space. When I run gparted it shows just two partions sda1 (/boot) and the rest of my SSD sda2. But gparted does not list how much of sda2 is used or unused. why?
I'm not sure if I can at this point create any swap space, because of the encryption during the installation. What should I do, and how do I do it with gparted. Gparted does not seem to let me resize the partitions.
my gparted window looks like this:
- Partition File Sys Mount pt Size Used Unused Flags
- /dev/sda1 (keys) ext2 /boot 243MiB 53.17MiB 189.83MiB boot
/dev/sda2 extended (blank) 476.7GiB --- --- (blank)
- Which partition should I try to change, and how (to create swap from it)?
- Is it not possible to alter a partition without corrupting the encryption?
I have 16GB of RAM, and I do use the machine for scientific computing.
