I recently increased space and swap space for ubuntu on my laptop. Even though the space got increased, my swap is not being recognized. It is showing as 0 bytes of space. However, interestingly, when I boot from live cd and click try ubuntu, space for swap is being recognized.

What can be causing this weird problem?

Normal Boot:

bhaarat@bhaarat-laptop ~ % free

Live CD Boot
