The gparted version in the VL repositories is 0.3.3 I believe whereas the latest is 0.3.4.7. Depending on what file system (i.e. ext3, reiserfs, XFS) your /home partition is formated with the VL version may not allow you to grow the partition. The latest from the gparted website (http://gparted.sourceforge.net/livecd.php
) will allow you to grow all that VL allows you to setup during installation. Thus getting the latest live CD would be my recommendation for you. Also as lagagnon has pointed out using the GUI makes it much easier.
