There are a few other questions here with a similar title, I followed the steps in each one but I'm still unable to resize my Ubuntu 11.04 partition using Gparted. When I right click on sda1, and choose resize, I am unable to add space to the partition, only subtract.
My apologies should this be closed due to being so similar to the other like questions.
sudo apt-get install gparted
