The problem is that the installation uses LVM. At best, you only 
extended the "physical volume" (LVM container) in /dev/sda5. At worst 
you only extended the partition /dev/sda5.

Steps :

1) Extend the PV to the new partition size (will do nothing if not needed) :

pvresize /dev/sda5

2) Check available space in the "volume group" :

vgscan

3) Display "logical volumes" :

lvscan

4) Extend logical volume(s) as desired (assuming extN) :

lvextend -L <size> /dev/<vg>/<lv>

5) Resize filesystem(s) :

resize2fs /dev/<vg>/<lv>
