I have 11.10 64bit installed on my Lenovo s205. When I install 2G (confirmed by the BIOS), "Systems Info" only sees 1.6GiB, and when I install 3G, it only sees 2.6GiB. If seen some pages suggesting I run
sudo apt-get install linux-generic-pae linux-headers-generic-pae
after first calling for update, but I get the reply that it is impossible to install this. It might be that these post refer to previous releases, and I get the impression that this is more for people who have installed the 32b version, but is there anything I CAN do?
