Hello everybody. Some time ago I’ve had a computer with 4 GB of RAM and it’s had the Ubuntu 32 bits installed. Unfortunately the linux only accessed about 2.7 GB of RAM. To solve this problem, I’ve done that:
sudo apt-get install linux-image-generic-pae linux-generic-pae linux-headers-generic-pae
After that, I restarted the computer and was ready, more then 3 GB of RAM was accessed by Ubuntu.
That’s it. See you next time.
