I'm running Ubuntu 12.04 on an Acer Aspireone ZG5 and just plugged in 1g of ram on the motherboard.
I appears to be that the new memory isn't detected. Here's the free -m report;
The system is up to date.Code:~$ free -m total used free shared buffers cached Mem: 483 414 69 0 14 188 -/+ buffers/cache: 212 271 Swap: 2444 47 2397
Can you tell me why free -m doesn't show 1g of ram?
How can I fix it so that it recognizes it?
