I am using Ubuntu 13.10 on a computer with 3072 MB RAM and 20 GB swap. It is an HP G62 laptop which overheats pretty regularly.
When I type free -mt
in the terminal the output is:
free -mt
total used free shared buffers cached
Mem: 2873 2741 132 0 9 1084
-/+ buffers/cache: 1648 1225
Swap: 19529 42 19487
Total: 22403 2784 19619
Note the free memory: 132 MB!! The maximum free memory I have observed is 750 MB directly after startup. Whats happening???
also note the temperatures:
