System spec check

The man in the computer shop who put Peppermint 8 on my Dell laptop said that I have 3 gig of RAM but sometimes I am getting a message saying I am low on RAM and my laptop slows down, so I reboot it. Could one of you kind guys do me a spec check please? I know there is some way I can find my specs but I have forgotten where to look!

What’s the output from:

inxi -Fz


free -m

Thanks Mark. Here you go:

You definitely have 3GB of RAM, but you’re starting to use the swap file.

You may want to set swappiness to say 10.

To do this, run:

sudo pluma /etc/sysctl.conf

add these 3 new lines at the end of the file

## Start custom swappiness setting
vm.swappiness = 10
## End custom swappiness setting

SAVE the file and exit the text editor.


Once rebooted, run:

cat /proc/sys/vm/swappiness

and check the output is “10

Which web browser are you using ?

Thanks Mark, it is 10. I’m using Chromium.

okay let’s see if that helps.

If you’re running out of RAM because you have loads of web browser tabs open at the same time … Firefox may be a better bet than Chromium.

I would have thought that 3GB of RAM should be enough! It’s not so much browser tabs but when I open up jpgs, access jpgs, save them etc. I prefer Chromium as it has all my bookmarks on it.

Well so would I (depending on use case), but it’s not the OS that’s using all the RAM.

Is it still lagging with swappiness set to 10 ?

and what’s do you have running/what are you doing when you appear to run out of RAM ?

Yes, still lagging and needing rebooting. As I mentioned Mark, it is when I am doing anything with images- uploading, downloading both. Is it possible on a laptop to add more RAM? Maybe I need to up it to 6GB!

I’m doubting if it’s a RAM problem now (unless you’re manipulating MASSIVE images).

What’s the output from:

free -m

whilst it’s lagging ?

And is this only whilst uploading and downloading ? … if so, can you define “lagging”, ie. do you mean just the up/download or the entire OS ?

arnabas@barnabas-Inspiron-1545 ~ $ free -m

barnabas@barnabas-Inspiron-1545 ~ $

No, just jpegs, and using picmonkey and accessing jpegs saved in my google drive! Well yes, it is mostly whenuploading and downloading and looking at sites that have pics like pixabay etc. Then the laptop will just say it has ran out of RAM and need rebooting.

Are you opening loads of tabs at the same time ? … and are many of them showing flash content ?

If your system was lagging when you ran this:-

arnabas@barnabas-Inspiron-1545 ~ $ free -m total used free shared buff/cache available Mem: 2967 1418 524 245 1023 1113 Swap: 3029 0 3029 barnabas@barnabas-Inspiron-1545 ~ $

it’s not a RAM issue.

I have only about 3-4 tabs open at any given time. Some might have flash, some might not-depends what I’m looking at. It always says I have low RAM before it freezes and I have to reboot.

Well you weren’t low on RAM when you ran that (you had over 500MB left and hadn’t even begun to use the swap partition yet) … so I’m confused.

Is it Peppermint, or Chromium that’s telling you you’re short of RAM ?

Yes, it’s very weird Mark. I dunno, next time the box comes up I will look and try and figure out where the message originates from.

The incidences of freezing are happening more and more- the whole laptop froze when I was watching a vid on you tube( had paused it whilst I popped to kitchen for a drink) and when I clicked to resume the laptop froze to such an extent that I could not even get the reboot tab to open, so I had to press the power off button, which took almost 10 mins to get to work and to re start the laptop.

Run memtest86+ from the GRUB menu, leave it running for a while and see if it throws up any memory errors ?

How do I do that Mark? Sorry I’m not au fait with stuff like that!

Immediately after you turn on your computer and the manufacturer logo disappears hit and hold the Shift key … you should be presented with the GRUB menu.

At the Grub menu you should see an option called “Memtest86+” … use the arrow keys to highlight it and hit enter.

If there’s no Memtest86+ option, choose the “Advanced options for Peppermint” option and hit enter … now see if you can see Memtest86+
