Partitioning for Kubuntu

[logan01]

I will learn this, though, ya'll may suffer through the process. Thanks again everyone for all the help. Priceless.

This was it:

cd / && sudo find -name *grub*

There are always more clever ways of writing these things, too! I tend to be not-too-sophisticated, more straightforward, basic, "naive" ... easier to understand when you try to read it after some months pass!

People like to help. It keeps us on our toes, and you can always learn something new by helping out.

I keep a note pad nearby to write down new commands I come across. Then when I have time, I type them up and print out.

Commands is what that how-to you cited (yesterday) is all about:

https://www.kubuntuforums.net/showth...sole-Beginners

If you have questions, you can always post them here in the main forums (better than posting in the how-to section), like you are doing now, under New Guy or Misc. or catch-all, etc.

Duh. I even have that link on my Bookmarks bar.

Please forgive me, I can't resist:

richard@richard-HP-15-Notebook-PC:~$ swapon

Usage:
 swapon [options] [<spec>]

Options:
 -a, --all              enable all swaps from /etc/fstab
 -d, --discard          discard freed pages before they are reused
 -e, --ifexists         silently skip devices that do not exis
 -f, --fixpgsz          reinitialize the swap space if necessary
 -h, --help             display help and exit
 -p, --priority <prio>  specify the priority of the swap device.
 -s, --summary          display summary about used swap devices and exit
 -v, --verbose          verbose mode
 -V, --version          display version and exit

The <spec> parameter:
 -L <label>             LABEL of device to be used
 -U <uuid>              UUID of device to be used
 LABEL=<label>          LABEL of device to be used
 UUID=<uuid>            UUID of device to be used
 <device>               name of device to be used

Just had to do it.

and you can edit that text, too, adding red or bold-face, or introducing blank lines for readability between command blocks, etc.

Please not in the Code box of post #36 the Slab partition highlighted in red.

The only thing WE did was to make the swap partition a bit on the heavy side at 8 GB, unless you meet the criteria elijathegold posted or you end up needing it.

I wasn't paying much attention, wasn't concerned, didn't care ('cause we can care too much sometime), was following other rules you'll see (like 2 x RAM or 1.5 x RAM), and generally knew it was OK. Almost certainly, you probably will not need the full 8 GB, so we are on the safe side -- assuming you can afford the space, which it looked like you had plenty to spare. And so on.

In the future, I would hang on to and refer to these guidelines and rules of thumb:

It doesn't matter too much and better to err on the large side. I remember using the old 2x rule but that was back in the day when 1 and especially 2 GB was a good amount of ram which does make me feel old! Now-a-days everyone has an opinion on how much swap and those numbers I used are based on the majority views from many such discussions.

It doesn't mean they're right though. I mean the majority of UK voters thought a Tory government was a good thing

[Qqmike]

@elijathegold: Ha! You're right: on this subject hard to tell who's right, and what "right" means. Well, anyway, I thought your summary of the principles and rules of thumb were pretty good.
