<p>Thanks again Ted,</p>
<p>I looked for /boot/efi and there is a directory with many files.
Below is how I got there. In the screenshot you can see Swap is
using very little memory when I use my machine normally. The
second screenshot shows the directory /etc/boot on the disk
/de/sda1 and the linux file system on /dev/sda2. gparted has only
two partitions (see below from gparted). So the question begs how
swap memory is an issue at all? Here's the output of my digging
for swap and not finding it in the directory as shown below,
/etc/boot. I also found an ubuntu directory and listed the files.
Again other than grub the results are Greek to me! <font

<p>I am loathe to increase the swap memory when it doesn't appear to
be a problem according to System Monitor. Anyway, here are my

Again, many thanks.</p>
<p>Brian</p>
<p>PS: this is not a serious issue as I can do a hard shutdown and
boot up again. Next time I'm hopefully going to be doing nothing
important and I can just walk away and see if the machine
un-freezes. I'll let you know if I go that route and the results.<br>

<div class="gmail_default" style="font-size:large">Brian, Right,
looks like you did a fresh install of 20.04 and the default in
Ubuntu is now a swap file, not a partition. So... you could
give a try at the method of increasing swap as described in
your first email in this thread. the series of commands
basically disconnects swap, then you blank some desire amount
of free space, then designate this as the swap directory and
enable it. Let us know how it works out. Thank you, Ted P.<br>

<p>One observation that just came to me is the issue again
copied below is relating to increasing swap is as a
partition in 20.04 but as you can see I do not have a swap
partition but I have a 2GB something...file? Also a couple
of screenshots from system monitor. It seems that swap has
plenty of memory, at least as I run four applications open
and hidden process. Maybe they are of some help?</p>
