<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>
