Nowadays a lot of rendering goes through 3d engine - as long as one has
capability, why not ? And it makes it easier to work with images, alpha,
etc.
Thus just because a program is 2d does not mean it does not use the 3d
graphics.
For example, one of the simplest way to make a movie player that is
capable of displaying multiple streams is to use opengl to paint frames on
2d faces. It could make a rotating cube, of course, but that is hard to
watch :)
How do I turn off the compositor? Do I need it?
Look in settings - this depends on whether you use KDE or unity or
something else.
The compositor is used for desktop effects like window zoom or making your
windows partially transparent.
Another suggestion is to try upgrading to 20.04.

There is some sort of bug in the version of KiCaD I have
(4.0.7+dfsg1-1ubuntu2) with its pcbnew program that puts my machine in a state
where I have to use the "magic" SysRq key to forceably reboot it (I can ssh in
from another computer, but /sbin/reboot does not work).
Judging by the messages it looks like a lockup in a video card.
Do other 3d programs run fine ? Try a 3d-game like quake or similar.
Try turning off the compositor. Also keep in eye on the fan and GPU
temperature.
It could be a bug in the driver, but nouveau worked quite well for me on
both 18.04 and 20.04 for many years.

I've included the last of the kernel log. It looks like something is broken
in nouveau, which I am guessing has something to do with the video somehow.
(And no, I am not going to download and install NVIDIA's video driver.)
I don't know if this is a kernel problem (I current have kernel
4.15.0-187-generic), or something in X Server.
