Dell touchpads are usually pretty good.
I suggest to check which touchpad driver is being used, there might be
some useful messages in dmesg or /var/log/Xorg.0.log.
Another possibility is that the battery went bad, is buldging and pushing
on the touchpad.

You'll probably find logs in /var/log. Specifically /var/log/Xorg*
You might also find the output of
$ systemctl status display-manager helpful.

If you do teleconferencing, you might want to capture either the entire
screen, or some window.
If you want to record a movie of a game playing fullscreen, than you
probably need the position and dimensions of the game window, because
games often change video mode while keeping
intact.
If you want to make a better Xvnc, you probably need the code above and
you might not need xrandr.
If you are doing something else - who knows what you mean ?

And this what you get. Now when I say "Screen" I mean large rectangular
matrix of pixels I can paint on. Which is pretty much what any application
cares about - you don't need to paint outside of screen.
What do you mean by "Screen" and why ?
is xrandr. And don't forget to specify which of 5 screen you have running

Is Opengl mapped only into the server portion?

write non-critical data there, issue a barrier of some sort and then
trigger by writing to register in non-prefetchable space. This is pure
speculation, read noveau driver to find out.

en mapped by
the graphics driver. Some of those is real memory, some are registers and
are entirely virtual - there isn't any physical DRAM backing them.
These aren't all the regions exposed by video card, because if multiple
apps write to video card register directly it will lock up hard, freezing
PCIe bus. Instead, this is arbitrated by the kernel driver.

I will have to do some approximations using a combination of the processor and
IMC counters.

Will it avoid screen activation in the local machine?
There should be a rather drastic difference in speed between VLC

There is more than one console (usually), you can switch between them with
Alt-F1, Alt-F2, etc..
There are also ways to restrict profiling to a single process,
like "perf top -p 12345".

Try 20.04 or later - an install image on a USB stick should be enough to

Maybe the newer driver will fix it for you.

Another suggestion is to try upgrading to 20.04.

Try turning off the compositor. Also keep in eye on the fan and GPU
