< EDIT> Found it journalctl -f

I tried a few of the distros and all of them had the touchpad disable, even if it didn't say so.

Kubuntu
LinuxLite
BodHi

Yes BodHi.. so the BodHi Live Boot did recognize the fold and used that to disable to touchpad... but like all of them, that did not disable the actual keyboard

trying the same method of watching journalctl -f with one of these systems may provide some output.

another couple of thoughts after posting that: if your bodhi installation isn't addressing whatever that event or switch might be, it may not be enough just to find out what another system calls it. if you manage to catch the event in journalctl and figure out what the switch/hardware is called, sudo lshw (lspci or lsusb also might help depending on the setup) may help you get some additional information about how it is set up in that system.

prompted me to search for "acpi binding for convertible laptop lid". the first listing was this page using a similar system (-ish: thinkpad x230 with 16.04). the premise is about the same except that person wanted to disable the touchpad instead of the keyboard. there is a clear explanation about how to capture the lid flipping event and then convert that into an acpi binding as enigma9o7 suggested.

Yeah I wasn't very clear. Go into settings panel/input/acpi bindings, and click add. then move the laptop lid as desired, to see if it can see that action. If so, then you can assign it to a command that calls your script.

that definitely sounds like a much easier way to capture the event

unfortunately it dose not do anything. I click and and fold the screen but nothing seems to occur.

Something must happen, as when you normally do it, the trackpad turns off. So there must be some event getting triggered? The funny thing was when I had the "Add" thing open, the trackpad turned off when I folded it back but didn't turn back on when I folded it back. it usually dose so I assumed it was because of the "add" thing running.

as the acpi bindings tool didn't work, i wanted to add that i tried the suggestion on the page i mentioned here:

the first tool used (acpi_listen) doesn't seem to exist (at least it isn't on my system and i couldn't find a package for it) for ubuntu 18.04. installing acpitool does also install acpid which might help if you decide to try this route or something similar.
