Took a break from study to look at the "Button" issue plaguing 19's.

Did a little digging and I found:

cateee.net/lkddb/web-lkddb/PANASONIC_LAPTOP.html

talking about modules which lead me to search my computer.

I found Panasonic in:
/sys/class/backlight
/sys/devices/virtual/backlight
/usr/src/linux-headers ... /include/config
/sys/bus/acpi/drivers
/sys/modules
//etc/acpi/events

Do not get excited about acpi events, try this in a terminal:

you@yourcomputer:~$ acpi_listen

It will show the events as keys are pressed, notice that the
light keys get listed, the keys we want to work, don't.

So then I found this:

https://github.com/heiher/panasonic-hbtn

Downloaded zip, ran make, no love.

But its a clue in the quest to make these darn buttons work.
I will document any findings here, feel free to help with clues or a solution.

So you must have W7 installed ??

What about that extra stuff I found for Emporer? It's tailored for Linux on Toughbooks.

xrandr
I was never able to trace the electric impulse? from a button push...where does it go? Forget what Linux commands I tried.

Had a crazy idea about loading front button drivers in .wine, never tried it.

Are the buttons not simply on/off? We need to hack the rotation driver in W$ and see what it's doing in English.

you guys are very funny....now that i might have more time on my hands, and I have a CF-19 at my fingertips....let's dig in....this where you lead me??

Sorry I fell off the grid, stuff got crazy.

From what I can tell, when you push the button an event does happen, but not in acpi, it is going to the kernel. The stuff I downloaded from github didn't work as advertised and in fact messed with my power settings. I cannot completely log off, it goes into some sort of weird sleep mode. Of course I was pushing lots of (software) buttons and messing with lots of stuff in the background, its not the first time I have nuked a perfectly good install.

I am caught up as of today and will start looking at it again.

Oh and its not just a button on off thing, most things inside a computer are like signals,

"button pressed", (micro seconds later) "button released" -- events.

Its not simply a momentary button, (physically it is) but how the system reads it. It goes to a buffer and then is picked up by the OS to respond to the users desires.

I am getting deja vu. I think we already went through this somehow, or found another site with a custom module somewhere.

Many have tried.

I don't hear anyone bragging about success.

Glitch is young.....it's not the correct answer/ it's the quest that makes it fun.

Carry on.

it's no problem to get it to work. just compile and than use "sudo insmod ...ko" to activate/test.

i got it to work with opensuse leap, but i don't know how to map the virtual keyboard i use or an rotate-script
