NSA3xx Button setup

Hi,

I found 2 ways to set up all buttons on my NSA310 (probably all NSA3xx). Since I did not found to much about it on the net, I decided to share it with you all.

1. Install https://github.com/wertarbyte/magmakeys. Works perfectly. Advantages:
- this is a perl script so you do not need to compile and I think that all needed libraries are present in the bodhi rootfs;
- contains ready to use debian start-up script
- it is able to distinguish key stoke obtained by pressing, holding and releasing of a button;
Disadvantages:
- you need to switch off the hal support (there is no HAL daemon in modern linux distributions) and give the input event file specifically (-d /dev/input/event0);
- you need to manually put all needed files in appropriate directories.

2. Through acpid. The problem with is that acpid allows only keys predefined in the sources (the input_layer.c file). Unfortunately, KEY_COPY and KEY_RESTART are absent till acpid-2.0.23 (which is the current version in debian jessie). So the are 2 ways.
- Exchange KEY_COPY and KEY_RESTART with something like KEY_SLEEP and KEY_SUSPEND in appropriate dts file (kirkwood-nsa3x0-common.dtsi in my case). Then you need to recompile.
- Update to acpid-2.0.25 or later. It already supports KEY_COPY and KEY_RESET.

In both cases, you need only one daemon for all buttons.

That perl script is a bit ancient, but sounds interesting (and better than acpid, anyway). Thanks for sharing.

Thanks for sharing pld!

There is a 3rd method, which I like the most: using the esekeyd. It's cleaner, and out of the box from Debian.

My NSA325 config for testing (the NSA310S has similar config).

cat /etc/esekeyd.conf

#POWER:/sbin/shutdown -h now
#RESTART:/sbin/shutdown -r now
POWER:/usr/bin/logger -s -i "POWER button pushed"
RESTART:/usr/bin/logger -s -i "RESTART button pushed"
COPY:/usr/bin/logger -s -i "COPY Button pushed"

ps -deaf | grep ese
