initial ebuild

With a GNOME 3.18 (or newer) based system, orientation changes will automatically be applied when rotating the panel, ambient light will be used to change the screen brightness, and Geoclue will be able to read the compass data to show the direction in Maps.

gnome-base/gnome-settings-daemon needs the patches from:
https://bugzilla.gnome.org/show_bug.cgi?id=756539

otherwise, the log gets spamed with:

gdm: Error executing command as another user: Not authorized [USER=root] [TTY=unknown] [CWD=/var/lib/gdm] [COMMAND=/usr/libexec/gsd-backlight-helper --set-brightness 99]

This incident has been reported.

iio-sensor-proxy-2.0

This release adds build fixes, fixes the detection of a number of
devices that should be supported, stops trying to use devices
that shouldn't, and adds support for the "mount-matrix" property,
which can be used to fix the orientation of accelerometers on
devices where the default does not work.

    * Add support for ACCEL_MOUNT_MATRIX udev property
    * Fix startup failure on certain devices
    * Work-around possible kernel bug on certain devices
    * Better supported/unsupported sensors detection
    * Better debug output

this project has hard dependency on systemd, which is offered ebuild missing.

[Comment 5 Roman Zimmermann 2020-06-30 14:42:13 UTC]

It seems that the only reason for the systemd check in the build script is because a systemd unit file is shipped. For non-systemd systems we could pass any directory and then delete the file after the build. We’d still need to supply a OpenRC init-file though.

I got compiled iio-sensor-proxy without systemd using ebuild https://github.com/gentoo-mirror/guru/blob/master/gnome-extra/iio-sensor-proxy/iio-sensor-proxy-3.3.ebuild and the next patch:

/usr/libexec/iio-sensor-proxy needs an openrc wrapper (TODO), if started as root, the /usr/bin/monitor-sensor is able to read sensors.

~ cat /etc/init.d/iio-sensor-proxy
#!/sbin/openrc-run

command=/usr/libexec/iio-sensor-proxy
command_background=yes
pidfile=/run/iio-sensor-proxy.pid

depend() {
   need dbus localmount
}

That doesn't work for me, but funtoo's one does:

#!/sbin/openrc-run

depend() {
	need dbus localmount
}

start () {
	ebegin "Starting iio-sensor-proxy"
	start-stop-daemon --start --exec /usr/libexec/iio-sensor-proxy \
	    --background --pidfile /run/iio-sensor-proxy.pid --make-pidfile
	eend $?
}

stop () {
	ebegin "Stopping iio-sensor-proxy"
	start-stop-daemon --stop --exec /usr/libexec/iio-sensor-proxy \
	    --pidfile /run/iio-sensor-proxy.pid
	eend $?
}

I think that gnome-common is not need it. Here the ebuild I'm using:
