The random reboots should be fixed with latest -devel kernel.

Also, unicsy-demo is packaged now. Version 0.5.2 -- please let me know
if it's working for you.

Also, ... I've packaged a droid4 keyboard layout, and also support for
the virtual keyboard special keys. You can see kind of what the third
level layout is, here:


If you dare, 'apt install leste-config-droid4' and 'apt upgrade' should
get you there. (on -devel) Might need to reboot to get it all applied.

Then 'OK' + 'shift' (control key, really) should get you the special
keys in the terminal. And 'OK' + a key with a third level should type
that key. So 'OK' + '.' = ':' now. With shift it's currently '>'.

xkb-data changes are here:

There's also a newer ofono in there with Tony's change for sim detection.

Now trying to get the data plugin in decent enough shape so that it too
can be in -devel. Then alsa UCM file for droid4.

Do you have patches for this, btw?
