This is implemented now in the source.

There is an additional fix in the source that addresses the large OSD
displays (e.g.mythcenter).

This only applies if using eglfs. I have not tried to get eglfs working
and I am concentrating on xcb. Since mythtv normally only works under X
this seemed the way to go.

Thanks for validating all of this and reporting back.

I will be creating a debian (deb) install archive next, so that it can
simply be installed with dpkg and then run without all of the manual
steps. Also that will support full deinstall.

If you want to build the source you will need to use a special configure
command on the raspberry pi. I am avoiding the LVR mythbuild.sh because
it is a monster and I don't know who will maintain it. It only supports
wheezy and jessie and does not support ubuntu, arch linux or others than
may now have a raspberry pi version.

For building on raspberry pi I have set up an external hard drive for
root and home partitions. Otherwise it takes too long and maybe will
wear out the SD card.

Regarding your setup tutorial, perhaps that should be in the mythtv wiki
(wiki.mythtv.org). You can sign up and create pages there as needed. We
can also add the page to the User Manual in the wiki.
