Hi Folks,
Longtime Fedora user here. Last winter, I got a Raspberry Pi, and
installed F28 on it. Using the HDMI output, it works well. Recently, I
picked up the Raspberry Pi 7" display (and case). After hooking up the
display to the Pi via the ribbon cable, I booted it up.
The 7" display works well as the initial console, and I see all the
usual messages go flying by. At some point (when it decides to switch
to graphics mode) the display goes blank. Nothing on it. I cannot
switch even to a virtual console. The new case blocks using the HDMI
port, so I had to remove the Pi from the case (while leaving the ribbon
cable attached to the display). After plugging a monitor into the HDMI
port, what I discovered was that the Pi boots using the display as
console, then switches to the HDMI port for the X11 driver. (not useful)
How can I get the X11 display to come up on the 7" display in graphics
mode. What do I need? A new xorg-x11-drv driver? A newer kernel?
I'd like to turn this into a MythTV server (with a USB capture) and use
the display as a system console with the ability to watch videos on it.
(Yeah, I'm aware that its only a 800x400 screen.) Failing that, I'd
like to use it in a "tablet" mode and get used to the touch screen
interface.
i do have a couple of suggestions and ideas that might be of help.
i'm a longtime user of mythtv and what i really like about it is its scheduler.
but there are other areas that could use with improving or using something else
for.
so one idea is to let tvheadend control your capture devices (for example usb
based) and then point mythtv backend at tvheadend.
to make this work i created a php script to produce a correctly formatted m3u
file based on data from tvheadend automatically that makes mythbackend happy.
basically mythbackend streams from tvheadend.
this kind of setup can give you a few additional things compared to a pure
mythtv setup.
main reason for me was the lack of dvb-t2 plp support in mythtv making most
channels not show up, plp is supported in tvheadend with a bit of fiddling with
settings.
also you can then use for example kodi as frontend and let kodi use tvheadend
as pvr and setup your media library (like recordings) to point to where
mythbackend stores it.
only thing your then missing is a way to schedule things in mythbackend but web
interface probably works.
i don't know if it is easier to setup kodi instead of trying to get x11 working
with your display.
one issue you will likely run into is that tvheadend at least the one in fedora
28 does not include the needed bits for support for a ca module.
this i had to rebuild myself and compile in.
the issue is the need for libdvben50221 that is part of dvb-apps but not
included by default in the package.
i haven't followed development of tvheadend closely in this area but i hope it
gets fixed properly and ca module support gets added to tvheadend in fedora.
oh, i almost forgot.
as you know the filenames created by mythtv is not very user friendly so i made
a script around mythlink.pl so it can tell the difference between movies and
series and then produce a folder structure more compatible with kodi and its
way of figuring out what metadata to load.
another way instead of this would be to point kodi at the upnp exposed library
by the backend, this is also a quite nice structure with sane titles and so on.
