Comment (by Bradley Baetz <bbaetz@…>):

 I've attached a slightly different patch. This works against libcec2.1 (in
 ubuntu 14.04) as well as libcec1.6 (in ubuntu12.04)

 I wrote an initial version before seeing this, but then added in some of
 your changes.

 The main differences are:

  - applies cleanly, following my patch in #11986
  - removed the runtime version check - if the wrong libcec.so is present,
 we don't get that far (libcec has a very odd scheme, where at compile time
 all mythtv does is #include a bunch of wrappers around dlopen, avoiding
 the need to link to libcec at build time. Not sure why it does that...)
  - builds against libcec1.6 (the other patch uses some callbacks that are
 only available from v1.7)
  - I didn't include the change to explicitly setting a logical address -
 that method is documented as deprecated and only for debugging purposes.
 Instead, I left it for libcec to handle.
  - I kept the support for setting the parent device type from the patch,
 but not setting the physical address directly - the attached patch hard
 codes that to 2.2.0.0, so presumably only works for you? At least on my
 libcec version the search order is:
    - specified physical address
    - auto-detection in libcec of the port info from EDID (which only works
 on the ATI drivers and older kernels with older nvidia drivers that use
 /proc/acpi/video)
    - specified parent logical device/port combination (defaults to TV/port
 1)

 I kept the change you made to wake up the screen when the TV source goes
 active (although for libcec2 only; yours supports it from 1.7.1 but won't
 compile against older versions). However, it doesn't actually wake the
 screen up for me - I need a button press to do that like before. Is that
 part working for you? My screensaver/desktop might just be set up
 differently...
