I hope this doesn't confuse matters, but I'm running master on two 
rpm-based core2duo boxes, both around 10 years old.  The rpms are built 
locally and will differ from Richard's, but I'm not clear by how much.

All the mythtv components are run from tabs in a kde konsole.   No xmltv 
or services involved.

One box has an nVidia card, the other has just its original intel video 
system driving only a vga monitor.

On that box, mythtv-setup and mythfrontend will not have full graphics 
unless an environment variable has been set.  I use the command lines

$  MYTHTV_NO_EGL=1 mythtv-setup

and

$ MYTHTV_NO_EGL=1 mythfrontend

The box with the nVidia card doesn't need the preamble.

Maybe that will help.  Maybe not...
