I also recently updated a desktop FE computer to Ubuntu 24.04 and MythTV 
v34 -- fresh install (had the 24.04 installation wipe the original 
22.04).  Quite frankly nothing but problems and I think all due to 24.04 
and the hardware combination: AMD FX-8300, main issue seemed to be the 
graphics card using an NVIDIA GT218 [GeForce 210].  That GPU is not 
supported since 23.x and for me caused all sorts of semi-random lockups: 
MythTV (v34) always worked fine but going to Ubuntu's Settings, Files, 
and the like: screeching halt!  :(  I did try various corrections I 
found -- wayland to X11, an Nvidia patch, etc. -- nothing worked and 
some made worse.

OTOH my Backend is Ubuntu 24.04 and runs fine.  It has an Intel 
i7-12700K, so integrated graphics (which I found from a different system 
is a problem if want more than two monitors attached).

So I'm thinking perhaps your hardware combination is causing problems.  
As I said, I took that Frontend back to Ubuntu 22.04 and the problems 
magically went away.


As for your FE crashing some time after the TV is off/disconnected from 
the Frontend's video card.  That might be due to MythTV loosing the TV's 
EDID information.  (Wonder if happens after midnight?)  Monkeypet and I 
had a thread a while back which may help lead you to a solution -- for 
Raspberry Pi but might be modified.  Thread is at  mythtv-users Digest, 
Vol 262, Issue 17: Message: 8   Date: Mon, 13 Jan 2025.


I also had a note re: checking the CEC settings:  Setup > General > 
Remote Control.


Hope some of this leads you on the path to fixing your issue -- and let 
us know!
