[mythtv-users] FE won’t come out of sleep once every 24 hours

[Barry Martin]

Hi Folks!


I’ve been having an issue with one of my Frontends where some time in 
the middle of the afternoon it won’t come out of suspend (?) – black 
screen and need to REISUB to get going again. Sort of similar to Steve 
Greene’s thread earlier in this month (“AMD Ryzen freeze [OT]”) so I 
purchased and installed a new video card – no change.


Problem started maybe mid-September – why Steve’s post caught my interest.


‘Ton’ of what appear to be false-positives in the logs, for example:

  *

    W CoreContext screensaver-dbus.cpp:87 (Inhibit) ScreenSaverDBus:
    Failed to disable screensaver: Type of message, “(ss)”, does not
    match expected type “(susu)”

  *

    Entering standby mode after 90 minutes of inactivity


Googling those seemed to indicate not an issue, plus the logs on that 
Frontend show them, some going back to the beginning of May and I didn’t 
have the issue back then. Other problem is I don’t know what I’m looking 
for in the error message department. I haven’t seen anything that stands 
out.


Highpoints of the unit’s spec’s:

Ubuntu 22.04

MythTV v 31 (Fall project to update)

CPU = Intel Core2 Duo E7500 with 6 GB RAM (free shows no swap being used)

Video Card:

inxi -G --display

Graphics:

Device-1: NVIDIA GP108 [GeForce GT 1030] driver: nouveau v: kernel

Display: server: X.Org v: 1.21.1.4 driver: X: loaded: modesetting

unloaded: fbdev,vesa gpu: nouveau resolution: 1920x1080~60Hz

OpenGL: renderer: NV138 v: 4.3 Mesa 23.0.4-0ubuntu1~22.04.1


FE’s Setup > Video > Playback is set as ‘Normal’. I did try toggling 
this setting to something else, save & exit, then back to Normal, save & 
exit – sort of to re-configure. And yes, also played with Ubuntu’s 
Screensaver setting (it’s off). Obviously didn’t help.


So what else is needed to be know to fix my little problem?


Thanks!

Barry
