One thing I have been unable to resolve - after an extended period of
non use (overnight) the screen will be blank and won't wake up in
response to keyboard or mouse. I can switch to a console with
Ctl-Alt-F1 which gets me a login prompt, but Ctrl-Alt-F7 just restores
the blank screen.
Loggiing on I see nothing in dmesg, Xorg.0.log or mythfrontend.log
that indicates any issues or that the screen has been turned off.
I installed xfce4-power-setting and used it to disable all screen
blanking and sleep modes.
lightdm is running and a "service restart lightdm" wakes the screen
i up. One oddity - there's always two lightdm processes.
I tried disabling console-blanking, acpmi and apm in kernel setting
but that had the weird effect of disabling my irc device and hdmi
sound.

Any thoughts?
thanks,
