Kinda regretting that :) heaps of issues that I eventually worked
though.
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,
i solved that with a conf file for xorg.conf.d; the 'connected monitor'
setting is the one
you need for that issue, i believe. mine looks like this:
Section "Device"
Identifier "Card0"
Driver "nvidia"
VendorName "NVIDIA Corporation"
Option "ConnectedMonitor" "DFP-2"
Option "UseEdidDpi" "False"
Option "DPI" "96 x 96"
Option "ModeValidation"
"AllowNonEdidModes,NoVesaModes,NoXServerModes"
EndSection
you have to look through your xorg log to see which device is
connecting and name that device
in the setting.
