LightDM - Apr 2016 - question about lightdm when screen is offline

Hello,


I have a special project on Odroid with Ubuntu 14.04lts and lightdm.


Some times, the LED screen is off when booting the ODROID so when lightdm is
starting, the resolution is 720p and only a cursor on a black screen is
displayed (when we turn the screen on again)


I would like to force lightdm to start normally on 1080p even if the screen is
off. What should I do? I have tryed forcing resolution in both xorg.conf and
boot.scr but nothing does the trick.


When the screen is on no problem but when the screen is off, I can't boot
lightdm normally.


Can someone help me?

Nadir Merouane.

Hi Nadir,

LightDM doesn't control the screen resolution, so you should look at the
greeter or session you are running to check if they are handling the screen
resolution correctly.
