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. </div> </body> </html>
