@Zing [moderated] working fine.

I edit this file .xinitrc and enter this line
xrandr --output eDP1 --off
Now ES MENU IS ON FULL SCREEN BUT GAME IS NOT WORKING.

@Zing i run this command.
DISPLAY=:0 xrandr --listmonitors
Here is the output.
Monitors: 2
0: +eDP1 1366/310x768/170+0+0 eDP1
1: +HDMI1 1920/1600x1080/900+0+0 HDMI1

@Zing Yes i have read but no luck

I have checked on other laptop same error coming.
Cant open display
Please helppp.

@Zing same error can't open display

I think it can be display driver issue because i had read some logs mentioned this.

HDMI1 mode not available.

@gnubit tried but same

Atleat i figure out to run kodi in full screen see screenshot.

I had also tried after kill emulation by pressing F4.

@Zing same issue through direct access
So what you suggest should i check other laptop.
