I try:
-
Type export XAUTHORITY=
ls /var/run/gdm/auth-for-root-*/database
and hit enter.
Type export DISPLAY=:0.0 and hit enter.
Type xrandr --output HDMI-0 --mode 720x480 --rate 60. You can substitute different resolutions and refresh rates if you like. Hit enter.
and on uENV.txr -
video=HDMI-A-1:640x480@60
both didnt work.
I want to know if anyone manage to solve this problem without a hardware hacking.
Regards.
