Emulationstation on touchscreen + HDMI problem

[ArgonalDunlop]

Hi,

just can't found any solution to this issue. I have touch screen attached my rasp and now I want play with external monitor via hdmi.

I have set G3 GL Full KMS OpenGl driver in raspi-config:

dtoverlay=vc4-kms-v3d
start_x=0
gpu_mem=128
hdmi_force_hotplug=1

When I try to start emulationstation from terminal, system says:

failed to add service - already in use?

I had working this setup earlier but now it seems to be broke. Any ideas?

The correct line is dtoverlay=vc4-fkms-v3d.

When I modified that line, screen is seen only touch screen and in monitor it shows that startup rainbow screen.

Is there any other places to enable/disable HDMI output? Is there any way to disable touch screen via script?

Post your config.txt and the info asked in https://retropie.org.uk/forum/topic/3/read-this-first.
