I have an arcade terminal (JAMMA) with a CRT HANTAREX 9100 at 15hz mounted with a JPAC with jumpers at 15-33hz that prevent to send high freq to the CRT. I’ve mounted PC to JPAC through VGA cable

I’ve build batocera v35 working and accessing via WIFI/Putty from another computer

I’ve been following https://wiki.batocera.org/batocera-and-crt

first run ls/sys/class/drm

card0 card0-DP-2 car0-HDMI-A-2 renderD128

card0-DP-1 card0-HDMI-A-1 card0-VGA-1 version

1st syslinux.cfg

I’ve found this archive in different places so I changed all of them

/boot/boot/syslinux/syslinux.cfg

/boot/boot/syslinux.cfg

changing

APPEND label=BATOCERA console=tty3 quiet loglevel=0 vt.global_cursor_default=0 mitigations=off

APPEND label=BATOCERA console=tty3 quiet loglevel=0 vt.global_cursor_default=0 mitigations=off video=VGA-1:640×480ieS

Then I run

xrandr -display :0.0 | grep “connect”

VGA1 connected primary 1280×1024+0+0

HDMI-1 disconnected

DP-1 disconnected

HDMI-2 disconnected

DP-2 disconnected

Afterwards, I’ve made the 10-monitor.conf file at /etc/x11/xorg.conf.d/ as follows

Section “Monitor”

Identifier "card0-DP-1"

Option "Ignore" "true"

EndSection

Section “Monitor”

Identifier "DP-1"

Option "Ignore" "true"

EndSection

Section “Monitor”

Identifier "card0-DP-2"

Option "Ignore" "true"

EndSection

Section “Monitor”

Identifier "DP-2"

Option "Ignore" "true"

EndSection

Section “Monitor”

Identifier "card0-HDMI-A-1"

Option "Ignore" "true"

EndSection

Section “Monitor”

Identifier "HDMI-1"

Option "Ignore" "true"

EndSection

Section “Monitor”

Identifier "card0-HDMI-A-2"

Option "Ignore" "true"

EndSection

Section “Monitor”

Identifier "HDMI-2"

Option "Ignore" "true"

EndSection

I run at his point as the wiki says batocera-save-overlay

but when I run xrandr -display :0.0 | grep “connected” I got the same result as at the beggining!

What I did wrong?!

EDIT: It is FIXED. I don’t know why but it is working properly. Perhaps I did not reboot properly
