I can see the text boot log, but then the screen blanks and stays lit
If I alt+f4 it switches back to a prompt but re-running emustation leaves a blank screen again
Not found any pointers yet, but was hoping I might find some ideas here
I saw a colour-gradient square when the pi turned on, but never saw any graphics at all (no boot splash screen, and no emulationstation graphics/ui), only the plain text console.
I also did not see the 4 raspberry graphics at the top of the console
Little bit more playing about and it seems to be working now:
I have the display plugged into hdmi port 0 (next to the USB-c port on the pi) and the upper USB 2 port for power
I’ve also used these settings in /boot/config.txt:
dtparam=audio=on
[pi4]
dtoverlay=vc4-fkms-v3d
max_framebuffers=2
[all]
overscan_scale=1
dtoverlay=picade
dtparam=audio=off
# Need this to actually turn the display on
hdmi_force_hotplug=1
# Need these to force display to 1024x768 (otherwise 640x480)
hdmi_drive=1
hdmi_group=2
hdmi_mode=16
Display status looks good now too:
# tvservice -s
state 0xa [HDMI CUSTOM RGB full 4:3], 1024x768 @ 60.00Hz, progressive
