Pi 4 Black Screen after autostart

yaya

Hi,

the relevant information:

Pi Model: Raspberry Pi 4 Model B Rev 1.1
Power Supply used: USB-C 4A Powersupply
RetroPie Version: 4.6 (image from Downloads)
Built From: retropie-buster-4.6-rpi4.img.gz
USB Devices connected: USB-Keyboard
Controller used: ?
Error messages received: which log to check?
Log found in /dev/shm/runcommand.log (if relevant): no such logfile

So my display is working properly, i can see video during boot.
once booting is finished, autostart of retropie is happening --> from this moment, I got a Black screen. Even touching the keyboard, there is nothing - no menu - no settings.

root@retropie:/home/pi# cat /boot/config.txt

disable_overscan=1

hdmi_force_hotplug=1
hdmi_group=1
hdmi_mode=16
hdmi_drive=2

dtparam=spi=on
dtparam=audio=on
dtoverlay=vc4-fkms-v3d
max_framebuffers=2
overscan_scale=1

EDIT:
If I am connected via ssh and run "emulationstation" - x11 is redirecting me the main menu, but windows is allways going to autohide. I cannot let the window in the front..

What kind of TV/Monitor do you have ? You've modified config.txt for 1080p, what happens if you don't ?

TV is a Samsung UE46F6500.
if I leave autoconfig, the result is the same.

I managed to put in values, because of this topic - without luck:

Which HDMI port are you using to connect the TV ? The one next to the USB-C power plug is recommended.

@mitu
haha no way - that was the solution!
may you should add this information into the FAQ ;-)

That's not a bad idea - we'll have a PI4 specific page 'really soon'. Have fun !
