My screen doesn't display anything after launch:/

Hello, here is the link of my video which shows my problem (For information, I use a raspberry pi 4B with the 4go of ram . I took the image GenPi64.img.xz) : https://youtu.be/WUTI_cP5S58

That looks like a boot loop, does it do that indefinitely, as in unless power is pulled? After it has reached the black screen, can you use SSH to login remotely and check logs or anything? You may need to use Ethernet for LAN access though for the RPi to get a IP address. If it does, I would recommend trying the lite image, and installing desktop environment by hand. (Gentoo and CLI knowledge required.)

It certainly looks as if it reboots at least once (although doesn't cycle after that). The culprit here is often the power supply - are you using an official RPi unit, or a phone charger or similar?

if you are using an official PSU, try editing the file /boot/config.txt (i.e., config.txt on the first partition on the microSD card; this is formatted FAT so you can edit it on any PC), and uncommenting the following line, so it now reads:

hdmi_safe=1

Save, leaving the rest of this file as-is, and try rebooting your RPi4B again (the above forces a very basic display; but if it works, you can then tweak further settings to increase the resolution etc.)

If that also fails to display anything, one other thing you can try is to edit the config.txt file again and uncomment and change the following line so it reads:

config_hdmi_boost=9

leaving the rest of the file as-is. This will produce a stronger output signal, which is necessary with some displays.

You can find more information about the video settings in (/boot/)config.txt here.

hth, sakaki

30 Oct 2020: sadly, due legal obligations arising from a recent change in my 'real world' job, I must announce I am standing down as maintainer of this project with immediate effect. For the meantime, I will leave the repo up (for historical interest, and since the images may be of use still in certain applications); however, there will be no further updates to the underlying binhost etc., nor will I be accepting / actioning further pull requests or bug reports from this point. Email requests for support will also have to be politely declined, so, please treat this as an effective EOL notice.

For further details, please see my post here.

Many thanks for your interest in this project!

With sincere apologies, sakaki ><
