Solve the NUC, batocare boot problem causes black screen

lyon00

The following is mainly for some NUC hosts, because the batocera boot causes the card screen and black screen to enter the system.

Download the refind installation package and extract it (download URL: https://sourceforge.net/projects/refind/)
EFI\BOOT will delete the bootx64.efi and grub.cfg in the original folder, and after decompressing, the contents of the reduce folder will be copied to EFI\BOOT and the original folder will be deleted.
Rename refind_x64.efi to bootx64.efi
Copy a separate copy of refind.conf-sample to refind.conf, and edit it to

Menuentry "batocera.linux" {

Volume "batocera.linux"

Loader \boot\linux

Initrd \boot\initrd.gz

Options "label=BATOCERA console=tty3 quiet loglevel=0 vt.global_cursor_default=0"

}

After saving, copy to EFI\BOOT and copy the copy to the grud folder in the boot of the system disk to delete the grub.cfg in the original folder.
There is also a grud folder that needs to be renamed to refind.
In this way, some NUC machines can solve the problem of booting black screen (which has been tested in Acte Angle PC). The tablet has not been tested, and theoretically it should be feasible.

Yes, but this problem was solved longer time ago (11/2018), as I was having it on my Beelink X55. 🙂
And exists also on Odroid H2. I posted on a few places in the forum my link : http://zclub.eu/efi.zip
Just to replace both files in the \efi\boot folder.

Dragu Directly replace the two files in the \efi\boot folder. Do not modify other files? Can a tablet be used as well?

Dragu lyon00 hi both of you. I face a black screen issue after batocera blue logo on AMD x64.
However, in my case, it is very rare I face this issue, and most of the time, everything happens well.
I suspect a "bad quit" issue (something like a voltage issue during shutdown in my arcade bartop).

To be sure, I just would like you to confirm if your issues are (were for Dragu) random or always the same ?

Thank you !

You need just to replace both files in the efi/boot folder. Anyway it is also based on refind.

It is not random but appears with some rare new bios. The effect is a black screen with just a white
mouse cursor somewhere on the screen.
Unfortunately it will not resolve all black screen issues.

Dragu Have you tested on the tablet, as far as I know, many tablets are also unable to enter the system.

Dragu So this is not exactly my issue. Mine is when I soft reboot, I have a black screen after batocera blue logo. Then I have no other choice than hard-shutdown (long press to Power button), and during this hard-quit, just before shutdown, I can see the batocera blue logo for less than a second (meaning that batocera was in the background, but on hold). Then, I have to unplug the power cable/plug again, and it come back to normal. This is why I suspect in my case many pôssibilities.
In any case, I have opened a topic related to my issue in order to not spam this one. Again, thank you both for your information !

No I didnt tested on tablets. I think even, it is a question of bios, not tablet, desktop, NUC and so on.
It is how the communication between bios and the cpu is executed and till now just very new processors
as the j5050, j41... suffers from this.

The black screen as you describe can be (just one possibility) that your PC enter for one reason or another the sleep modus. What also result in black screen. So, if you dont have working wakeup event, he dont come out . I was having on one PC something like this. Look perhaps one time if the sleep-modus is disabled in bios.
