I think it could be a power saving problem or an issue with the screen flex cable

Gemini Lake is 6 years old, not "new". So, yes it could be the flex cable. Does behavior change if you disable GUI logo during POST in the BIOS? Is a BIOS update available?

The flickering stops when I move the screen (I'm not 100% sure about this) sometimes it stops randomly, otherwise it doesn't stop even if Linux already booted and after a couple of minutes the screen goes black.
Sometimes the flickering stops when loading linux, sometimes never stops but when it stops, it stops forever NEVER flickers again when I'm using the computer even if I move the screen the flickering never comes back once linux has booted and I can see the graphical interface. That's why I doubt it's a flex cable issue.

When I leave the computer turn off for a couple hours and try I turn it on the flickering is always back. So maybe a power issue, frequency issue or I need a BIOS update? I will check for BIOS updates later.

I thought maybe this was the problem:

I added to /etc/default/grub this line:

Code:

GRUB_CMDLINE_LINUX_DEFAULT="i915.enable_psr=0 i915.enable_fbc=0 intel_idle.max_cstate=0 idle=halt"

But I'm still having flickering issues

Sorry english is not my first language.

I just fixed the flickering issue by installing FreeBSD. After a couple of hours configuring my wifi with WiFiBox everything seems to work fine. If anyone wants to know I used this guide to configure my wifibox https://forums.ghostbsd.org/viewtopi...39a23c6436ce62
