After boot often the screen became blak, sometimes I coul login but after
few seconds the screen turn blak, sometimes I could login again (pressing a
key on keyboard) but It doesn't last.
It work, but it wasn't stable, setting "nomodeset" before boot.

I hope It was useful.

Thanks. It sounds like perhaps the laptop lid switch or LCD backlight are misbehaving.

When the screen goes black, do you notice if:

* The machine is sleeping (power light has changed); or
* There is still a picture on screen you can see with a flashlight only.

Either way, please try the kernel parameter:

acpi_backlight=vendor

Yes I think the PC is sleeping, because often I can turn the screen on just
by pressing some key (not always, but the machine is on). Sometimes I can
see the cursor flashing.

I found a solution on Internet where they said "The problem was a
combination of a bug in the handling of closing/opening the laptop lid and
a kernel compatibility issue with the new 12th gen intel hardware"

and the solution (still working, but if I close the lid doesn't sleep!) is
on changing some settings in grub file and in logind.conf file.

from "GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

to "GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.enable_dc=0
intel_idle.max_cstate=2"

then add to the file /etc/systemd/logind.conf

the instructions:

  HandleLidSwitch=ignore
  HandleLidSwitchExternalPower=ignore
  HandleLidSwitchDocked=ignore
