Display brightness very low after recovery from suspend

My tablet Model is redmi notebook 15
CPU:i5 12450H
GPU:Intel UHD 730
system:Zorin OS 17 Core
All packages updated
relavant settings:
BIOS SECURE BOOT:OFF
Settings->Power:
Automatic brightness:OFF
DIM Screen:OFF
Screen Blank:5 minutes
Automatic Power Saver:OFF
Automatic Suspend:OFF

after I run "systemctl suspend" in terminal,it working,but when I wake up it,the display brightness too low,approaching to black screen,I just reboot my PC to solve it.

I searched any other posts like same,but didn't work.include add "nouveau.modeset=0" in grub config.

here is my kernel log after I wake up PC:

See if any of the solutions posted here help.

thanks for your reply,however the posts didn't solved the problem :smiling_face_with_tear:,this problem happens on both wayland and xorg,and display no respond after ctrl alt f1.

Could You try to turn that off and look if it works? Maybe do a Reboot after that.

I set "Never" and reboot,but didn't work :cry:

This sounds like a notebook computer backlight issue.

Since you have integrated Intel GPU, the Nouveau or Nvidia related fixes will not likely help you. But have you tried other Grub parameters like
pci=nomsi, or acpi_backlight=vendor remembering to run

sudo update-grub

after changing grub parameters?

I added pci=nomsi or acpi_backlight=vendor in GRUB_CMDLINE_LINUX="" of /etc/default/grub and then run sudo update-grub .but both of them didn't solve it.Maybe I should try whether this problem exists in other linux distributions.

Yes, that is not a bad Idea.
