Found one easy solution (a least on Ubuntu 20.04) to implement manually solution by changing grub configuration.

Edit /etc/default/grub
To the parameter GRUB_CMDLINE_LINUX_DEFAULT add "acpi_backlight=vendor"
The line should be GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor"

update grub sudo update-grub

reboot

Don't know how to implement this in ubuntu distribution. Is it possible to create specific grub config during the installation process ?
