Hi all, for everyone who has the same problem with setting the display brightness with the nvidia driver (in my case "390 legacy"), I found the following solution to "revive" the display brightness: In "/etc/default/grub" add "acpi_backlight=vendor" and/or "nvidia.NVreg_EnableBacklightHandler=1" to the variable GRUB_CMDLINE_LINUX_DEFAULT: GRUB_CMDLINE_LINUX_DEFAULT="quiet nvidia.NVreg_EnableBacklightHandler=1 acpi_backlight=vendor". ... and reboot. With this setting, controlling the display brightness using TDE and multimedia (or Fn combination) keys should work (works for me).
