I am lost because Chris_OC tried the recommended grub kernel argument parameters to get his brightness working

I searched the web and found references to this problem with other versions of Linux revolving around editing the line GRUB_CMDLINE_LINUX_DEFAULT. I found two different edits, written as follows:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux"
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux acpi_backlight=vendor"

...and I tried both (separately, of course) but neither made any difference. Linux Lite tells me that brightness is at maximum, and changing it doesn't make the screen dimmer.

Sorry Chris. I am out of ideas on this one.
