Hi, I share the answer I have received on Reddit:

"Setting brightness through acpi\_ibm sysctl no longer works for me on FreeBSD 14 as well, but there's now a system program named \`backlight\` (not to be confused with \`xbacklight\`). It took me some time to find it since my backlight setup stopped working after updating 13 -> 14. Try using it to set brightness instead."

It works fine this way. I think that it should be documented in acpi_ibm man page.

Regards.
