Help needed: ThinkPad T480 Fn keys not working properly on FreeBSD 15 (XFCE)
-
Hello There ,
I’m running FreeBSD 15.0 on a ThinkPad T480 with XFCE and LightDM. Most things are working fine (i915kms, WiFi, etc.), but I’m having issues with Fn keys.- Brightness keys are detected but don’t change brightness (only works via
xrandr) - Volume keys are detected but require manual
mixercommands - Keyboard backlight key is detected but no action occurs
What is the recommended approach for full Fn key support on ThinkPad systems under FreeBSD with XFCE? Is native backlight control supported, or is xrandr the practical fallback? Should this be implemented via XFCE bindings, devd, or custom scripts?
Thank you

Iirc acpi_ibm loaded in rc.conf or loader.conf is needed for those "special" keys to workanybody feel free to correct me. I am on my OpenBSD box, I can't check myself here, atm.
/e: as follow-up: @evgandr@mastodon.bsd.cafe recently made this blogpost on Thinkpad specific keys too.
hope it helps and as always ymmv
