Brightness keys Thinkpad T410

[yaslam]

Hi, I have a Thinkpad T410 and the brightness keys do not work in MATE desktop, how do I make them work?
Thanks

Do you have the appropriate module loaded?

Try in a terminal as root

kldload acpi_ibm

If that doesn't work try

kldload acpi_video

And see if that helps

Ah sorry for not replying, this did not work.

The brightness keys don't work but doing "sysctl dev.api_ibm.0.lcd_brightness=0" or any other number works.

This worked . I used the information at https://man.freebsd.org/cgi/man.cgi?que ... ease-ports in the EXAMPLES section to make the brightness keys work.
And now it works perfectly!
