To see if acpi_video(4) is loaded: enter 'kldstat | grep acpi_video' at shell prompt. If no output, acpi_video(4) is not loaded. To load acpi_video(4), as root enter 'kldload acpi_video' at shell prompt. If successful, try the brightness keys - maybe they'll work. You might provide me a dump of your ACPI tables to see if the _BQC method exists, on which (I believe) acpi_video(4) relies. To dump (and disassemble) ACPI tables to machine file 'perrin-dsdt.aml' and source file 'perrin-dsdt.asl', as root enter 'acpidump -t -d -o perrin-dsdt.aml > perrin-dsdt.asl' at shell prompt and send me either the .aml or the =2Easl file. > Experimentally, I edited some files and restarted the OS but there was > no improvement.

I don't think so, but I'm using the Radeon KMS driver. > _______________________________________________ > freebsd-x11@freebsd.org mailing list > https://lists.freebsd.org/mailman/listinfo/freebsd-x11 > To unsubscribe, send any mail to "freebsd-x11-unsubscribe@freebsd.org" --=20 Anthony Jenkins
