Peter, to confirm that, could you tell me whether you have ACPI_VIDEO (a kernel config option) disabled? I'm hoping for a kernel configuration of: # CONFIG_ACPI_VIDEO is not set With ACPI_VIDEO disabled (a default on quite a lot of systems, as it depends on video output switching) SBLL did indeed fail to update the display brightness. Also, the display hotkeys failed to work. Events were reported, but the "before" and "after" levels were always the same value. After loading ACPI_VIDEO, the hotkeys came to life. Also, after looking at the DSDT I decided to specifically disable use_alt, causing the driver to use SBLL & GBLL instead of SBL2 & GBLS. Display brightness continued to be controllable. (And the Fujitsu laptop driver continues to be useful, as backlight control methods are not present on the ACPI video device) So it seems to me that we should: 1) explicitly depend on ACPI_VIDEO through Kconfig 2) remove the use_alt framework Regards, Tony V. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAklf7VoACgkQp5vW4rUFj5qXigCfSsDP38ochJ7i6X3/eFiZ3SP1 UqEAn28yGSYRBLmvWA3+vNhDSJ1ro5oS =u1wO -----END PGP SIGNATURE----- -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
