Hi, In kernel prior to 3.7 I used to control the brightness through gnome-control-center (or writing a value in /sys/class/acpi_video0), but since 3.7 this is broken (ditto for the brightness function keys which are supported since this version), unless I boot with the '!Windows 2012' kernel parameter. I guess commit a57f7f9175b8 is the culprit, however I didn't try to boot with it reverted yet. Apart booting with the above kernel parameter, I guess it would be possible to blacklist the "video" module in order to make the backlight control fallback to intel_backlight. Anyway, I don't know if this issue is exclusively the kernel fault or if the firmware is at fault too. Also I didn't check if there was a possibility to add a quirk for this system to avoid it to boot with the Windows 2012 _OSI deleted. Thanks and have a nice day, Vincent - -- System Information: Debian Release: 7.0 APT prefers testing APT policy: (990, 'testing'), (500, 'testing-updates'), (500, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 3.8-trunk-amd64 (SMP w/4 CPU cores) Locale: LANG=fr_FR.utf8, LC_CTYPE=fr_FR.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iEYEARECAAYFAlEzka0ACgkQbO4uEp7kOBM8bACg1LF9IWl6t5hbsiHnp1bWCZn7 xr0An3uDV5RJtBP+2/gjHqM58UBfMOYe =eAH1 -----END PGP SIGNATURE----- -- To UNSUBSCRIBE, email to debian-kernel-requ...@lists.debian.org with a subject of "unsubscribe".
