similar to: [Bug 23023] no backlight support in /sys or /proc ; xbacklight not working

https://bugs.freedesktop.org/show_bug.cgi?id=23023 --- Comment #4 from Alex Mayorga Adame <alex_mayorga at yahoo.com> 2012-04-02 13:50:57 PDT --- Ended up here looking for a solution to "Fn+F5 and Fn+F6 don't modify brightness on Sony VAIO VPCCW (GT 230M)"[1] Posting the card details below in case they're useful to anyone. [1]

Xbacklight is used to adjust the backlight brightness where supported. It uses the RandR extension to find all outputs on the X server supporting backlight brightness control and changes them all in the same way.

That's great -- can you just confirm that this is what you did (every so often things work for the wrong reasons): (a) grabbed the ~darktama repo (b) took the MXM patch, futzed with the paths (since it was against the linux tree), applied it (c) took the patch off the mailing list, applied it (paths should have been fine) (d) DID NOT apply the vbios-pq1 patch in any form And then you built

Currently, every backlight interface created by Nouveau uses the same name, nv_backlight. This leads to a sysfs warning as it tries to create an already existing folder. This patch adds a incremented number to the name, but keeps the initial name as nv_backlight, to avoid possibly breaking userspace; the second interface will be named nv_backlight1, and so on. Bugzilla:

Hi, I'm trying to bring devs to support for backlight on nv50 cards for above 1 year, without any success A lot of laptop (from mac, hp, samsung) doesn't have laptop_panel in hal, and therefore no support for acpi/backlight..., and no entry in /proc/acpi/video nor /sys/class/backlight Kernel team is not reacting, hal team won't fix, devicekit need standardise i/o...
