similar to: Keyboard backlight fails with recent kernels

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... I've

The nouveau code used to call drm_fb_helper_initial_config() from nouveau_fbcon_init() before calling drm_dev_register(). This would probe all connectors so that drm_connector->status could be used during backlight registration which runs from nouveau_connector_late_register(). After commit 4a16dd9d18a0 ("drm/nouveau/kms: switch to drm fbdev helpers") the fbdev emulation code, which

Hi Guys Sorry, I've been away for a few days. As the backlight is an iterative process I thought I'd get some feedback before I move to the next stage:- The colour of the backlight:- I think blue would work best? On/Off Status, I've put some thought into this and think the light should come on in the following circumstances:- Phone Rings Phone handset is picked up Speaker

Hi I've taken apart a 7960 to fit a backlight to the LCD. Would others on the list be interested in this as a project when I've finished (i.e. should I document and photo all the stages)? Also I can source some 7960's at a very good price but what are the rules about posting this information on the list if others were interested? P

Patches 1-5 are Reviewed-by: Karol Herbst <kherbst at redhat.com> I think it might be worth to test those patches on a system without any backlight devices just to verify we don't break things, but the code looked good already, so maybe we don't really need to test.

This series fixes some issues with nouveau's backlight support that were causing kernel panics on module reloads, specifically on systems with nouveau handling the backlight of one of the displays. While we're at it, let's cleanup nouveau_backlight.c as well Lyude Paul (5): drm/nouveau: Check backlight IDs are >= 0, not > 0 drm/nouveau: Move backlight device into
