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

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

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

Macbook 5,1 with MCP79 lost its backlight control since the recent change for supporting GFP-RM; it rewrote the whole nv50 backlight control code and each display engine is supposed to have an entry for IOR bl callback, but it didn't cover mcp77. This patch adds the missing bl entry initialization for mcp77 display engine to recover the backlight control. Fixes: 2274ce7e3681

Hi there, A lot of people are experiencing problems with backlight support. It seems that they won't be any solution in near future, so I wanted to ask if nouveau is going to support the backlight management, and when ? thx sebastien

I do not use my laptop often, normally my better half has possession and use of it. It is a late 2011 ASUS ROG G73S which performs very well. The keyboard backlight was an issue initially under CentOS6, but the kind folks at elrepo found the missing bits in a more recent kernel and created a package to add them to the older CentOS6 kernel. An upgrade to CentOS7 went without a hitch and the

Hi, I wrote a patch for nouveau_backlight.c to support the backlight control of the GT 525M. Only the case NV_C0: is needed to get the backlight control with my NVC0 card working. I don't think that it's worth to add new functions for c0 if the old ones still work. This is my first patch for the Linux kernel.

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 all, I have found one problem after upgrading to CentOS 5.2 x86 on my HP Compaq nx7010 laptop. When I close and open lid, backlight is not turned on again. I can see my desktop, but the only thing I can do is press CTRL+ALT+BACKSPACE to restart X11. Then the backlight is restored. xorg.conf is generic, created by installation process. I use ATI proprietary driver 8.28.08 (the last which

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.
