similar to: Put acpi/backlight code into kernel

Several nvidia-based systems don't support backlight control via the standard ACPI control mechanisms. Instead, it's necessary for the driver to modify the backlight control registers directly. This patch adds support for determining whether the registers appear to be in use, and if so registers a kernel backlight device to control them. The backlight can then be controlled via

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

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

Steven, I found where the difference is, it may be my fault: My changeset number + 1 = your changeset number. My 11160 is your 11159, and my 11161 is your 11160.
