[Nouveau] [Bug 93896] New: Nvidia GeForce GTX 970M unsupported, no backlight control
https://bugs.freedesktop.org/show_bug.cgi?id=93896 Bug ID: 93896 Summary: Nvidia GeForce GTX 970M unsupported, no backlight control Product: Mesa Version: 11.0 Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/DRI/nouveau Assignee: nouveau at lists.freedesktop.org Reporter: jvoss at altsci.com QA Contact: nouveau at lists.freedesktop.org Created attachment 121344 --> https://bugs.freedesktop.org/attachment.cgi?id=121344&action=edit Video BIOS The driver cannot load the firmware nvidia/gm204/fecs_inst.bin. Xorg won't load the nouveau driver because Unknown chipset: NV124. The backlight does not work. The following commands have no affect on the brightness: echo 2 |sudo tee /sys/class/backlight/acpi_video0/brightness echo 10 |sudo tee /sys/class/backlight/acpi_video0/brightness Brightness works with the proprietary nvidia driver. If mmiotrace logs are beneficial, I will add them. -- You are receiving this mail because: You are the QA Contact for the bug.

https://bugs.freedesktop.org/show_bug.cgi?id=93896 --- Comment #4 from Javantea <jvoss at altsci.com> --- Many thanks, great work on the GL support. Backlight is still not supported as far as I can tell on kernel 4.6.2 and Mesa 11.2.2. -- You are receiving this mail because: You are the assignee for the bug.

https://bugs.freedesktop.org/show_bug.cgi?id=93896 --- Comment #5 from Pierre Moreau <pierre.morrow at free.fr> --- Try the following patch: https://lists.freedesktop.org/archives/nouveau/2016-May/025081.html. You should be able to change the brightness through `/sys/class/backlight/nv_backlight/brightness` with it. -- You are receiving this mail because: You are the assignee for the bug.

Thank you very much! Home users will want it to be connected to xbacklight so that the fn controls will increase and decrease the backlight intensity, but I am quite happy to run a script. -- You are receiving this mail because: You are the assignee for the bug.
