[Bug 762670] Re: Laptop brightness on Dell XPS not controllable
Dear Sirs! I am completely newbie in Linux and in Linux Mint in particular. In my case adding Option "RegistryDwords" "EnableBrightnessControl=1" clause in xorg.conf did not change anything in brightness. uname -a Linux Dell-XPS-L702X 4.10.0-38-generic #42~16.04.1-Ubuntu SMP Tue Oct 10 16:32:20 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux Xorg.conf # nvidia-settings: X configuration file generated by nvidia-settings # nvidia-settings: version 387.22 (buildd@lgw01-amd64-017) Tue Oct 31 00:34:18 UTC 2017 Section "ServerLayout" Identifier "Layout0" Screen 0 "Screen0" 0 0 InputDevice"Keyboard0" "CoreKeyboard" InputDevice"Mouse0" "CorePointer" Option "Xinerama" "0" EndSection Section "Files" EndSection Section "Module" Load "dbe" Load "extmod" Load "type1" Load "freetype" Load "glx" EndSection Section "InputDevice" # generated from default Identifier "Mouse0" Driver "mouse" Option "Protocol" "auto" Option "Device" "/dev/psaux" Option "Emulate3Buttons" "no" Option "ZAxisMapping" "4 5" EndSection Section "InputDevice" # generated from default Identifier "Keyboard0" Driver "kbd" EndSection Section "Monitor" # HorizSync source: edid, VertRefresh source: edid Identifier "Monitor0" VendorName "Unknown" ModelName "LGD" HorizSync 67.0 - 137.0 VertRefresh 60.0 - 119.0 Option "DPMS" EndSection Section "Device" Identifier "Device0" Driver "nvidia" VendorName "NVIDIA Corporation" BoardName "GeForce GT 555M" EndSection Section "Screen" Identifier "Screen0" Device "Device0" Monitor"Monitor0" DefaultDepth24 Option "Stereo" "0" Option "nvidiaXineramaInfoOrder" "DFP-2" Option "metamodes" "DP-1: 1920x1080_120 +0+0, DP-2: nvidia-auto-select +1920+0" Option "SLI" "Off" Option "MultiGPU" "Off" Option "BaseMosaic" "off" Option "RegistryDwords" "EnableBrightnessControl=1" SubSection "Display" Depth 24 EndSubSection EndSection Please, be so kind, help me in solving that issue.

[Bug 762670] Re: Laptop brightness on Dell XPS not controllable
I have a DELL XPS L702X laptop with the nVidia GTX 555M 3GB RAM with the 120Hz 3D Screen. I use Ubuntu 12.10 32-bit with the Experimental NVIDIA binary Xorg driver from nvidia-experimental-310(proprietary). Thanks to all the comments, I got my Fn+F4/F5 brightness working aswell. Though I did not have an /etc/X11/xorg.conf file to put the settings in, I created it manually using sudo gedit /etc/X11/xorg.conf and added only this: Section Screen Identifier Default Screen Option RegistryDwords EnableBrightnessControl=1 EndSection and saved the file. I rebooted the system, and now the keys work. I hope the issue gets resolved at some point.

For the non-tecnically minded could someone please explain exactly what to type or do to: add the following to xorg.conf: Option RegistryDwords EnableBrightnessControl=1 I have no idea how to add this to the xorg.conf file. This bug is extremely irritating. When the laptop enters power saving mode and you wake it up from a blank screen the screen is extremely bright and almost unusable even though the screen was dim and had a good screen brightness before powersaving mode.

I can also confirm that the suggestion posted by Pierre Chifflier works. Though myself not being a computer geek I had problems implementing it.

I can confirm that this still happens on 12.04 LTS. Adding the line to xorg.conf as suggested by Pierre Chifflier makes it work correctly.

Hello Can you please run this in a terminal: killall gnome-power-manager gnome-power-manager --verbose 21 | tee ~/gpm.log This kills gnome-power-manager and re-executes it in verbose mode, saving the log file gpm.log to your home directory. Try to change the brightness then attach this file to the report. The most useful things in this log are usually the values that g-p-m thinks that things are.
