Fn buttons to change brightness do not work?

I cannot change my brightness settings when in XFCE. When I am in a tty (ctrl+alt+f2) I can change the brightness with the keys, and then go back to XFCE, and the brightness will be at the level I set it. I cannot change it once back in XFCE though. I can also edit /sys/class/backlight/acpi_video0/brightness, and the brightness will change in the tty, but not in XFCE. Does anyone know how I can fix this?


If it matters, I'm running Archlinux and the output of lspci | grep VGA on my machine is:

01:00.0 VGA compatible controller: nVidia Corporation Device 1057 (rev a1)

Thanks for any help!

Re: Fn buttons to change brightness do not work?

Since you've got an nvidia card, another thing you can try is to add:

Option "RegistryDwords" "EnableBrightnessControl=1"

...to the DEVICE section of your /etc/X11/xorg.conf file. I believe you need to be using the proprietary driver for this option to work.

No. All symptoms are still occuring.

I'm using the proprietary drivers (Nouveau didn't work), but I don't have an xorg.conf file. I have an xorg.conf.d directory, but that only shows the following:

[eric@blackmesa X11]$ pwd
/etc/X11
[eric@blackmesa X11]$ ls
twm  xinit  xorg.conf.d
[eric@blackmesa X11]$ cd xorg.conf.d/
[eric@blackmesa xorg.conf.d]$ ls
10-evdev.conf   10-synaptics.conf            50-twofingerscroll.conf
10-quirks.conf  50-thinkpad-trackpoint.conf
[eric@blackmesa xorg.conf.d]$

Do I need to create an xorg.conf file? If I do, can someone point me in the direction to a guide on creating one?

Thanks again for the help!

Re: Fn buttons to change brightness do not work?

Try creating an /etc/X11/xorg.conf.d/20-nvidia.conf file with the following contents:

Section "Device"
    Identifier     "Device0"
    Option "RegistryDwords" "EnableBrightnessControl=1"
EndSection

If that doesn't work, post back your Xorg.0.log file without this file present.

Re: Fn buttons to change brightness do not work?

How about this:

Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    Option "RegistryDwords" "EnableBrightnessControl=1"
EndSection

Post back the results of the Xorg.0.log file while using this config file.

Also, what is the make/model of your computer?

Re: Fn buttons to change brightness do not work?

How about this:

Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    Option "RegistryDwords" "EnableBrightnessControl=1"
EndSection

Post back the results of the Xorg.0.log file while using this config file.

Also, what is the make/model of your computer?

Okay, I was able to fix the physical control of my brightness.

I found that I'm using the nvidia 290.10-1 driver, and I found that I could add the following kernel options:

acpi_backlight=vendor acpi_osi=Linux

Now I can change the brightness in xfce. The only problem is the image that shows the brighness level (pops up in the middle of the screen) does not change; and it only appears when I turn the brightness up. Is this fixable, or can I just disable the image from showing up all together? Thanks!
