I might be wrong but it looked to me like samsung-backlight support not only netbooks but also
some notebooks. I have a R780 running Ubuntu Lucid (64 bits).
$ sudo dmidecode -s system-manufacturer
SAMSUNG ELECTRONICS CO., LTD.
$ sudo dmidecode -s system-product-name
The package samsung-tools works as it added support for the Fn keys.
I am getting trouble with the backlight.
The GPU on R780 is GeForce GT 330M (chip GT 216)
$ lspci |grep nVidia
01:00.0 VGA compatible controller: nVidia Corporation GT216 [GeForce GT 330M] (rev a2)
echo 6 > /sys/devices/virtual/backlight/samsung/brightness
has no effect. The Fn+Up/Down keys relate to gnome-power-manager with no effect on actual brightness either.
I had a look at the mactel ppa (https://launchpad.net/~mactel-support/+archive/ppa
) that provides the package nvidia-bl-dkms (I used version 0.16.10~lucid). With that I succeed to get control over brightess using the command
echo 1000 > /sys/devices/virtual/backlight/nvidia_backlight/brightness
Unfortunately, I could not link this to the Fn keys for control.
Here are my questions:
Does samsung-backlight work with some nVidia cards?
Do you have any suggestion?
Do you think support for R780 could be added to the project?
Thanks in advance.
