Backlight on NF310 running Mandriva

Postby anthony » 26/12/2010, 15:13

Hello,

I purchased a NF310 to do software development on the road. So far I am very happy with it. As I am familiar with Mandriva I installed powerpack 2010.1 on the NF310. All is working fine (speakers, microphone, camera, wifi, lan, usb etc) except backlight control. I read on this site that you solved this problem for Ubuntu. Can you assis me to do it for Mandriva as well as this is my preferred distribution.

Some hardware info I retrieved:
from lspci:
00:00.0 Host bridge: Intel Corporation Pineview DMI Bridge (rev 02)
00:02.0 VGA compatible controller: Intel Corporation Pineview Integrated Graphics Controller (rev 02)
00:02.1 Display controller: Intel Corporation Pineview Integrated Graphics Controller (rev 02)

from lsmod:
uvcvideo 46543 0
videodev 30258 1 uvcvideo
v4l1_compat 10471 2 uvcvideo,videodev
i2c_core 16701 6 videodev,i2c_i801,i915,drm_kms_helper,drm,i2c_algo_bit
video 16395 1 i915
thermal_sys 11352 3 processor,video,thermal

usbcore 118015 6 btusb,uvcvideo,uhci_hcd,ehci_hcd,usbhid

from dmesg:

My /sys/class/backlight/ directory is empty.
I would be happy with a console command or tool to set the backlight level (or GUI or keys).

Thanks.
