Default No backlight control with Sony Vaio & Geforce GT 230M in openSUSE 11.2

Hi.

I have problems getting the backlight on my Sony VAIO(VPCCW1S1E) to work with openSUSE 11.2 and any driver version, even tried with beta versions.

I get recognized acpi events, and see changes in the files residing under /sys/class/backlight/sony when using the FN buttons.

Have tried various third party software without any luck so far.

I have compiled a bug report for you to see and i would be glad if this would be an easy fix.

If there is anything else you might need from me do not hesitate to ask for it as I'm eager to get this to work.

Thanks

Marcus

Is there anyone that might shed a light on this, I'm going total bananas over this, think i need to start to use sunscreen with factor 100 if i want to sit in front of the laptop anytime soon.

It was a year before backlight controls worked for my laptop, so unfortunately it could be a while before you get real backlight support.

In the mean time, you might check out the script I wrote to simulate it via the nvidia-settings program that comes with the driver.

Look for my old posting here:
