Re: VPCZ11 backlight control

 

My BIOS Version is R2070C3. Has anyone tried with this BIOS version yet?

I still get panic for intel GPU. I've tried 2.6.33-rc1, but still I
get a panic after screen flickers and turns black when xorg starts.

Has anyone done that, and if yes, what's your bios version?

You can use "enabling advanced bios menu" trick to be able to use nvidia
GPU.
It's a bit risky but works.

I am using the Intel GPU and I can control the Backlight.
I am using Kernel 2.6.35-rc1.
rc2 won't even load.
rc3 just shows a bootscreen.

Everything is working except my nVidia Card and standby.

I've tried many methods to make nvidia backlight working(acpi video
module on 2.6.34 and 2.6.35rc[2,3], nvidia_bl module with added GT330M
id) but none of them works for me. I'm stuck with using
nvidia-settings color correction.
Intel GPU still panics on every kernel I tried.

(running 2.6.35 kernel)
(this doesn't work for the monitor on VGA, haven't tried with hdmi)
