Too bright display in installer -- too much backlight?
I wanted to try installing ML on my laptop. I'm able to successfully boot to the installer, but there's one problem. Once the installer starts, it sets display backlight too bright. I'm almost sure this is the case, because when I choose "Shutdown" from within the installer, it switches for a second to text-mode background (booting with "-v" flag) where previously black background is now almost light-gray.
This notebook has two GPUs: Intel HD 3000 and NVIDIA GT 525M (the latter is disabled in boot cd's options).
To make Intel's HD 3000 work I had to modify stock DSDT using this guide: tonymacx86 Forum • View topic - Solved Blank Screen after Transcript Offline on IntelHD3000 .
I've also tried adding:
... to _SB scope right after PWRB, but the display is still too bright.
Name (_HID, EisaId ("APP0002"))
Name (_CID, "backlight")
Name (_UID, 0x0A)
Name (_STA, 0x0B)
What might cause this?
