Hi everyone!

I'm having an issue with Yosemite 10.10.2 main installation screen (language selector and onwards).
Specifically - screen is constantly blinking and it looks like brightness level is jumping back and forth from dark to a slightly brighter level very fast, and the overall brightness level is very low ( and I cannot change it myself either ).
I didn't dare to continue the installation as I have no idea whether it is going to be any better after it.

USB stick is prepared using the latest Unibeast (5.1.0; laptop support included; NOT legacy USB).

Tried different boot flags: -v, -x, GraphicsEnabler=(Yes/No) and many more.
Basically followed this tutorial over here: https://www.youtube.com/watch?v=quky-WIFZG8

Any ideas why this could be happening? BIOS? :banghead:
Thanks in advance!

Please provide complete details in your profile/signature
(Profile/Settings link in upper right corner of this site)

System: manufacturer/model + bootloader(Clover/Chameleon/Chimera)
CPU: detailed CPU model + motherboard chipset
Graphics: all graphics devices + laptop internal screen resolution

For example, typical Ivy laptop:
System: HP ProBook 4540s (Clover)
CPU: i5-3320m/HM76
Graphics: HD4000, 1366x768

Use CPU-Z on Windows to find CPU (Core iX-xxx) and motherboard chipset (HMxx), and graphics capabilities. For a laptop, these details are important and affect critical installation procedures.

Is your internal panel connected via LVDS or eDP? Check in the Intel Graphics properties app under Windows.

I'm using Ubuntu instead of Windows. How would I get this info here?

It is probably there somewhere, but I'm no Linux expert.

You need to find out though... OS X has no support for eDP (until Haswell) and it common with Samsung laptops.

Like I said... no idea. I don't know Linux that well.

I'm a novice there as well - installed for educational purposes.:D

But, if we assume that it is in fact "LVDS" - what is the next thing to check?
And even if it was eDP - would that actually mean that there is no way to make it work with OSX? Or some "patching" involved?

There is a bunch of things to check:
- did you set the bootloader resolution to the native resolution
- which bootloader are you using?
- which bootloader flags?
- what are your BIOS settings?
- do you have UEFI?
- you could try injecting EDID
- you could try implementing brightness DSDT patches
- make sure you're injecting snb-platform-id (depends a lot on answers to questions above)

And even if it was eDP - would that actually mean that there is no way to make it work with OSX? Or some "patching" involved?

I don't know of anyone that has managed eDP for HD3000 or HD4000.

Samsungs are a PITA.
