In Topic: HD3000 freezing in Sierra

Today, 08:00 AM

UPDATE: I've done a lot of experimenting and researching and here are my findings:


- Freezes are caused by a mismatch between the ports defined in the driver's frame buffer table and the physical ports in the laptop.

I fixed them by loading the second frame buffer table which limits the driver to 1 LVDS port. I don't use HDMI or VGA so I don't mind.

I think the same could be done by patching the first table to match BOTH port number and type. I prefer DSDT since it's cleaner.

Buffer (0x04)
0x00, 0x00, 0x02, 0x00    //load the 2nd frame buffer table (0x02)                   

- Artifacts are caused by IGPU memory corruption due a clover bug.

Clover somehow messes with the BIOS-reserved memory for IGPU.

apianti and Slice know about the issue and couldn't fix it (very long ago)


Slide=0 as boot-arg reduces the artifacts significantly.

Installing 8GB of RAM also seems to fix it. I haven't tried that.


Hope this helps :)

Slice, could you please update installer to 3975 on sourceforge?


Thanks in advance :)

is there any new version for v6 for two finger scrolling support. as v6 users we only need two finger scrolling. everything else is working. thanks a lot so far for the kexts. it really helped dr.hurt.


Did you ever have 2 finger scrolling with your V6 on mac? Or windows? The linux driver does't support multifinger for V6 which is why I though it wouldn't be worth the effort of porting it. You can get basic support using rehabman's generic ps2 driver.

I found out that the single most influential workaround for HD3000 artifacts is "slide=0" as a boot-arg.


Ever since updating to Sierra, I do get occasional freezes, for which I have yet to find a fix.

It seems to be related to memory pressure though. Using RAM intensive apps, I frequently get artifacts then system freezes after a few minutes.

I have a problem with SetIntelBacklight:


Brightness control slider, and Function Keys do NOT work. The brightness indicator shows up but brightness stays the same. Brightness values in nvram DO change and apply correctly on boot.


Not sure if this is actually fixable but thought I'd report it  :)
