What what action are you taking to make that happen?
Sorry, but you need to describe the issue fully.
Let me just start from the beginning -
1. My first problem was during install phase where the laptop display would turn black (no display) and i was not able to get to the installation step. You suggested to use an invalid ig-platform-id instead of 0a260006. The installation went through with this.
2. After the installation I changed the ig-platform-id back to 0a26006 and that caused same issue again. Laptop display turns black while the machine is still running nothing on the display. But I could get into the desktop with an invalid ig-platform-id.
3. You suggested BIOS video memory setting change + EDID injection. Both didn't help. Only difference with EDID injection was that instead of the laptop display going blank, the laptop restarts.
4. You suggested I probably need the Core display patch to defeat the pixel clock limitation for the internal display. As that is specific for high resolution display I connected the laptop with an external display(1920 x 1080) through HDMI to further troubleshoot the problem.
5. With the external monitor the the issue is similar as 2. The monitor goes to sleep mode, its power light keeps blinking with no display while the laptop is On. The laptop lid is kept closed the whole time. After this I am only testing with external display.
6. You suggested probably the HDMI port is connected to the discrete graphics and not the iGPU and to check that on windows.
7. I installed windows on another partition and found the display to be connected to iGPU and not the discrete graphics.
8. You suggested its a matter of missing connection. I searched and found related thread where you suggested two patches. I pulled latest config.plist from your repository for haswell and added those two patches in the config.plist. I tried boot again and the issue is still as 5.
I collected the Problem Files with F2 and F4 in the the case where the monitor goes to sleep mode and then I logged in using invalid ig-platform-id and collected the other set of problem files as required with my monitor connected. those have been attached.
Now, I could not verify if the display is actually connected to 0306 or some other connector. I don't know how do I check that.
