  1. Hi I have a Lenovo X1 Carbon Gen2, i7-4600U Touch Screen 2560x1440 (WQHD), which I have spent about a week installing High Sierra. I tried to follow things the recommended way and got it all working, except that when I enabled framebuffer to get QE/CI, I keep getting the garbled distortions flashing all over the screen. I can see it is accelerated and is working but its impossible to use with the display that way. I tried all the various framebuffers for Laptops and also different SMBIOS like Air, BookPro and even iMac but with no luck. Also tried extracting the EDID withing Windows using moninfo and injected it via Clover but no change. Even tried new install of Sierra and Mojave but same problem. Stayed up till 4am last 3 nights in row and really dont know where the issue is. I have some feelings about something to do with the display characteristics or something but no idea. I actually got the laptop after doing one for the 3rd Gen model for a friend friend, except it was a HD 1920x0180 model, and that worked ok. Any help much appreciated. debug_31891.zip
