I am using the clover "Debug_25255 (with config_3121 + trackpad fix)" of post
3 with addition of "SSDT-PNLFCFL.aml" as described in post
7.
The first time I can boot (with "config_3121 trackpad.plist") and the graphic card works fine, as you can see in the screen shot ("UHD Graphics 620 (Whiskey Lake) 1536 MB") and no flickering at all.
However, when I reboot, I get a black screen after the "verbose" phase of the boot, i.e. I do not see the apple and the progression bar anymore (black screen).
I can still boot with "config.plist", but without graphic acceleration then.
I have the feeling there is something wrong with the screen's backlight, I mean the notebook is booting also the 2nd time but I do not see anything (the backlight keys do not respond). That's because I have tried playing with the backlight settings while still in clover, before starting booting Mojave, and sometime I managed a 2nd boot (with "config_3121 trackpad.plist"), but I did not understood why and how to reproduce the failure.
If I replace the "used" EFI folder with a "fresh" original one, again the notebook boots the 1st time only (with "config_3121 trackpad.plist").
Notebook: DELL Inspiron 7580 with Intel Graphic UHD620 and Nvidia GeForce MX150
maxOS: Mojave 10.14.6
Attachments:
- "EFI_orig", before the 1st boot, it will boot the 1st time (with "config_3121 trackpad.plist")
- "EFI_after_1stboot.zip", this is after the 1st boot, it won't boot anymore (with "config_3121 trackpad.plist")
Any idea how to solve the problem?
Many thanks in advance for any support or suggestion.
