evy0311 Posted September 25, 2019 Author Share Posted September 25, 2019 Just tried with what you said and sent. Unfortunately the system did the same backlight thing, and this time it even kernel panicked, although I can't tell what caused it to panic though since I can't see the display. Could it be a BIOS setting? I matched mine to the ones from the 7490 guide and then also modified them to be what you told me. I appreciate all the help so far, hopefully we can figure this out Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted September 25, 2019 Moderators Share Posted September 25, 2019 Check to see if there's a newer BIOS available and update to that. After successfully upgrade, set it to LOAD Defaults. Apply Reboot back to the BIOS Set it according to 7490. It's the same for all the Dell's. Mainly just set it to UEFI enabled Legacy Options ROMs disabled (might be default) AHCI enabled Secure Boot disabled CPU XD enabled Wake on LAN / WLAN / WWAN /USB Disabled Link to comment Share on other sites More sharing options...
evy0311 Posted September 26, 2019 Author Share Posted September 26, 2019 Hi Jake! Unfortunately updating the BIOS and setting all the BIOS settings to the desired ones still yielded the same results. Am I missing something? Is this an issue somewhere with my ACPI patching? Like is this an issue with that or is it an issue with a setting or boot flag somewhere? Or should I remake the installer? Thanks so much again. Link to comment Share on other sites More sharing options...
evy0311 Posted September 27, 2019 Author Share Posted September 27, 2019 Would anyone happen to have any more guidance? I've been messing around with the config.plist as well as some ACPI patching with no luck, the screen still behaves the same way. Link to comment Share on other sites More sharing options...

evy0311 Posted September 27, 2019 Author Share Posted September 27, 2019 Jake, thanks for the reply. I think we may be getting somewhere. When using that config.plist. I have attached a screenshot of what happens now. The system doesn't flicker but stops after loading the acpi tables. Is this now an issue of something with the acpi or is it still a config issue?
