davidfrei7as Posted October 13, 2021 Author Share Posted October 13, 2021 @Hervé I add the flag using propper tree, save changes and reboot. but, when in the system I was checked the boot args and igfxonln=1 disappear. Link to comment Share on other sites More sharing options...
Administrators Hervé Posted October 13, 2021 Administrators Share Posted October 13, 2021 Sorry, I don't understand what you're trying to say by "igfxonln disappear". Disappear from where? Make sure you save your OC config properly and reset NVRAM on reboot. Link to comment Share on other sites More sharing options...
