![]() I *know* when gpu-power-prefs has been reset, because if I do a normal boot, I get the same old behaviour - ie, the machine mostly hangs on boot because of the state of the dGPU. When I have been booting from grub, and the screen goes black, what's happening here is that the nvram gpu-power-prefs has been reset back to the default (this seems to happen quite a lot, at least while doing boot tests etc). I removed the boot stuff for now with your instructions above. ![]() SIP is left disabled here, at least for now. Edit, some additional information as I have started to understand the behaviour a bit more:įirstly, I'm using your modified grub.cfg posted above, but I think the following would work with the previous ones as well.
