I have a Laptop with Geforce 960m + Intel 6700 HQ, but unfortunately I haven’t been able to boot Linux on this machine after some recent driver updates (470, 535, 550 series, to name a few).
I’ve so far tried Ubuntu 22.0.4, 24.0.4, Manjaro 24.0.5 and Fedora 40. All to no avail.
So there is no option for disabling or enabling, but only for DVMT Pre-Allocation.
Furthermore, if I switch away from intel vi prime-select nvidia from terminal, I get a blackscreen even when booting via recovery mode. So not sure if disabling intel could work as a workaround.
1、Maybe you can install the nvidia 560 driver without the nvidia card plugging in fresh fedora40 installed,
2、then power off,and plug nvidia card,
3、reboot to see
