[arch-general] [grub] how to make grub use the integrated intel gpu, rather than the discrete nvidia one?

[Javier]

oh well.

Found out by disabling both, legacy and secure boot on the bios, I got intel gpu as the one used by grub.  But then I realized I could actually select it on the bios, though it was sort of misleading to me, it said something like HMU, or similar, whereas the other options were like hybrid, the discrete gpu, or auto, where auto was the default.

So that's better.  But I guess I have a messy bios, which windows don't care about?

I still get random freezes when doing init, and some times even a backtrace dump.  When not getting into that, I'm seen several errors on dmsg:

> % sudo dmesg | 'grep' -i -e error -e bug -e fail

I guess I can start a different thread about this, and close the grub one...
