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

Although I still see the weird dmsg errors, I found the culprit...  I removed "irqpoll" from the linux boot parameters:

I have no idea why it was affecting, it's supposed to help, rather than affect...  I've always used it (since I found issues with mintbox 2 and another HP elitebook laptop), and had worked fine till now...

Thanks !
