iGPU and DGPU

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hello,
I'm able to set in BIOS that when PCIE GPU is connected but iGPU will be used instead.
I'm able to run WIndows just fine even when both cards are active with such settings. Hurray!

Problem is when I try to access LUKS encrypted disk on XEN during boot up process.

1. POST visible on IGPU
2. GRUB visible on IGPU
3. Initialization on IGPU
4. ... Just when its asking me for password to the disk, screen if frozen with snapshot of information from point (3.
5. I'm stuck.

When i change monitor from IGPU (lets say HDMI) to DGPU (DVI) input, I can see the prompt for the password.
I don't want to be asked for password on DGPU, why motherboard decided against the BIOS settings?
I can't seem to have any control over it. How come? It is big deal.

I had ASUS in the past, and i had 0 issues with this. I got myself into low price you asked for your card... Can you help?

p.s. stupid solution is to open my chasis and remove DGPU phisically, so it works on iGPU for sure.

	Pull the card apparently. Sides, why the big deal yanking it if it will not be used anyways?
