Qubes R3.1 : black screen at luks prompt at first reboot after install

[fkhsr...@riseup.net]

Hello.

I have installed a couple of times Qubes R3.1 on my machine without
problem. I messed around with those installs and therefore decided to
clean install again.

The install process still terminates correctly but on first boot i just
get a warm black screen. When i press [echap] i get to the text mode
prompt of luks which doesn't seem to respond to keyboard input.

I have checked my bios settings : all virtualization tech enabled
including IOMMU ; legacy+uefi mode ; IGP mode (i disabled my strong GPU
in favor of the iGPU solution but did not physically uninstall strong
GPU ; want to play with PCIE passthrought) ; i installed from a usb 2
stick on a usb 2 port (but did not disable usb 3 support in bios).

I verified the signature (although i have no trust path) of the ISO it
was correct. I used Ruffus 2.9p in DD mode to burn the image.

My hardware setup :

* MB : MSI Z77 G45
* CPU : core i5 3550 (non k for IOMMU support of course)
* HDD : WD Caviar Green 2 TB (i know ; it IS SLOOOW)
* GPU : AMD R9 280X (disabled in bios for the install)
* KBD : Logitech G15 refresh keyboard
* MOUSE : Logitech G500 mouse

Thank you ; ask me for any missing information.

Hello.

I have physically uninstalled my dedicated GPU and it works. Most things are
not worth preserving. Althought it would be cool to run D3D heavy games in
domU. Label device as "dirty" and do not allow for it to attach to dom0.

Just som random noise I guess..

Good luck.
