Hello people, first of all, sorry for my bad english, its not my native language…
Ok, i have a Mac Pro 5,1 2010-2012, and i want to use qubes, but every time i click on any option to start installation, i got a black screen.
My Specs are:
GPU RX 570 8gb
Ram 4x16gb 1333mhz (64gb total)
CPU Xeon 6 core six threads
Storage:
120GB ssd
500GB hd
2x1TB hd
512GB nvme
Sorry if i did anything wrong.
When the Qubes OS installation starts, following the GRUB (?) selection, it is not unusual to have a long period where the screen is black. Eventually, the graphical installer starts.
Sometimes the system will freeze with a black screen following installation and a reboot. My Lenovo laptop did that. When the system is turned off by holding the power button down, and then the system is turned back on, you might be surprised to find the system working.
Did I answer your question?
Your system is very powerful and more than enough to run Qubes OS. VT-X and VT-D must both be enabled. Your system has 4 x 8 GB = 32 GB, not 64 GB (!)
Sorry for the basic math error, i didnt noticed haha, but no, unfurtumatly i cant boot the installer, the black screen still happaning 
I tried all the grub options and none of them worked
if you use an usb memory stick that has a LED, is it blinking during the black screen?
Could you try other USB ports?
The LED stopped after the screen goes black, i will test with another usb stick now, and i already tried other USB ports
I tested another usb stick and nothing, i still get the black screen, is there any lernel parameters i should use?
Maybe try to add single to the kernel parameters, that won’t solve the problem but if we could get more information…
Try to change settings in the bios that may be related to boot or GPU if any.
I enterd on the verbose mode, after a 3…2…1… countdown the screen goes black and it freezes
Could you try to boot something like Fedora or Ubuntu and see if they work? This could give some clue about compatibility.
I already installed ubuntu before, the only thing it didnt work by default is the wifi bcm4322 chip, maybe its related?
@solene is right.
We know that you can definitely get to the GRUB menu, which is a good start.
Once you are there, you need to select your option (do NOT press Enter), and then press E. This will allow you edit the configuration.
single should work, but if you can, also try and remove any instances where you see the word quiet as well. That will allow us to see what’s happening.
This will likely cause issues during the initial setup on first boot (when it’s setting up sys-net), but it shouldn’t prevent the ISO from booting. I’d be surprised if it was causing the issue.
Oh how I wish Apple hardware had a configurable BIOS
@EdZiin1007, try adding the following to the GRUB kernel parameters:
nomodesetradeon.modeset=0I have a feeling Linux is trying to interface with a Radeon card as if it were a modern RX card…
I tried all of the kernel parameters, and nothing, same black screen, tried a old Nvidia gt 610 2GB, removed my pci nvme adaptor, my pci usb adaptor and nothing, already tried to blacklist the wifi card…
So, does anything happen if you try to get to a tty (by pressing Ctrl + Alt + F[1-9])?
And what happens if you select the option “Rescue a Qubes OS system”?
The rescue option does not work, i will test the tty now
When you say “does not work”, you mean you get the same blank screen, right?
Just checking…
I tried the tty too, nothing happened…
Yes, the same black screen, the flash drive led turn off…
That’s relevant. It means that it’s not just the display, but the entire machine.
Unfortunately, this sounds a lot like what I encountered with my Apple hardware from around the same age as yours:
The issue is that those Xeon CPUs in your hardware aren’t 1-to-1 with what you’d find in other PC hardware. They were made specially for Apple, and could potentially have some key functions missing (Apple did this a lot with their hardware), that the Qubes ISO is expecting to find, hence the errors.
Give me a second. I’m checking up on how to launch the Qubes ISO in text-mode only…
Ok
I would try inst.cmdline, console=tty1, and if that doesn’t show you anything, try some of the other GRUB parameters listed here:
