Has anybody successfully managed to boot qubes on 4.3 alpha with nvidia card?

There were lots of debugging during boot. i constantly saw the message about the signature, but it was solved when i updated bios clock. but the problem persists -
I’ve skimmed through few pages of posts, but except the last one (which has been not attempted) it doesn’t worked. i’ll try to install qubes without nvidia graphcs card, update dom0 and retry it.

puts hand up

Install with AMD GPU, update the kernel specifically to 6.6.68 or above.

Reboot.

Shut down and change out to NVIDIA card again.

Boot.

Work happily.

I have moderate success, but only by disabling it in dom0 (adding module_blacklist=nouveau option to dom0 kernel) and then attaching it to a VM. Obviously this approach works only if nvidia is not the only GPU you have…

I guess you may try by booting installer with kernel-latest (the last boot entry in installer), but there may still be missing firmware in the installer image…

It seems nice approach to remove graphics amd install, and update dom0 to latest or install nvidia drivers, and attach the graphics. I would try it out.

However, regardless of the kernel-latest or verbose boot and install in first menu in installation medium, i found out that either the 4.3 alpha build or the corrupted installation media is problematic, i successfully managed to see post-installation screen and installed template, but instllaer is stuck on cofiguring networking.

How did you boot to the ISO?

Was the AMD card in from the start to that point?

When you are setting up, don’t configure anything except the sys-usb if you want the sys-usb.

Other than that, just install one template, or none.

I often don’t install any templates for the installer, just get the system up.

After that, I install the templates from the ISO myself. Saves time, saves headaches, and takes less time.

Does AMD integrated gpu work for this? I may assume that it’ll won’t work out… While installing making OS work is sufficient with adding x2apic=false by both xen and Linux kernel parameter, but it seems it does not work after reboot.
BTW, I’m using ryzen 7600& rtx 3090 with asrock b850 pro-a motherboard. Is it better to add it for HCL?

Just curious. I updated my Qubes R4.2 some time ago, but had to remove my nVidia card for it to work. Using an Asus W680-ACE with integrated graphics, so no concern to workaround, but was there a change that produced an nVidia to Qubes hardware conflict?

hmm, in my case, ryzen 7600/asrock b850 pro-a, and rtx 3090, it works without any concerns with r2.4 with kernel-latest. no problems, what i initially did was just remove the card while preinstallation/postinstallation and adding it after first boot. setting kernal parameter for hide pci(see 'Creating Gaming HVM).

but, i have trouble installing 4.3 alpha. seeing HCL, trying to debug with it with gemini, nothing worked - i don’t have enough expertise to debug fully on my own. it seemed related to cpu/motherboard issue, since integrated gpu seemed cannot display the display manager. while first boot, adding both xen line and linux line to x2apic=false made it worked, but it seems weird that 1) qubes cannot recognize about 4 GB of ram and 2) it doesn’t display the display manager after second(third, forth, … ) boot. nvidia-troubleshooting doesn’t work at all.

The solution for me was getting the bleeding edge 4.3 release i think from the notset.fr domain
That came with the newest kernel which fixed the issues.
For reference - nvidia GPU, (not iGPU.)
