Installing updates on my home server broke it, something with LVM doesn't work anymore. So I did the usual thing: Prepare a USB installation device and boot it, in order to fix stuff. Sadly, this doesn't work for reasons unknown to me.
What I have:
Intel D2500HN Motherboard, with literally no hardware except for a keyboard. There is on-board intel graphics and a single VGA port, which is the only display port.
What I observe:
Booting the installation medium gets me the grub or UEFI boot screen. If I select one of the options, the kernel is loaded, the drivers are loaded and when the screen is about to switch to a higher resolution, the signal to the screen is lost. I can type 'poweroff' blindly and it powers off - so the shell works, but the screen doesn't.
What I tried:
I tried
UEFI/Grub
32 bit / 64 bit
i915.modeset=0, nomodeset,and combinations of them
video=VGA-1
vga=771
fbcon=map:1 / 0
acpi=off
various settings in the bios (which I updated to the latest firmware)
older arch ISOs (one from 2015 and 2014 each)
Honestly, I don't know anymore how I installed the system initially. I can't remember having that issue, but now it appeared without any change in hardware.
Do you have any suggestions what else I could try?
/e: I have worked around the issue by building a custom arch ISO image with SSH enabled, so that I could remote control the arch live instance. The issue is still unresolved, though.
