Comments/Problems:

Installing debian testing (Trixie) with the "graphical install" option is not possible, the process stops immediately after launch, with a black screen with various errors in the same screen(perhaps from the x.org server) including:
"Fatal server error: no screen found (EE)"
and lastly:
"(debconf:841): GTK-WARNING: 16:05:14:030: cannot open display: :0"
and the error recurs in an infinite loop.
At this point the PC is blocked and a hardware reset is required to restart.
ISO image verified with sha256.
I attach photos of the screen on which the block of system occurs immediately after launching the graphics installation.
Thank you

FWIW I can reproduce this in a virt-manager/QEMU x86 virtual machine
with QXL graphics. It does not happen with virtio graphics (which uses
modesetting) though.

I can switch to the shell in tty2 with Ctrl+Alt+F2.

Hello,

It also happens on Thinkpad T480 notebooks and Acer SWIFT 1, both with intel graphics.

Thank you
Diego
