I have several of these Lenovo Thinkcentre M700 mini-pc around, been
running Debian 12 on them just fine. A couple days ago I grabbed another
one off the shelf and it still had Windows 11, that was working. Argued
with it a bit till I remembered 'enter' key gets me into bios to disable
secure boot. I wiped it and installed Debian 12.9 and now it boots but I
get no graphics. Vt-d was disabled. I tried enabling it, still no
difference.
I ssh into it from another machine and I see it even detects my monitor:
me@debian:~$ inxi -GSaz

I finally got graphics with a live boot Ubuntu 13.10 but only in safe
graphics mode. Ubuntu reported running x11 and for graphics it says
'software rendering' inxi wasn't installed; I tried installing but it
failed. So much for ubuntu.
I did some searching and found some suggestions: I need to enable or
disable igd in bios. Neither seemed to change my problem. Another said
purge nvidia drivers. So I did:
sudo apt purge *nvidia*

As far as I can see, there is no nvidia gpu. Their is no graphics card
attached to the motherboard, and only the intel is reported in sudo
lspci -v:

I looked over dmesg and nothing jumps at me. Here is a bit of it:
