On my thinkpad t16, xrandr gives the following output:

$ xrandr --output HDMI1 --mode 1920x1200
warning: output HDMI1 not found; ignoringThis means that I unfortunately am stuck with only using my inbuilt laptop monitor. Further, which may give additional hints, not all of the resolutions given for the internal monitor work:
$ xrandr --output eDP-1 --mode 960x600
xrandr: cannot find mode 960x600Calling lspci gives the following:

Kernel driver in use: i915What could be the problem here? Please tell me if I have missed attaching some useful information.
Thank you in advance for any help you can offer!

I wanted to check if I perhaps had made some mistake during installation. If I, for example, had installed the wrong drivers. So, I booted a Manjaro usb stick. Since manjaro comes with Xorg pre-installed, I got a test case where everything was (presumably) correctly installed by a third party. The problem persisted!
Would this imply that there is some issue with how the kernel or Xorg interacts with the hardware? Or perhaps a hardware problem? Or are there some esoteric extra steps that need to be taken when setting up Xorg for this particular system, unbeknownst to me and the Manjaro devs? I will also try some more remote distro, but it's a shame I can't try it with Windows without editing my hard drive.

Apparently, (part of) the problem appears to have been a bug in the bios. As such, fwupd (partially) fixed it. Xorg now correctly detects the HDMI cable, which was my main issue.
The smaller problem of xrandr still detecting four non-existent displayports and several modes it claims it cannot find persists. I am unsure about the etiquette here, but I'll still mark the problem as solved. Should I need to I can open another issue with an updated, more specific thread dealing with the second, smaller issue.

Hi Swarchden!
I do have a very similar problem with alder lake_UP3 but on a different Linux System.
How do fwupd updated the bios?
...updating something like the bios have to be handled with care, especially when using "non manufacturer tools".
So I'm afraid to brake my system, when updating the bios.
