Since an update some weeks ago my HDMI output won't connect to any beamer or screen anymore:
> xrandr --output HDMI2 --auto --right-of eDP1 --verbose
screen 0: 6016x2160 1504x540 mm 101.60dpi
crtc 1: 4096x2160 30.00 +1920+0 "HDMI2"
xrandr: Configure crtc 1 failed
crtc 0: disable
crtc 1: disable
crtc 2: disable
screen 0: revert
crtc 0: revert
crtc 1: revert
crtc 2: revertMy laptop is a Lenovo T460s. Its Mini-Display-Port and all the Display-Ports on my docking station still work.
Here's the output of xrandr when a screen is connected to HDMI2:

As you can see, the screen is detected, but what's missing is the line for CRTC.
I have no idea how to fix it. You?

The first line on that output is from 56065.799850 I want to see the start of dmesg to see output relating to the kernel initializing the GPU.
It does appear you CPU is overheating from the dmesg posted.

Ok. I ran
journalctl -o short-precise -k now:

I see these overheating warnings since when I installed ArchLinux two years ago. My laptop never gets hot and the fan is off most of the time. It's also fast and I never felt this "throttling", so I didn't gave it much attention.

Not seeing anything wrong in the journal. What about Xorg.log?

Again, updated my system, but the problem still appears.
Here's the Xorg.log
