[SOLVED]LM21 - Intel Gen 12 - HDMI not working

Post by FloRath »

Hello together,
although I read a lot of similar topics, none of the ideas worked for me. So I decided to create a new thread and hope for the best! :D

My Problem is the following:
I get a new Lenove Thinkpad P14s Gen3 and installed Linux Mint 21 additionally to the original Windows installation.
If I connect a HDMI Monitor to the laptop it will not get recognized. What seems strange to me, is the fact that

Code: Select all

ls /sys/class/drm
shows

Code: Select all

flow@hive:~$ ls /sys/class/drm
card0       card0-DP-2  card0-DP-4   card1       renderD129
card0-DP-1  card0-DP-3  card0-eDP-1  renderD128  version
No HDMI connection shows up. Is that a normal behaviour?

Additional Information, that might help.

If I connect a HDMI Monitor to the laptop it will not get recognized. What seems strange to me, is the fact that

Code: Select all

ls /sys/class/drm
shows

Code: Select all

flow@hive:~$ ls /sys/class/drm
card0       card0-DP-2  card0-DP-4   card1       renderD129
card0-DP-1  card0-DP-3  card0-eDP-1  renderD128  version
No HDMI connection shows up. Is that a normal behaviour?
Welcome to the forum, FloRath.

This is not the first time I've seen this happen on LM21, but I'm not yet sure why it is happening. After booting with the Monitor attached, let's check the Xorg log to see if there might be a clue as to why that is happening. X Server runs the graphics in Linux Mint. Please use this command in a terminal to upload the X Server log file to termbin:

Code: Select all

cat /var/log/Xorg.0.log | nc termbin.com 9999
It will return with a url address that you can post in your next reply.

The subconnector types do show they support HDMI.

Code: Select all

DP-1 disconnected (normal left inverted right x axis y axis)
	subconnector: Unknown 
		supported: Unknown, VGA, DVI-D, HDMI, DP, Wireless, Native
DP-2 disconnected (normal left inverted right x axis y axis)
	subconnector: Unknown 
		supported: Unknown, VGA, DVI-D, HDMI, DP, Wireless, Native
DP-3 disconnected (normal left inverted right x axis y axis)
	subconnector: Unknown 
		supported: Unknown, VGA, DVI-D, HDMI, DP, Wireless, Native
DP-4 disconnected (normal left inverted right x axis y axis)
	subconnector: Unknown 
		supported: Unknown, VGA, DVI-D, HDMI, DP, Wireless, Native

Thank you for your response!

Here the link https://termbin.com/7x01

what I forgot to mention, Display works fine when using windows. So cable and port are ok.

The information in the Xorg log was similar to what is showing in inxi and xrnadr.

In the comments of this blog post I found someone who said they did not get the HDMI port working on Ubuntu, but I do not know if that one the same CPU as you.

Are there any options in BIOS/UEFI with regards to either switching GPUs or related to using ports for displays? If so, what are the options?

No, could not find anything GPU or port related.

I really think, that there should be an HDMI connector entry here:

Code: Select all

flow@hive:~$ ls /sys/class/drm
card0       card0-DP-3  card0-DP-6   card1       version
card0-DP-1  card0-DP-4  card0-DP-7   renderD128
card0-DP-2  card0-DP-5  card0-eDP-1  renderD129
Checked everything on a Lenovo Thinkpad P15s Gen2, which is basically the same machine with an 11th generation intel chip. And the HDMI connector shows up in the drm folder.

Also tried an older NVIDIA driver.

The thought that this issue has something to do with the fact the Gen3 is a 12th-gen Intel CPU and perhaps the graphics driver for it is written differently due to the two types of cores crossed my mind. There is also the possibility there is something different in the bus hardware because of the two types of cores. I did a lot of searching yesterday, but was not able to find any clues as to why the HDMI might not be showing.

Perhaps posting a question on the Lenovo community forum will get the attention of someone who might know why this is happening.

I will do some more searching to see if I can find more info.

Just the regular UEFI firmware update or was it a specific type of firmware? (Sometimes there are separate ones which is why I ask.)

Glad to hear it is resolved. Please go to your first post in this topic, click the pencil icon, and add [SOLVED] to the beginning of the title so others know you are no longer seeking help on this issue.
