[Lenovo ThinkPad P1 Gen 2] HDMI port can't be found

Thanks for the bug report.

It appears the whole HDMI port is missing, and we're not just failing to detect a monitor. So that would be a kernel bug I think.

This change was made by a bot.

Could you install wayland session and try it?

If you still find this issue, please add drm.debug=0x04 in cmdline and highlight the log when plugin HDMI.
Upload the log of "journalctl -b0".

It appears this laptop usually comes with a second GPU. If that discrete GPU has been disabled somehow such that the kernel isn't reporting it, then any HDMI port connected to that GPU will also be missing.

Hi,

I have tried adding drm.debug=0x04 and connecting to HDMI.
Log is in the attachment.

Thank you and regards,
Igor

Error in log:
nvidia-settings-autostart.desktop[2939]: ERROR: NVIDIA driver is not loaded

nvidia-drivers-440 should be installed to support external display output.

Igor, please open the app 'Additional Drivers' and use that to install the Nvidia driver. Then reboot and tell us if the problem persists.

Hi,

Actually I have worked with Intel driver.
Does that mean that Intel can not display to external display ? (I use it
as it seems to use less energy than nvidia)

Now I have switched to nvidia with nvidia-settings (to Performance mode)
Rebooted + drm.debug=0x04
Still no picture on external monitor.

Output of drivers is below. Should I uninstall or switch to 435 ? I am not
sure how to switch driver.

How I can try Wayland, do you have somewhere steps for preparation ?

After installing nvidia-driver-440, please reboot and then run:

  xrandr > xrandr.txt
  lspci -k > lspcik.txt
  journalctl -b0 > journal.txt

and attach the resulting text files here.

I don't find Nvidia card in lspci. Are we sure there's an Nvidia card in the system?

See comment #6, which is also based on:

https://psref.lenovo.com/syspool/Sys/PDF/ThinkPad/ThinkPad_P1_2nd_Gen/ThinkPad_P1_2nd_Gen_Spec.PDF

Yeah it's possible there is no Nvidia GPU, although comment #10 also suggests there is one. Just seems the more likely explanation right now.

Igor, please check the system BIOS to ensure the discrete GPU is enabled.

Hi Daniel,

I changed discrete GPU to enabled.
Please find attached file for requested details.

Thank you,
Igor

Thanks! It exists!

01:00.0 VGA compatible controller: NVIDIA Corporation TU117GLM [Quadro T1000 Mobile] (rev a1)
 Subsystem: Lenovo TU117GLM [Quadro T1000 Mobile]
 Kernel modules: nvidiafb, nouveau, nvidia_drm, nvidia

But nouveau doesn't seem to support it. So please now install the Nvidia driver through the 'Additional Drivers' app.

Or uninstall it, and reinstall it.

Hi Daniel,

I did the changes in 'Additional Drivers' + reboot.
I attached journal.

Thank you,
Igor

It appears Xorg is not working at all now, like the Nvidia driver isn't installed properly.

Please start by running:

  lspci -k > lspcik.txt

and send us the resulting text file, so we can verify the kernel is OK now.

Then try:

  1. Uninstall the Nvidia driver.

  2. Reboot.

  3. Find any Xorg config files you might be created directly or indirectly and delete those. If you don't know what they look like then don't delete anything.

  4. Reinstall the Nvidia drive via 'Additional Drivers'.

  5. Reboot.

Oh, did you accidentally turn off the integrated Intel GPU when you enabled Nvidia? We need both turned on at the same time. Check your BIOS.

Hi Daniel,

I found workaround.
Discrete graphics in BIOS didn't have impact in my case.
I didn't work with built-in (Intel) only graphics.
Needed "nvidia" or "on-demand" (ex: /usr/bin/prime-select on-demand)
Disabling Secure Boot was required to make it work.

Thank you,
Igor

It sounds like you just needed to figure out how to enable both GPUs simultaneously... Is there any problem left to solve now?

Hi,

No, I am ok with this constraint (no secure boot if HDMI needed).

Thank you,
Igor

Hi,

I have a very similar problem and noticed the following:
My external display is working with Nvidia "Performance Mode" only. In "On-demand" mode, I have a black screen that it is not detected in Ubuntu system settings, although it is detected by Nvidia X Server Settings.
As if we needed a parameter in On-demand to force HDMI interface to start with Nvidia card and not Intel.

Any hints about this?

@Igor, are you sure that you are in "On Demand" mode? I realized that it automatically switches to "Performance Mode" when we change the driver.

Thanks,
Thierry
---------------------------------------------------
My config:
- Lenovo Thinkpad P1 Gen2 with Nvidia Quadro T2000
- Secure Boot Disabled
- Nvidia driver 440 activated

Hi Thierry,

From memory I did set "on demand" mode and it worked correctly.

Now it is a strange situation, kernel 5.4.0-28 is the latest that boots
correctly in my setup if only built in screen (on later versions, it hangs
shortly after Linux boot started, Lenovo sign still there and progress
circle not shown anymore)
Latest kernels boots correctly if there is external screen plugged by HDMI
(so, maybe "hung" from 1st case it is just that still somehow expects
external screen...)

Regards,
Igor
