Enabeling a second monitor using Linux Mint and dual boot

Graphics / Linux Linux
#1

I installed a dual boot on Lenovo Thinkpad P16s with Linux Mint as an additional operating system. The notebook uses an NVIDIA T550 Laptop GPU. I installed Nvidia drivers (525.60.11).
I do not manage to use two monitors. The help menu provides as follows: “Screens
This is the number of X Screens on the display. (When Xinerama is enabled this is always 1).”

Nvidia bug report is attached.

Online research pointed to etc/xorg.conf which does not exist on this machine.

Any help on how to enable a second monitor is highly appreciated.

Best,
Till

first off, is the external monitor plugged directly into the nVidia GPU, or does it go through an integrated GPU (intel, AMD?)? You will have to research this (specific to your laptop model). Second, at least on my Lenovo Legion 5 Pro…I have a BIOS option to run hybrid or discrete-only graphics (mine has a MUX switch also, and the external ports are routed to the discrete GPU).

You shouldn’t need an xorg.conf in general. You do, however, needed to enable kernel modesetting (requires a kernel parameter during boot) for the nVidia drivers to work correctly.

Thanks for your quick reply.

It seems to me that modeprobe is enabled. nvidia-graphics-driver-kms.conf reads as follows:

This file was generated by nvidia-driver-525

Set value to 0 to disable modesetting

options nvidia-drm modeset=1

I have attached the data sheet. That is all I can find about the nVidis GPU.

I checked the BIOS: you may change between an external display and the Thinkpad display during boot time. I tried but this didn’t help after boot (external screen worked during boot, both displays black after boot).

I checked with dmesg and found the following information:
[ 0.865276] pci 0000:00:07.0: DPC: RP PIO log size 0 is invalid

Not sure if this has a meaning.

Would it be helpful to disable Xinerama? If so, how to do?

#4

All your external connectors are on the intel igpu, the nvidia gpu has none. Since you have a ver new 12th gen cpu, please upgrade the kernel using the liquorix ppa and check if the hdmi port starts to work.

#5

I installed Liquorx (Kernel: 6.1.0-3.1-liquorix-amd64)

How to enable HDMI? Do you think setting Nvidia GPU as primary card would make sense (How to Connect Your Linux Laptop to an External Monitor (Fix for HDMI "No Signal" Issue) - 9to5Linux)?

As I already said, all outputs are connected to the intel gpu, the nvidia gpu has none so fiddling with the nvidia driver won’t have any effect.

Since kernel 6.1 doesn’t fix this, it might be due to a known Insyde bios bug. Please check for a bios update. Please create a new nvidia-bug-report.log running the liquorix kernel.

Thanks for your quick reply, well appreciated.

I checked for a BIOS update and installed the most recent version (1.25). Interesting: the notebook is intended to work with Ubuntu Linux (according to their BIOS update information). I guess I should contact their support.

Please find attached the newest bug report using the Liquorix kernel.

Yes, Thinkpads are in Lenovo’s “Linux program” so they’re guaranteed to work but from experience I know they don’t really test this thoroughly so you might have to order a fix or two…
First, you should rule out a general hardware defect, e.g. installing Windows. If that’s working, you should contact Lenovo support and also report a bug with the intel i915 driver https://gitlab.freedesktop.org/drm/intel/-/wikis/How-to-file-i915-bugs

My goodness! BIOS update to 1.30 did the job (BIOS Update (Utility & Bootable CD) for Windows 11, 10 (64-bit), Linux - ThinkPad T14 Gen 3, P14s Gen 3, T16 Gen 1, P16s Gen 1 - Lenovo Support DE). Thank you for your help!
