No HDMI output with Raptor Lake-P on Thinkbook 16p Gen 4

Hi!

Long time (20y+) Linux user here, Fedora newbie :wink: I installed Fedora Workstation on a new Thinkbook 16p Gen 4. I chose 39 because of the recent hardware, for which I want the best support.

Everything is great, except for the fact that I can’t get my HDMI output to work, neither with integrated or discrete graphics card. I am using the HDMI output of the laptop, not a hub.

dmesg is here
journal is there

uname -a

Linux thinkbook 6.5.5-300.fc39.x86_64 #1 SMP PREEMPT_DYNAMIC Sat Sep 23 22:53:02 UTC 2023 x86_64 GNU/Linux

xrandr shows only the integrated screen. External screen and cable are OK though. Is there something simple I overlooked?

Thank you for your help!

You have an nvidia 4060 GPU that is probably dedicated to the hdmi output.

From the dmesg output it does not appear that you have installed the nvidia drivers for that adapter. I don’t think the default nouveau driver is able to support that adapter as yet, and nouveau certainly will not support high quality graphics at all since it cannot support the hardware acceleration even on older GPUs.

It also appears that even the nouveau drivers did not load.

Please install the nvidia drivers from rpmfusion by first enabling the 3rd party repos in gnome software then use sudo dnf install akmod-nvidia xorg-x11-drv-nvidia-cuda to do the install.

Dear @computersavvy thanks!
I did not think that the nvidia GPU could be dedicated to that output. Installing the driver did the trick.

Most optimus laptops are designed for the external ports to be managed by the dGPU (I suspect this is because external screens are larger and often higher resolution than the laptop screen).

Having no driver loaded for the GPU means it cannot function, which led me to the driver issue.

Glad it worked for you. :sunglasses:
