Hello!

I’m trying to switch from windows to fedora, but I have trouble getting my HDMI port to work. I have looked at other people posts with this problem, but although I follow their solutions it doesn’t seem to work for me.

I have a HP Zbook Power G9 mobile workstation, it has a i7-12700H and a Nvidia A1000 GPU.
Its running fedora 38 workstation (I don’t know if I can see the specific version somewhere) with the wayland windowing system.

I saw people using these commands to provide information so I ran them while I was plugged in with my HDMI cable:

I hope you guys can help me! (and lets hope I didn’t do something stupid)

The only thing I am sure of with what was posted is that the drivers are installed, seem to be loaded, and the nvidia gpu is not in use (smi shows 0%)

This is normally the default for dual-gpu systems since they use the intergrated gpu (iGPU) unless told to use the dGPU.

In my experience (I am not yet a wayland fan) it seems very easy to use the dGPU if you follow the instructions in the link below. Step 8 would be the only one required because you already have the drivers installed.

After you reboot, the procedure there takes effect when you log in with the xorg DE and are not functional when using the wayland DE.

Some have provided instructions to force use of the nvidia dGPU when using wayland, but I do not have a link to those posts and others seem to avoid using that method.

For me, using that linked method and using xorg just works.

Be careful with other people’s “solutions” – many are workarounds for bugs that have been fixed and only cause new problems, and mean that others with the same hardware may not be able to reproduce your issue. Please make sure that your have reversed the non-working “solutions” so you have the same Fedora configuration as other users.

I have tried following the link that you send, but although its definetly using the nvidia GPU now (checked it with the verification instructions in the link). My HDMI port still doesn’t work.

5

Has this changed? There is no HDMI port listed, but lots of DP’s. Did the HDMI port work in Windows? Does your HDMI cable work with a different source and the same monitor (my wife is a macOS user and can provide USB-C-DP and HDMI test signals and cables).

Linux Fix for HDMI No Signal says some vendors have the HDMI port connected to the Nvidia GPU so it is only available with Nvidia active. If that is your case, enabling the Nvidia GPU should have changed the inxi output to add an HDMI port for “Device-2”.

Glitches in linux support for video, sound, and networking are not unusual due to vendors focusing on Windows. I have a bunch of USB dongles for wifi, BT, and sound that get used when internal devices stop working with upgrades. I recently added video adapters (USB-C+DP to HDMI, DP to HDMI).

6

I have run the command again and I don’t think the HDMI port showed up (HDMI is not plugged in on the moment). In windows I have used an external display with this laptop over the HDMI port or/and over the USB-C port. I have a external hard drive on which I can install windows to double check that the HDMI port works for sure.

Here, inxi -Fzxx includes HDMI ports in the “empty” field for graphics devices:

Graphics:
  Device-1: Intel CoffeeLake-S GT2 [UHD Graphics 630] vendor: Dell
    driver: i915 v: kernel arch: Gen-9.5 ports: active: DP-1 empty: DP-2,
    HDMI-A-1, HDMI-A-2, HDMI-A-3 bus-ID: 00:02.0 chip-ID: 8086:3e92
8

It doesn’t seem like my device-2 lists any ports at all were as my device-1 only lists DP ports. I will reinstall windows tomorrow to see if the HDMI port works at all. And then install fedora again just in case i messed something up with other people’s “solutions” which I tried earlier. I will let you guys know how it went.

9

Monitors, input devices, and network are activated before any OS is loaded. This laptop displays BIOS messages on an external (HDMI) monitor at boot time if the lid is closed. There may be “BIOS” settings to choose how BIOS messages are displayed. Sometimes the behaviour of these devices changes when warm booting to linux from Windows versus booting directly to linux.

There are often glitches with drivers that have code sections that have not been updated to run with recent kernels. If the glitch only affects a rarely used hardware configuration it is easily overlooked by kernel developers. I’ve encountered these several times – in every case another user had already encountered and reported the bug, but it takes some time before a fix is available (which is where adapters are a useful interim “solution”).

10

So I have done three things today, tried with a docking station, checked if the HDMI port worked on windows and reinstalled fedora and driver following the guide mentioned in Jeff V’s first reply.

First of all I tried using a docking station at my work to see if the external monitor would work and it didn’t. The mouse, keyboard and ethernet worked but the external display didn’t show up I ran inxi -Fzxx while connected for both wayland and X11.

Second of all I have reinstalled windows to check if the HDMI port works at all and it does. When windows was installed I had no trouble connecting to my external display.

Third of all I went back to reinstall fedora and drivers using the guide in Jeff V’s reply and changed the X11 config again. On fedora the display never showed up. Below again the command “inxi -Fzxx” after reinstall and drivers and such

Should I report a bug and if yes where?

Looks like it has been reported to freedesktop.org:
HP Zbook HDMI detection patch provides a workaround for what appears to be a bug in the BIOS. HP seems uninterested in fixing their BIOS:
HP Zbook HDMI detection, but if HP doesn’t have a reason for this they may eventually fix it when they update the BIOS. The alternative would be to add options to the linux module, but in general linux.org avoids vendor-specific workarounds.

Nvidia has skin in the game, and is in a position to pressure vendors to properly support linux. Check to see if the issue has been mentioned in Nvidia forums both for your HP model and for other vendors who supply the same Nvidia hardware.

Your best short-term solution an adapter that allows your monitor to use one of the other ports.

I have tested the mainline version of the kernel 6.6-rc2 and then it does indeed work.

Thnx for all the help!
