RX 6800 XT "no signal" during boot sequence

General system Kernel, boot, graphics & hardware
1

Hi,

I recently bought a few second hand parts and everything is running fine, except the resolution and timing of the GPU’s output is out of range for my monitor during the boot sequence.

In order to access the bios I need to use the TV instead of my Dell SE2717H/HX. The screen is connected through HDMI.

Is there any way of setting the display during the boot sequence? I couldn’t find anything for systemd-boot that would affect the display.

I have updated my bios firmware and checked whether there isn’t a setting that might help, and I’ve disabled the CSM feature.

Any help would be greatly appreciated.

If you are using systemd-boot with dracut try this to see if it helps:

Create a config file: sudo nano /etc/dracut.conf.d/amdgpu.conf

Add: force_drivers+=" amdgpu "

Save and exit nano

Run: sudo reinstall-kernels

Reboot
3

Create a config file: sudo nano /etc/dracut.conf.d/amdgpu.conf

Add: force_drivers+=" amdgpu "

Save and exit nano

Run: sudo reinstall-kernels

Thanks for this! At least I’m now able to decrypt my drive while seeing the prompt. xD

I changed one line according the wiki:
add_drivers+=" amdgpu "

Still no signal for the bios and boot entries.

Yeah, that’s why I deleted it at first. Because I didn’t read the part about you getting no signal (even when trying to go into the BIOS) wrong. So I didn’t think it would help.

You should change it back to force_drivers again tho (unless it causes problems). The wiki is not completely correct in all examples.

add_drivers just adds the drivers to the initramfs. force_drivers will also attempt to load them as early as possible.

You will have to run sudo reinstall-kernels after every time you make changes to that config file to regenerate the initramfs and apply the changes there.

Have you tried turning off FreeSync in the monitor settings?

6

Unfortunately, the monitor doesn’t provide any options for controlling FreeSync specifically.

7

It seems like force_drivers amounts to more or less the same as add_drivers in this instance. The display only turns on at the decryption prompt, right after the kernel selection menu.

I would honestly put the blame on the monitor currently.

I’ve used a 6800 XT for a long time on different monitors and didn’t have an issue like that. They were all connected via DisplayPort tho.

But when I looked up the specs of you monitor it only has a single HDMI port and a VGA port !?!?!

So trying DisplayPort is not an option, obviously.

Maybe the card is busted or one of the HDMI ports on the card is busted. Try the other one if you haven’t yet. Maybe try another HDMI cable or try with the integrated GPU too see of the behavor is different.

You can also try disabling the integrated GPU in the BIOS or changing the settings to give priority to the dedicated GPU.

I vaguely remember when I had an X570 motherboard that the iGPU would take priority by default. And the automated check for which GPU to use would take quite a while. So getting a signal to the monitor was delayed until the OS was booting already.

Thanks! I’ll have a look at the BIOS once I’ve lugged my PC back to the TV. I completely missed the IGFX options, because I didn’t know what to look for.

In retrospect, the monitor wasn’t a good buy. At least I got it for a good price.

I’ve changed the HDMI cable to see if that helps, but still no display.

Will report back once I’ve changed the BIOS settings.

The 5600X requires a discrete graphics card so it doesn’t have onboard gpu. You should set the the Bios settings for gpu to discrete graphics. Secure boot, CSM and Fast boot should be disabled. Nothing is needed for amdgpu to work unless there is some hardware issue that requires a kernel parameter, or there is some hardware issue such as defective part.

11

Hi, thanks for the input.

It appears I don’t have the NB Configuration section available in the BIOS, for setting the iGFX settings. I’m assuming it’s unavailable because it detects that my chipset doesn’t support integrated graphics. Regardless, the default should be disabled.

Secure boot, CSM and Fast Boot has been disabled, but unfortunately I still have no signal during the boot sequence.

12

Maybe it doesn’t show when you have a processor that doesn’t have integrated gpu but that doesn’t make sense to me. My MSI board has the settings and my cpu doesn’t have an integrated gpu either. I’ve never seen this before. If it didn’t have onboard gpu and you set it to that setting it would just boot without video or it would automatically switch possibly. :person_shrugging:

13

Yeah, I had to do a double take just to make sure I’m not going crazy.

I also went through all the other options to see whether the documentation might just be out of date, but didn’t see anything related to integrated graphics or discrete GPUs.

I think I’ll contact Asus support to see whether I’m not missing something.

14

I don’t see anything in the manual either. Are you hooking the HDMI cable from the dedicated card to the monitor? Or did you hook the HDMI cable from the motherboard HDMI Port to the monitor because that is what you would do if the cpu had onboard graphics and you were using that without a dedicated card. If you have a dedicated card it connects from the card to the monitor. Just in case because some people overlook what they do.

15

Sorry for the delay in response.

The HDMI cable has been hooked up to the discrete graphics card.

Also double checked the BIOS on the TV again today, because I saw mention that the NB configuration settings appear once the CSM feature is disabled. Unfortunately, that was not the case.

At this point, I’m okay being able to see the decryption prompt, and I can change the kernel by modifying the entries with systemd-boot or on the TV. Not ideal, but otherwise the system is running 100%.
