[POSSIBLE UPSTREAM BUG] AMDGPU doesn't detect monitor 90% of the time

Hi,

So I recently built a new computer with an AMD Radeon RX 570 graphics card in it. Unfortunately, I have been struggling quite considerably with getting it to work. 90% of the time, when I boot up Linux, the GPU doesn't detect the monitor at all and I have no clue what's going on. The BIOS is always visible, as is the GRUB menu, but after that point it just sorta stops.

I'm essentially certain that this is a driver problem, because this is the third distro that I've tried (previous being Debian and Kubuntu) and I've had the same issue on both of those as well; the driver is the only consistent thing left. I'm using the HDMI output on the card, because I have no monitors that can work with DisplayPort. Fortunately, I do have SSH access, so I am able to work on this, although it's clearly not ideal.

Here is the dmesg output (no I don't know what's up with all those reset USB device messages), here is the result of lspci -nnk, and here is Xorg.0.log. If any additional logfiles are needed, please tell me and I can provide them upon request.

Thanks!

UPDATE: For anyone else experiencing the same issue (I do hope not), this appears to be a kernel bug still present in 5.5-rc2. I have reported this upstream.

Re: [POSSIBLE UPSTREAM BUG] AMDGPU doesn't detect monitor 90% of the time

As a work around does adding the kernel option amdgpu.dc=0 allow more reliable detection?
How long is the HDMI cable and what is the native resolution of the display?
What range of kernel versions has the issue been present on?

Re: [POSSIBLE UPSTREAM BUG] AMDGPU doesn't detect monitor 90% of the time

From Xorg.0.log you can see that there is no connection via hdmi:

Try to change the hdmi cable, and maybe create a 50-monitor.conf in /etc/X11/xorg.conf.d/ where you specify the characteristics of the monitor. Automatic EDID recognition does not seem to work.

Just did a bit of power cycling to test, and it does appear to be working with that kernel option? The computer seems slower, though, although that could just be my imagination honestly. Not sure what that does.

The cable is about a metre long, the display is 1080p. I know the cable is fine, because I have a really old and terrible desktop with an HDMI port and that has never once failed to work (that computer uses intel graphics).

I can confirm the issue is definitely present on 4.19 (Debian Stable), 5.3 (Kubuntu 19.10), and 5.4.3 (Arch).

I've tried a different HDMI cable and that didn't do much good. Messing with xorg.conf made it work 0% of the time, as opposed to 10%, unfortunately. The recognition does work occasionally, but not very often, which is just the weirdest thing to me...

Re: [POSSIBLE UPSTREAM BUG] AMDGPU doesn't detect monitor 90% of the time

Is the internal power connector connected to your graphics card?

Does your computer work with a different monitor?

Re: [POSSIBLE UPSTREAM BUG] AMDGPU doesn't detect monitor 90% of the time

The journal indicates the problem is at low-level , not Xorg. The fact that  amdgpu.dc=0 worksaround does match with  a cause on kernel module level or even closer to the hardware.

If I read logs correctly you have an Asus PRIME B450-PLUS motherboard and are running the 2006 firmware from 2019/11/25 .
Asus released firware version 2008 on 2019/12/11 , https://www.asus.com/us/Motherboards/PR … Desk_BIOS/

Try updating to that version.

Yes and no. The actual HDMI port seems to work, as the BIOS never has any difficulties, and I'm using the graphics card to look at the BIOS (there's no integrated graphics on the CPU).

Hrm, okay. I tried updating to that firmware, removed the amdgpu.dc=0, and it still had the same issue. Replacing amdgpu.dc=0 made it work again.

I was having the same issue when I just got the motherboard, so I tried updating the BIOS then, but nothing unfortunately.

So presumably, because amdgpu.dc=0 works, that means it's to do with Display Core?

Re: [POSSIBLE UPSTREAM BUG] AMDGPU doesn't detect monitor 90% of the time

Yes amdgpu.dc=0 disables use of the display core.  Please post the dmesg from a boot without amdgpu.dc=0 instead with drm.debug=0x1e log_buf_len=2M
This should produce much more output (quote possibly too much) from the amdgpu module.

Behold, the world's longest log file. Apologies for using pastebin.com, I'm not aware of another decent pastebin now that ptpb.pw has shut down.

Re: [POSSIBLE UPSTREAM BUG] AMDGPU doesn't detect monitor 90% of the time

Thank you for the dmesg,  can post a dmesg with all the parameters for comparison e.g. amdgpu.dc=0 drm.debug=0x1e log_buf_len=2M

Re: [POSSIBLE UPSTREAM BUG] AMDGPU doesn't detect monitor 90% of the time

Looks like that one is without amdgpu.dc=0 .

Are you using any kind of firmware overclocking options : processor, memory, videocard ?
especially overclocked memory can have all kinds of weird effects.

No overclocking is going on, at least that I know of anyway.

Re: [POSSIBLE UPSTREAM BUG] AMDGPU doesn't detect monitor 90% of the time

So with amdgpu.dc=0, the GPU is able to detect the monitor, but without, it isn't? God, that's bizarre. Would that be a bug, or?

Re: [POSSIBLE UPSTREAM BUG] AMDGPU doesn't detect monitor 90% of the time

Yes, but that doesn't help much with finding the cause.

amdgpu has lots of kernel paramaters, https://www.kernel.org/doc/html/latest/gpu/amdgpu.html that influence behaviour.

They are above my skill level though.

Could you try with a different monitor ?
Can you put the videocard in another system for testing ?

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.


(A works at time B)  && (time C > time B ) ≠  (A works at time C)

Re: [POSSIBLE UPSTREAM BUG] AMDGPU doesn't detect monitor 90% of the time

I would suggest trying linux 5.5-rc2,   Unofficial_user_repositories#miffe contains the linux-mainline.
If the issue is present in 5.5-rc2 then I would report it upstream to https://gitlab.freedesktop.org/drm/amd/issues including both dmesg outputs.

Trying other monitors (including TVs) give the same results, the only difference being slightly different messages for what monitors are connected obviously.

Aaand it's present in 5.5-rc2. So it's almost certainly a kernel bug! HOORAY /s

Going to send in a bug report after I post this. Thanks for the help, guys.
