Re: Mint 20 Display port ryzen 5

I am not familiar with the specs on that laptop, but the graphics information seen by Mint indicates is only has one graphics device. Is that correct?

I ask that because some laptops have an onboard graphics device and a separate graphics card. In those cases there is usually a BIOS setting which toggles between the separate card and a "hybrid" mode. The separate card is sometimes what drives ports to external displays, so if the laptop has two cards and only one is being seen by Mint that could be a reason the monitor attached the displayport is not being used.

I suggest checking /var/log/Xorg.0.log for (EE) or (WW) messages. If you would like us on the forum help review that logfile, use this command in a terminal to upload it to pastebin:
cat /var/log/Xorg.0.log | nc termbin.com 9999
The command will return with a url address which you should post in your reply.

The display portion of the graphics information is showing only the two monitors which appear to be the same resolution. I expect those are the ones you also see in the Display app.

Hi I would love to have some help from the community

Here is the link for the xorg dump
https://termbin.com/1ztx

This is not actually a laptop it is one of the new mini desktop computers, it has no dedicated graphics cards only the apu provided one.

It supports 4 display devices two hdmi, one display port and one usb c type to display port

if I only connect the display port, I am using a display port to dvi cable, I now am the proud owner of 3 different ones all of them behave the same they work fine with the bios startup the initial linux boot, then the screen goes blank but the monitor still thinks something is being displayed.

if I connect the two hdmi monitors and the display port then the screen never activates and does not show up in display management at all!

Thanks for the correction. I looked up the 3550H on the AMD website and it came up as a mobile processor listing rather than a desktop listing. That might be why inxi is showing your computer as a laptop.

I found some reviews on its predecessor, the Beelink GT-R which indicated no problems with Ubuntu 20.04, but it seemed that person may have only been using the HDMI ports. I had no luck finding mention of someone using the displayport.

The XOrg.0.log file is matching the xrandr output in that both are showing the two HDMI ports connected and two DisplayPorts as disconnected.

Let's see if sudo lshw -C display shows all three monitors.

Here is the output from the commands you suggested. I really hope it helps, I have ensured the latest amdgpu drivers are installed etc.

The Xorg.0.log lists the EDID for both monitors connected to the HDMI ports but not the DisplayPort.

What resolution is the monitor connected to DisplayPort using?

Your inxi shows your computer using the amdgpu module from the kernel. Did you install drivers after you ran inxi?

The XOrg.0.log file you posted is showing the amdgpu 19.1.0 module which I think is the 5.4 kernel version. I did wonder if maybe a newer driver might have changes to displayport support, but when I checked the AMD website, the AMD Ryzen™ 5 3550H Drivers & Support only lists drivers for Windows.

The output of apt show xserver-xorg-video-amdgpu lists the specific amdgpu module you have installed. If you have something higher than 19.1.0 then it's possible the output of XOrg.0.log might be different.
