Seems similar to others, so, will continue to monitor. The monitor does display in “Display configurations” under KDE and is selected as “enabled” if I disable it, the monitor goes into power-saving, so it’s getting some sort of signal, but not what it needs to display anything.

It works fine under windows.

What do you mean by “working sort of”?

What do you mean by “it’s better”?

Asking because we can help you better if you can tell us the full issue / story

So it was working sort of in that I had some sort of script that I’d installed (optimus switching if I recall) that let me switch between the two GPU’s that are in this machine, so if I wanted to use the monitor, if I swtiched to the Nvidia GPU (and rebooted) then I could use the monitor, and then when I wanted to use the laptop by itself (and didn’t need the Nvidia) I could switch back to the AMD GPU (and reboot) it would work power-saving.

Edit: Think it was this GitHub - dglt1/optimus-switch-amd-sddm: WIP optimus-switch for amd/nvidia hybrid laptops using SDDM. that I was using to switch between the two GPU’s

What’s better (and not sure if it’s the 450 drivers, or the 5.8 Kernel) is it does now detect the HDMI port (it didn’t used to see it at all). Appreciate any thoughts.

5

One further note, I did try the 5.9 kernel just for curiosity, that seemed to be worse, didn’t even seem to see the monitor (no power-cycling)

Hi!
Using optimus switch is just other way to use dual graphics, it isn’t worse or better, just other way. I’ve been using it for a year without problems, imho, it’s more better than prime or others ways to use dual graphics. It help you to save a lot of battery, but like my pop used to say, for likes… asses, everyone have one!!

7

But Optimus Switch requires that I reboot every time I change, to me that’s worse, I want to go from using the AMD graphics because I’m using the laptop as a real laptop, to using it more like a desktop (plugged into a monitor) to playing some games using the Nvidia graphics, back to using it as a laptop without having to constantly reboot.

Hi|
Yeah, that’s right! Depends of you needs or your likes (like a said in my previous post ). Im usually use it as “laptop” and I’m no gamer so igpu is enough for me. I use dgpu only when I need the hdmi output so I rather switch than other way.

About 450, did you use the hybrid driver?

9

Yes, the two drivers installed are the video-hybrid-amd-nvidia-450xx-prime and video-linux. Video-linux is only there because it was a dependency for the other driver.

I’m also has this problem - black screen on HDMI output.
I have Ryzen 5 with Vega 8 and NVidia 1650 Max-Q (with HDMI) on my laptop, and after installing driver “video-hybrid-amd-nvidia-450xx-prime”, I have features to work with my dgpu. But, when I plug in HDMI display, there is just black screen. It’s detecting by “xrandr” as “HDMI-1-0” (with correct info about display), but also “HDMI-1” detecting as “disconnected”. In GNOME System Settings in Display menu it also available. And it changes correct when I disconnect HDMI display, and reconnect again. It works when I add line

Option "PrimaryGPU" "Yes"

in “10-amdgpu-nvidia-drm-outputclass.conf” at “nvidia” line, but after rebooting login screen appears at HDMI, and all apps running using NVidia card, there is no more AMD. Any ideas, how to activate NVidia card at HDMI port, but use default graphics as AMD?

11

has anyone reported it upstream? and where exactly would be “upstream” - nvidia or amdgpu?

12

Sorry for the necrobump but I really need the answer to this.

Any ideas, how to activate NVidia card at HDMI port, but use default graphics as AMD?

Have you found the answer to this? Please reply there if you do.

I am facing the same issue and have also opened a ticket here
