Monitors attached to the 2º GPU are ignored

[Zeioth]

Short description

Out of my 6 monitors, only the 3 attached to the first GPU turn on.

Details

Everything was working fine until I upgraded from hyprland stable to hyprland-git (with aquamarine) today. I've read the docs A and B so I made the required change from

WLR_DRM_DEVICES=/dev/dri/card1:/dev/dri/card0

to

AQ_DRM_DEVICES=/dev/dri/card1:/dev/dri/card0

hyprctl monitors can list all my monitors correctly, it is just they don't turn on anymore.

Logs

Using Hyprland > mylog from TTY with HYPRLAND_TRACE=1. https://pastebin.com/raw/fubmZ0Ji

(Nothing super remarkable here)

also I haven't changed the config file, it is the same one as usual: https://github.com/Zeioth/zeioth-hyprland-config

probably related to #40

[romanstingler]

can you try building all packages new. Something like this. Meanwhile, I guess most outputs except Thunderbolt should be fixed/

yay -S aquamarine-git hyprlang-git hyprcursor-git hyprutils-git hyprland-git --overwrite="*"

[Zeioth]

@romanstingler yes i can test give me a sec

[Zeioth]

Issue remains

[romanstingler]

please build yay -S hyprland-git aquamarine-git new and add env = AQ_NO_MODIFIERS,1 to your hyperland.conf

[Zeioth]

Issue remains.

I've debugged this a bit more and all monitors turn on fine when the GPUs are passed in the default order.

AQ_DRM_DEVICES=/dev/dri/card0:/dev/dri/card1

Doing the opposite is what causes some monitors to not turn on at all.

AQ_DRM_DEVICES=/dev/dri/card1:/dev/dri/card0

[Zeioth]

The point is to be able to decide what GPU commands what monitors. This is important because the monitors attached to the secondary GPU will max 30 FPS (this also happened in wlroots).

is card1 nvidia? Reverse-feeding from nvidia to an igpu of any brand is physically impossible due to hardware limitations

[Zeioth]

@vaxerski both AMD.
